Omron PYFZ-14-E 14-pin DIN rail screw terminal relay socket for MY4 and H3YN plug-in relays in industrial control panels

Omron PYFZ-14-E Socket, DIN Rail/Surface Mounting, 14-Pin, Screw Terminals (Standard) — Specs, Compatibility & Selection Guide

If you are specifying a socket for an Omron MY4, MY4-GS, H3YN, or MY2K relay and need to confirm the right 14-pin base before your panel ships, the Omron PYFZ-14-E is the part most control engineers reach for first. It is a 14-pin, 4PDT relay socket supporting both DIN rail and surface/screw mounting with screw terminals — a combination that covers the majority of industrial control panel layouts without compromise. The PYFZ-14-E measures approximately 29.5 mm wide, 72 mm tall, and 31 mm deep, making panel space planning straightforward from the first layout pass.

Who Should Specify the Omron PYFZ-14-E — and Who Should Look at an Alternative

This socket is the right call for panel builders, OEM machine designers, and plant maintenance teams who are working with 14-pin Omron plug-in relays and want a dependable, widely stocked screw-terminal base. Specify the PYFZ-14-E when all of the following apply:

  • Your relay is a 14-pin Omron type — specifically MY4, MY4-GS, H3YN, or MY2K — and you need the matching 4PDT socket footprint.
  • Your panel uses DIN rail mounting, surface/screw mounting, or both, and you need a socket that handles either without adapter hardware.
  • Screw terminals are your wiring standard and conductor size range is within the PYFZ-14-E specification.
  • Your project requires electrical ratings and approvals consistent with the MY4-family relay class and your jurisdiction's compliance requirements.
  • Panel layout allows for the 29.5 mm × 72 mm × 31 mm footprint with adequate clearance for terminal access and relay removal.

If your application calls for push-in tool-less wiring, touch-safe terminals, a different pin count (8-pin or 11-pin), or a non-Omron relay footprint, a different socket variant is likely the better fit — the comparison table below covers the key alternatives.

What the Omron PYFZ-14-E Actually Does in a Control Panel

The PYFZ-14-E is the mechanical and electrical interface between the fixed field wiring in your panel and the plug-in relay that does the switching. Once the socket is wired in place — coil circuit, common terminals, and contact circuits terminated to screw terminals — the relay itself becomes a tool-free field-replaceable component. Maintenance technicians can pull a failed MY4 relay and snap in a replacement without touching a single wire. That is the core value proposition of the plug-in relay and socket system, and the PYFZ-14-E delivers it reliably across both DIN rail and surface-mounted panel configurations.

The socket is finished in black and is documented by Omron as compatible with MY4, MY4-GS, MY2K, and H3YN timing relay families. With a 14-pin, 4PDT footprint, it accepts the full four-pole double-throw contact arrangement that makes the MY4-family relays useful for complex interlocking and sequencing work. Screw terminals keep the socket solidly in the mainstream of industrial wiring practice — straightforward to terminate, easy to inspect, and retorqueable during periodic maintenance.

Where the PYFZ-14-E Sits in a Typical Control System

The PYFZ-14-E occupies the interface layer between a PLC or hardwired control circuit and the relay contacts that switch field loads. It is not an active component — it is the reliable, passive connector that makes the active relay a swap-in part.

  • PLC digital output or hardwired control circuit supplies the coil voltage signal to the PYFZ-14-E coil terminals.
  • The PYFZ-14-E socket is wired in place on the DIN rail or mounting plate with field conductors terminated to screw terminals.
  • An Omron MY4, MY4-GS, H3YN, or MY2K relay is inserted into the socket, completing the coil and contact circuit.
  • The relay contacts switch downstream loads — small motors, contactor coils, signal circuits, or timing functions depending on relay type.
  • Hold-down clips and release levers secure the relay in the socket and allow controlled removal without tools during maintenance or replacement.

Typical Applications and Industries for the Omron PYFZ-14-E

The PYFZ-14-E is most at home in industrial control panels where MY4-family relays handle general-purpose switching, interlocking, and sequencing. In machine control, it is the standard base for MY4 or MY4-GS relays switching contactor coils, solenoid valves, or signal circuits. Paired with H3YN timing relays, the same socket supports start/stop delays, interval timers, and sequence logic — a common requirement in conveyor, packaging, and material handling systems.

OEM machine builders who standardize on Omron relay hardware specify the PYFZ-14-E across multiple machines so that field service teams carry a single socket type for all sites. This simplifies both inventory management and training. In MRO applications, the socket is frequently ordered as a replacement when worn or damaged bases are found during panel audits — the screw-terminal format means the existing field wiring stays in place while only the socket is changed out.

