Omron P2RFZ-08-E Relay Socket — G2R-2-S Compatibility Guide
Omron P2RFZ-08-E Socket, DIN Rail/Surface Mounting, 8-Pin, Screw Terminals — Specs, Compatibility and Buying Guide
Controls engineers and panel builders searching for the correct socket to pair with an Omron G2R-2-S relay land on the P2RFZ-08-E because it ticks the three hard constraints that matter at the panel assembly stage: 8-pin DPDT compatibility, DIN rail or surface mounting flexibility, and screw terminals in a slim 15.5 mm wide footprint. Getting the socket right before the relay ships prevents the most common and costly commissioning delay in relay-based I/O panels — arriving at FAT with the wrong pin count. The Omron P2RFZ-08-E is the socket Omron documents as compatible with G2R-2-S and K7L series units, and this review covers every dimension of that decision.

Who Should Buy the Omron P2RFZ-08-E — and Who Should Not
This socket is the right choice when all of the following apply to your project:
- Your relay is an Omron G2R-2-S or a K7L series unit explicitly listed as compatible with the P2RFZ-08-E
- You need an 8-pin socket for a DPDT relay — not a 5-pin SPDT configuration
- Your panel layout accommodates DIN rail or screw surface mounting with a 15.5 mm wide socket
- Screw terminals suit your panel wiring standard — forked or round ferrules are supported
- The electrical ratings and applicable approvals on the P2RFZ-08-E meet your system voltage, current, and code requirements
- Physical clearance of approximately 79 mm height and 61 mm depth fits your enclosure layout
If your relay is a 5-pin SPDT type, the P2RFZ-05-E is the correct model. If your plant standard requires push-in terminals or a different socket family such as PYF or PYFZ, those variants should be evaluated instead. If you are unsure which model applies, contact the LeadTime.ca team before ordering.

What the Omron P2RFZ-08-E Actually Does in a Control Panel
The Omron P2RFZ-08-E belongs to the P2RFZ Common Sockets family and serves one specific purpose in the relay chain: it provides the permanent, field-wired base that the plug-in relay snaps into. All control wiring — coil supply, load contacts, common returns — terminates at the socket's screw terminals. The relay itself remains unplugged until commissioning, which means every wire in the enclosure can be dressed, labeled, and verified before a single relay is inserted. When a relay fails in service, it can be swapped in seconds without touching a single terminal screw.
The P2RFZ-08-E accepts Omron G2R-2-S plug-in relays and K7L series level controller units. The 8-pin configuration matches the DPDT contact architecture of the G2R-2-S, and the screw terminal design supports forked and round ferrule terminations used in standard control wiring practice. At 15.5 mm wide, the socket allows dense DIN rail rows without the spacing penalty that wider relay bases impose. The black housing provides visual distinction in multi-component panels and matches the standard Omron P2RFZ family aesthetic.
Where the P2RFZ-08-E Sits in a Typical Control System
The P2RFZ-08-E occupies the interface layer between the panel's field wiring and the plug-in relay, sitting downstream of the control output and upstream of the load circuit. In a typical DIN rail cabinet, the signal chain looks like this:
- PLC digital output module or control circuit provides coil switching signal to the socket's coil terminals
- P2RFZ-08-E socket is DIN rail or surface mounted and carries all terminal wiring for the relay position
- G2R-2-S relay plugs into the socket, bridging the coil control side to the contact switching side
- Load circuit — motor starter, solenoid valve, indicator, or auxiliary contact — connects to the socket's contact terminals
- External fuse or circuit breaker sized to the load provides overcurrent protection for the contact circuit
Industries and Applications Where This Socket Is Specified
The P2RFZ-08-E appears on bills of materials across a wide range of industries wherever G2R-2-S relays are used as general-purpose output switching elements. Machine builders specify it in compact PLC cabinets where a slim 15.5 mm socket width helps fit dense relay rows into limited enclosure widths. Water and wastewater panel shops use it with K7L level controllers to provide pluggable, field-replaceable relay bases in pump and tank level control panels. OEM equipment manufacturers standardize on it across a machine platform so that maintenance teams carry a single socket spare type.
In food and beverage and packaging lines, panel designers value the straightforward screw terminal interface and secure relay retention for environments where vibration and frequent relay replacement cycles occur. HVAC control panel builders include it wherever a slim, DIN rail-mounted relay socket is needed for fan, pump, or damper output switching.

