The Omron D4SLN4RDADN is a guard-lock safety-door switch from the D4SL series, with six normally-closed contacts (6NC) and a key-actuated head that can be oriented in four directions. It switches AC loads up to 1.5 A at 120 V and DC loads up to 220 mA at 125 V, with an electrical service life of 150,000 cycles and a mechanical life of 1 million cycles. The IP67-rated body and connector termination make it suitable for washdown environments in food-and-bev or pharmaceutical lines where a positive-break safety interlock is required.
