What a magnetic-latching DPDT plug-in relay actually does
The Omron MY2K-US-DC48 is a magnetic-latching relay in the MYK family, defined as a DPDT (2-pole) plug-in device whose contacts hold their last position after the coil is de-energized — ideal for memory- and data-transmission circuits where the output state must survive a power interruption. The set and reset coils run at 48 VDC with a set power of approximately 1.3 W and a reset power of approximately 0.6 W. Two separate coil inputs on the same relay let a logic pulse flip the contacts in either direction without continuous coil hold current, which is the defining advantage of the latching form factor over a standard non-latching DPDT relay.
Contact ratings and what they mean for the load
Maximum switching current is 3 A with a maximum switching voltage of 250 VAC or 125 VDC. The headline 3 A figure is the resistive ceiling; on inductive loads the ratings drop to 0.8 A at 220 VAC and 1.5 A at 24 VDC, while on resistive loads they hold at 3 A at both 220 VAC and 24 VDC. Switching power tracks the same split: 176 VA / 36 W on inductive loads versus 660 VA / 72 W on resistive loads. For a buyer matching this relay to a real load, the duty category — not the headline 3 A — is the figure that governs fit: a relay driving a solenoid or small contactor coil must be sized against the 0.8 A inductive rating, not the 3 A resistive figure.
Low-level switching and panel-side integration
The minimum load of 1 mA at 1 VDC means the contacts are rated for dry-circuit and low-level signal switching, so the relay can sit at the boundary between logic-level telemetry and a higher-current output without a separate interposing relay. Operating temperature runs from -55 °C to 60 °C, covering both unheated outdoor cabinets and standard panel interiors. The plug-in terminal style fits the standard MY-series octal/ blade socket pattern used across the Omron MY family, so panel wiring is a matter of matching the correct socket and pinning the two coil inputs plus the DPDT commons to the wiring layout. RoHS compliance is confirmed on the device record.
