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.","metaTitle":"D4B4115N Limit Switch, Roller Lever, 1NO/1NC, IP67, 2 A AC","metaDescription":"D4B4115N limit switch from the D4B series.
