What this switch is and where it goes
The D41L-2ZDGE-N2 is a high-coded guard locking door switch from Omron's D41L series, built for harsh environments or hygienic requirements. It uses an RFID actuator — meaning the switch only recognizes its paired coded actuator, not a standard metal cam or magnet. That coded pairing prevents defeat by a common screwdriver or loose metal, which is the main reason you spec this over a basic interlock. The solenoid is power-to-lock: the lock engages when power is applied and releases when power is removed. The holding force is 1,150 N. Conduit entry is M12, a common metric size for sensor and safety-switch cabling. The OSSD outputs are configured for guard monitoring only — no integrated latch feedback or auxiliary signals on the safety channel. If your safety circuit needs dual-channel OSSD feedback from the door position, this covers that; if you also need a separate solenoid-status signal, you'd add that externally.
Coding and re-teaching
Individual coding re-teaching is enabled. That means if you replace the actuator (say the door-mounted RFID tag gets damaged), you can teach the new actuator to the switch head without replacing the whole switch body. Saves a line-down swap to a complete new unit — just re-teach and go. This is a field-service feature, not something every guard switch offers.
