Description
The Omron D4NS-1AF is a compact, high-reliability safety-door switch designed for machine guarding applications. This switch features a positive-break mechanism (NC contact) that meets safety standards, ensuring immediate power cutoff when a door or guard is opened. With a compact design for easy installation in tight spaces and a durable metal actuator, it provides long service life even in high-cycle applications. The switch is rated for high-current loads, allowing direct control of safety circuits without additional relays in many cases.