Building automation and HVAC control panels, water and wastewater treatment systems, and food and beverage process lines all represent secondary application areas where the PYFZ-14-E appears as part of a standardized Omron relay panel build.

If your relay is a 14-pin Omron type but your wiring standard calls for push-in terminals, the push-in variant is worth evaluating before finalizing your BOM — check current availability and compare options at LeadTime.ca.

Expert Verdict: Is the PYFZ-14-E the Right Socket for Your Project?

The Omron PYFZ-14-E earns its place as the default relay socket specification wherever MY4, MY4-GS, H3YN, or MY2K relays are in the design. It is explicitly documented as compatible with those 14-pin families, supports both DIN rail and surface mounting so it fits practically any control panel layout, and the screw-terminal format is something every panel wirer understands and can work with confidently. The physical dimensions — approximately 29.5 mm wide, 72 mm tall, 31 mm deep — make panel planning predictable. For panel builders, OEMs, and plant maintenance teams who have already standardized on Omron MY4-family hardware, this socket is the straightforward, low-risk choice that simply does what is expected of it without requiring any special justification in a design review.

Where the PYFZ-14-E is not the right answer is equally clear. If your panel wiring standard has moved to push-in, tool-less terminals — increasingly common in high-density or rapid-build OEM environments — then a push-in socket variant is the better fit even if the pin count and relay family are identical. If the relay you are sourcing is not a 14-pin Omron type, this socket should not be in the BOM at all; the 8-pin and 11-pin Omron socket families handle MY2 and MY3 relays respectively. And if your application requires touch-safe terminal guards or special mixed-voltage terminal separation for safety compliance, investigate whether a specialized socket variant is needed before specifying PYFZ-14-E as a standard substitute.

From a procurement standpoint, the PYFZ-14-E is a standard catalogue item with the kind of availability profile that makes it a safe part to carry as a stocking spare. That said, large project quantities and regional stock variation mean it is worth confirming lead time before committing a build to a tight delivery window. Working with a specialist distributor rather than a generic channel gives you access to compatibility validation before an order goes in — the kind of relay-to-socket cross-check that catches wrong-pin-count errors at the quote stage rather than at panel assembly.

What Engineers Need to Know Before Ordering the Omron PYFZ-14-E

Model-specific community discussion on the PYFZ-14-E is sparse across forums including r/PLC, PLCTalk, PLCS.net, and MrPLC — and that is actually a useful data point. A relay socket that generates no recurring complaint threads in the automation community is typically one that does its job quietly and reliably. The PYFZ-14-E belongs to the mature, commodity tier of industrial relay hardware: it is not a part that sparks debate, because specifying it correctly and wiring it carefully leaves nothing to debate about.

The issues that do surface in family-level relay socket discussions are almost entirely about selection errors and wiring practice rather than product failures. The most frequently mentioned ordering mistake is selecting a socket with the wrong pin count — choosing an 8-pin or 11-pin base for a MY4 relay, or vice versa. This is an easy error to make when working from a partial part number or when copying a BOM from a different machine variant. The second pattern is ordering a different socket variant — a push-in terminal type, for example — when the existing panel wiring or plant standard expects screw terminals. Both errors are resolved at the selection stage, not after delivery.

The third recurring theme in community discussions is pin numbering awareness. Engineers moving between manufacturers' relay sockets note that pin numbering conventions differ, and that assuming the PYFZ-14-E follows the same layout as a different brand's 14-pin socket can lead to miswiring. The answer is straightforward: always wire from the Omron pinout diagram for this specific socket, not from memory or a diagram for a different product. When community feedback is limited for a specific part, the specialist distributor becomes the most efficient place to validate compatibility, confirm current stocking levels, and catch selection errors before an incorrect part ships to your site. That is exactly the role LeadTime.ca plays when engineers call before finalizing a relay socket order.

Wiring and Installation Overview for the Omron PYFZ-14-E

  • For DIN rail mounting, snap the socket onto a standard DIN rail and confirm it is fully engaged before terminating field wiring; for surface mounting, fix the socket to the panel plate using appropriate screws through the designated mounting points.
  • Use the Omron pinout diagram specific to the PYFZ-14-E to identify coil terminals, common terminals, and normally open/normally closed contact terminals before making any connections — do not rely on diagrams from other manufacturers' sockets.
  • Terminate conductors to screw terminals within the specified conductor size range; tighten to the recommended torque value per Omron documentation to prevent intermittent faults or hot spots from under-tightened connections.
  • Insert the compatible relay — MY4, MY4-GS, H3YN, or MY2K — by aligning the 14-pin pattern carefully and seating the relay fully; apply the hold-down clip where vibration or frequent access is a concern.
  • Before energizing, perform continuity checks between related terminals and verify there is no unintended short between coil and contact circuits; consult the full Omron installation datasheet for complete wiring procedures and torque specifications.

