The D4B4115N: Rated at 2 A at 400 V AC and 400 mA at 250 V DC, this switch handles pilot-duty control circuits — think PLC inputs, relay coils, contactor auxiliaries — not direct motor loads. The DC rating is the one to watch: 400 mA at 250 V DC is typical for a snap-action microswitch; if your load is inductive (a DC relay or solenoid), add a flyback diode across the load to protect the contacts from arcing. The 1NO/1NC contact block gives you one normally-open and one normally-closed set in a single housing — useful for interlocking a guard door with a status feedback signal back to the safety circuit.
Termination and integration details
The IP67 seal holds up to hose-down cleaning, so it can be mounted directly on a conveyor frame or machine guard without a secondary enclosure. The roller lever actuator is field-rotatable in 90° increments, letting you align the lever to the cam approach direction on site.
