Manufacturer: OMRON
Condition: New and Unused, Surplus.
Overview of Omron G4Q-212S
The Omron G4Q-212S is a ratchet relay featuring a double-pole double-throw (DPDT) contact configuration with a unique ratchet mechanism that ensures positive alternate transfer or switching operation at each pulse input. This relay is suitable for applications that require alternate operation or switching, such as motor control. It supports coil voltages including 12 VAC and 24 VAC versions, among others, and is available in both open and cased models.