| Model | Pins | Terminal Type | Mounting | Key Difference vs P2RFZ-08-E | Notes |
|---|---|---|---|---|---|
| P2RFZ-08-E | 8 | Screw | DIN rail / surface | Baseline model in this review | For G2R-2-S, K7L |
| P2RFZ-08 | 8 | Screw | Similar | Non-E version; verify approvals and dimensions | Use if matching legacy installs |
| P2RFZ-05-E | 5 | Screw | DIN rail / surface | 5-pin; for SPDT relay types | Do not use for 8-pin relays |
| PYF / PYFZ series (Omron) | Varies | Screw or push-in | DIN rail / surface | Different form factor and relay compatibility | System-level alternative; verify relay fit |
| Competitor 8-pin sockets | 8 | Varies | DIN rail / surface | Check pinout and approvals before use | Not a direct drop-in; verify compatibility |
If your relay is a 5-pin SPDT rather than an 8-pin DPDT, the P2RFZ-05-E is the correct selection — ordering the P2RFZ-08-E for that relay will result in a mismatch discovered at panel assembly. Check current availability for the P2RFZ-08-E at LeadTime.ca and confirm your pin count before adding to cart.
Expert Verdict: Is the P2RFZ-08-E the Right Long-Term Standard?
The Omron P2RFZ-08-E earns its place on the BOM whenever G2R-2-S relays are specified. It delivers what the buyer profile that matters most — OEM panel shops, machine builders, and Omron-standardized plants — actually needs: a slim 15.5 mm wide socket that packs efficiently into DIN rail rows, screw terminals that electricians can wire confidently, and documented compatibility with both G2R-2-S and K7L units. The approximately 38 g, 79 mm tall socket brings no surprises to a panel that is already dimensioned around this form factor, and the dual mounting option means it adapts to both new DIN rail builds and legacy surface-mount panels without a redesign. For teams that have standardized on Omron G2R relays, specifying the P2RFZ-08-E across all 8-pin positions simplifies spares management and means any electrician on site already knows the product.
The honest limits are worth naming. Engineers who need push-in terminals as a plant standard will find screw-only terminals a friction point — the PYFZ series is worth evaluating in that case. Applications where load currents push toward or beyond 5 A need to verify the full datasheet rating rather than relying on the nominal figure; external protection sized to the circuit is always required regardless. If your relay is from a different manufacturer with an 8-pin pinout that appears similar, do not assume compatibility — pinout and approval differences between relay families make this a meaningful risk. And projects requiring sockets with higher current capacity, specialized industrial approvals beyond what the P2RFZ-08-E carries, or large wire termination capacity should step to a higher-capacity socket family rather than forcing the P2RFZ-08-E into an application it was not dimensioned for.
From a procurement standpoint, the P2RFZ-08-E is commonly stocked by authorized distributors with good availability for standard project quantities. For larger OEM orders or project-specific quantities, lead times measured in several weeks apply for factory replenishment, so plan procurement alongside your BOM finalization rather than at the last stage of the build. Buying through a specialist automation distributor means compatibility can be validated against the current Omron documentation before the order ships, catching pin-count or approval mismatches before they become panel rework.

What Engineers Need to Know Before Ordering the P2RFZ-08-E
Model-specific discussion threads for the P2RFZ-08-E are sparse across forums including Reddit r/PLC, PLCTalk, PLCS.net, and MrPLC — most community feedback surfaces at the broader P2RFZ and Omron relay socket family level. Where community data is thin, the wrong-part prevention checklist and documented ordering mistakes become the most reliable pre-purchase resource. The issues that do appear repeatedly in community discussions are almost entirely administrative rather than technical: wrong pin count, overlooked suffix differences, and mounting oversights. The socket itself draws positive feedback for relay retention and screw terminal reliability.
Panel builders across multiple forums note that Omron sockets in the P2RFZ family hold G2R relays firmly and tolerate frequent relay changes without noticeable wear to the socket housing. The 15.5 mm slim width draws consistent praise from engineers fitting many relay positions into compact enclosures — it is explicitly mentioned as a reason to standardize on this form factor over wider alternatives. Screw terminals are reported as reliable when properly torqued, with very few reports of spontaneous loosening in normal service conditions. The complaints that do appear — tight terminal spacing for heavier-gauge wires, confusion between 5-pin and 8-pin variants, and occasional socket shift when DIN rail end clamps are omitted — point clearly to wiring practice and ordering discipline rather than product defects.
The single most-reported ordering mistake is selecting the P2RFZ-05-E for an 8-pin G2R relay, with the mismatch discovered at panel assembly rather than at the ordering stage. A secondary recurring mistake is treating the non-E variant (P2RFZ-08) as identical to the P2RFZ-08-E — the suffix difference can reflect approval or design revision differences that matter in regulated or export applications. Mixing P2RFZ sockets with PYF or PYFZ family sockets under the assumption that all Omron 8-pin sockets are interchangeable is also flagged repeatedly. The checklist below addresses all of these traps directly.
