The Omron D4NL4CFAB is a guard-locking safety-door switch from the D4NL Series, built for interlocking access panels on machinery where a locked guard must be verified before the machine can operate. Its 3NC/1NO contact configuration gives three normally-closed safety channels for the monitoring circuit and one normally-open auxiliary for status feedback — standard for Category 3 or 4 safety circuits per ISO 13849-1 when wired correctly. Rated to switch 10 A at 250 VAC, the contacts handle motor control or solenoid loads directly in many small-to-medium machines. The IP67 rating means the switch body and locking mechanism withstand washdown environments — suitable for food processing, beverage lines, or any area where hose-down cleaning is routine.
The D4NL4CFAB measures 88.5 mm wide, 95 mm tall, and 35.5 mm deep — a compact footprint that fits standard safety-door cutouts in the D4NL family.
