The Omron D4SLN2NFGDN is a guard lock safety-door switch from the D4SL series, with a 2NO / 4NC contact configuration. It uses a key-type actuator and terminates via a connector, rated IP67 for washdown environments. Switching capacity is 1.5 A at 120 VAC or 220 mA at 125 VDC, with an electrical service life of 150,000 cycles and a mechanical life of 1 million cycles.
Dimensions are 39 mm wide by 39 mm deep by 155 mm tall. The head can be oriented in four directions, which simplifies alignment with the guard door. The connector termination reduces wiring time compared to a hardwired gland entry, but verify the mating connector part number separately — the switch ships without one.