Compatible Relay Families and System Accessories

The PYFZ-14-E is documented by Omron as compatible with the following 14-pin plug-in relay families. Confirm the specific relay catalog number against the current Omron compatibility table before finalizing your specification.

  • MY4 — General-purpose 4PDT plug-in relay, the primary relay type this socket is designed for.
  • MY4-GS — MY4-family relay with gold-plated contacts for low-level signal switching applications.
  • MY2K — 4PDT plug-in relay variant within the MY-family group compatible with the 14-pin socket format.
  • H3YN — Solid-state timer relay in 14-pin format; the PYFZ-14-E accepts H3YN timing relays for sequence control and delay logic applications.
  • Hold-down clip and release lever — Accessories that secure the relay in the socket and allow controlled removal; confirm whether these are included with the PYFZ-14-E or must be ordered separately from current Omron documentation.

Wrong-Part Prevention Checklist Before You Order the PYFZ-14-E

Use this checklist verbatim before finalizing any PYFZ-14-E order. Every point represents a real ordering error that panel builders and procurement teams have encountered.

  1. Confirm the relay is a 14-pin Omron MY4/MY4-GS/H3YN/MY2K style; do not use this socket for 8-pin or 11-pin relays.
  2. Verify the required mounting method (DIN rail vs panel/surface) matches what PYFZ-14-E offers.
  3. Check your terminal preference (screw terminals) and that the conductor size range fits your wiring standard.
  4. Confirm the socket's electrical rating and approvals meet or exceed the relay and load requirements in your jurisdiction.
  5. Ensure the panel layout has enough space for the socket dimensions (width/height/depth) and access to terminal screws.
  6. Check if you need additional hold-down clips or accessories and whether they are included or must be ordered separately.

If any item on this checklist raises a question before you order, contact the LeadTime.ca team — our application engineers can cross-check relay-to-socket compatibility and confirm current stock before your order is placed.

Frequently Asked Questions

Which Omron relays are confirmed compatible with the PYFZ-14-E socket?

Omron documents the PYFZ-14-E as compatible with MY4, MY4-GS, MY2K, and H3YN relay families — all of which use the 14-pin, 4PDT footprint. Do not use this socket with 8-pin MY2 or 11-pin MY3 relays; those require their own dedicated socket families. Always cross-check the specific relay catalog number against Omron's current compatibility table before finalizing the BOM.

Can the PYFZ-14-E be mounted on both DIN rail and a flat panel surface?

Yes. Omron specifies the PYFZ-14-E for both DIN rail mounting and surface/screw mounting, which is one of its practical advantages over sockets that support only one method. Confirm your panel layout and choose the appropriate mounting approach based on available space and your panel building standard. Ensure adequate clearance for terminal access and relay removal in either configuration.

Can I use a non-Omron relay in the PYFZ-14-E socket?

Mechanically, some third-party 14-pin relays may appear to fit, but Omron specifies this socket for its own MY4-family and H3YN relays and does not certify compatibility with other manufacturers' products. Pin layout, contact pressure, and electrical ratings may differ even when the physical footprint appears similar. For critical applications, use matched Omron relay and socket pairs; if a third-party relay must be used, verify mechanical and electrical compatibility against both manufacturers' data before applying power.

What is the difference between the PYFZ-14-E and the PYF-14-E?

Both are 14-pin Omron relay sockets for the MY4 family with screw terminals. The PYFZ-14-E and PYF-14-E are closely related variants within the same socket family; differences may include minor form factor details or accessory provisions. Before substituting one for the other, compare the mechanical dimensions and any application-specific differences in the current Omron product documentation to ensure the substitution does not affect panel fit or relay seating.

How do I identify a wiring fault in the PYFZ-14-E without replacing it unnecessarily?

Start by removing the relay and performing a visual inspection of the socket terminals for discoloration, deformation, or signs of overheating. Use a multimeter to check continuity between each terminal and the corresponding relay pin socket, and verify that all screw terminals are properly tightened to the specified torque. Insert a known-good relay from a working circuit into the suspect socket to determine whether the fault follows the relay or stays with the socket — this step isolates the faulty component before any part is replaced.

Is the PYFZ-14-E a standard stocked item or does it require lead time?

The PYFZ-14-E is a standard catalogue item in the Omron relay socket lineup and is generally carried in stock by major industrial automation distributors. Lead times are typically short for standard order quantities, though large project buys or regional stock variation can extend availability. Confirm current stock and lead time with your distributor before committing a project timeline — pricing and availability are shown live on the PYFZ-14-E product page at LeadTime.ca.
