It uses a key-actuated head that can be oriented in four directions, giving flexibility when mounting to a guard door. The switch contacts break before the solenoid releases, so the machine control sees the door-open signal before the lock actually opens — a sequence that matters for safety circuit integrity. Contact configuration is 1 normally-open plus 3 normally-closed. The NC contacts are the safety channel; the NO can serve as a lock-status feedback to the PLC. Switching capacity is 3 A at 240 V AC, or 270 mA at 250 V DC — enough for direct control of a safety relay or small contactor coil, but if you're driving a larger load, buffer it through an interface relay. Rated electrical life is 500,000 cycles, mechanical life 1 million cycles. That's solid for a production line running a few cycles per minute — expect years of service before contact wear becomes an issue, assuming the load stays within the rated switching current. ## Environment and mounting IP67 rating means the switch body and the head seal against dust and temporary water immersion — suitable for washdown areas in food processing or wet machining. The screw terminals accept 0.2–2.5 mm² wire; strip length around 8 mm keeps the conductor fully under the clamp without exposed strands. Dimensions are 88.5 mm wide, 95 mm tall, 35.5 mm deep — a compact footprint that fits standard guard-door profiles. If you're sourcing for a new design, verify the actuator key type matches your door profile — the switch accepts a key actuator, not a separate solenoid driver.","metaTitle":"Omron D4NL2CFGB Safety-Door Switch, Solenoid Lock, 1NO/3NC,","metaDescription":"Omron D4NL2CFGB safety-door switch with solenoid lock, 1NO/3NC contacts, IP67, screw terminals.
