Schmersal AZ 16-03ZVRK-1762 Safety Switch

Schmersal AZ 16-03ZVRK-1762 Safety Switch is a front-mount, key-operated safety switch from the AZ 16 family that uses a separate actuator for guard-interlock installations. Housed in black, IP67-rated plastic, the unit is designed to be mounted on a machine guard or door while the actuator is installed separately, allowing reliable protection of personnel when the guarding device is opened. The model provides three normally closed safety contacts (NC x3) for monitoring the guard status in safety circuits, and the 03 designation in the part number identifies this NC configuration. The 1762 suffix denotes the front-mounting variant, a configuration commonly used where external actuation is preferred or required by the machine layout. As part of Schmersal's safety interlock ecosystem, AZ 16-03ZVRK-1762 can be integrated with compatible actuators and control devices to form a cohesive guarding circuit that aligns with typical machine-safety applications. Typical applications include guarding doors and gates on industrial machinery, where reliable interlock of access points is essential to ensure the machine remains safely de-energized when a guard is opened. This compact, separate-actuator design combines IP67 protection, a rugged plastic housing, and a front-mounting configuration to offer installation flexibility without compromising safety.