Wiring and Installation Overview
- Mount by hooking the top of the socket clip onto the DIN rail and pressing the bottom until it clicks; confirm the latch is fully engaged before wiring and install end clamps to prevent lateral movement under vibration
- For surface mounting, use the screw mounting holes and verify panel hole spacing matches the socket footprint before drilling
- Consult the relay and socket terminal diagrams to identify coil and contact pin assignments before connecting any wires — do not rely on visual similarity to other relay families
- Strip control wires to the recommended length, fit forked or round ferrules where applicable, insert into the correct screw terminals, and tighten firmly; tug each wire after termination to confirm retention
- After all wiring is complete, insert the G2R-2-S relay with correct orientation until fully seated, install any hold-down clip, and use the release lever for relay removal to protect the socket housing and pins
Wrong-Part Prevention Checklist
Before placing an order for the Omron P2RFZ-08-E, verify every item on this checklist against your relay spec and panel requirements:
- Confirm the relay model (e.g., G2R-2-S) is explicitly listed as compatible with P2RFZ-08-E.
- Verify 8-pin relay vs 5-pin relay; do not mix P2RFZ-08-E with 5-pin relays.
- Check mounting preference: DIN rail vs pure panel mount; ensure this socket style fits the enclosure.
- Confirm screw-terminal requirement; if plant standard is push-in, select the matching variant instead.
- Ensure the socket's electrical rating and approvals meet the system voltage, current, and applicable codes.
- Check physical size and clearance (height approx. 79 mm, width 15.5 mm, depth 61 mm) against panel layout.
- Verify quantity and lead time with distributor for project deadlines, especially for larger orders.
- Make sure any necessary hold-down clips or jumpers for the application are included or ordered separately if not standard.
If any item on this checklist cannot be confirmed from the datasheet alone, contact the LeadTime.ca team to validate compatibility before the order is placed.
Frequently Asked Questions
Is the P2RFZ-08-E compatible with all Omron G2R relay variants, or only the G2R-2-S?
Omron's documentation lists G2R-2-S and K7L series units as the compatible relay families for the P2RFZ-08-E. Compatibility with other G2R variants should be verified against Omron's current compatibility chart for the P2RFZ socket family before assuming interchangeability, since pin assignments and coil termination positions can vary across G2R sub-models.
What is the practical current rating of the P2RFZ-08-E and does it cover the load in my application?
The P2RFZ-08-E carries a 5 A rating per information from authorized distributors and Omron family data. Verify this figure against the current Omron datasheet for the most up-to-date rating, and always include external overcurrent protection — a fuse or circuit breaker sized to the load — in the contact circuit regardless of socket rating.
What is the actual difference between P2RFZ-08 and P2RFZ-08-E, and does it affect which one I should order?
The -E suffix in Omron part numbering typically denotes a regional approval variant or a design revision relative to the non-suffixed version. For applications where specific approvals such as UL, CSA, or CE are required, confirming that the P2RFZ-08-E carries the applicable certification is important before substituting the P2RFZ-08 or vice versa. Check Omron's current documentation for the specific approval differences and verify against your project's compliance requirements.
Can I use the P2RFZ-08-E with relays from other manufacturers if the pin count is 8?
An 8-pin relay from another manufacturer may appear physically similar but differ in pin assignment, contact layout, and coil terminal positions. Using the P2RFZ-08-E with a non-Omron relay without verifying pinout against both the relay and socket diagrams carries a meaningful risk of miswiring. Omron's documentation covers G2R-2-S and K7L compatibility; cross-brand use requires independent verification and is not covered by Omron compatibility charts.
Can the P2RFZ-08-E be panel-mounted without a DIN rail?
Yes — the P2RFZ-08-E supports both DIN rail mounting and surface (screw) mounting directly to a panel backplate. For surface mounting, the panel hole spacing must match the socket's mounting footprint. Verify the physical dimensions — approximately 79 mm height, 15.5 mm width, 61 mm depth — against your panel layout before drilling.
What wire gauge range works with the screw terminals on the P2RFZ-08-E?
The screw terminals support forked and round ferrule terminations consistent with standard control wiring practice. Community feedback notes that terminal spacing can feel tight for heavier-gauge wires, so verify the wire gauge range in the current Omron datasheet for the P2RFZ-08-E before specifying wires at the upper end of the range. Using ferrules improves termination quality and reduces the risk of strand damage at screw terminals.
