Guardmaster 440N Non Contact Switch (440N-Z21US2H)

The SensaGuard Rectangular Plastic Sensor with a unique coded actuator is a non-contact safety switch designed for reliable guard monitoring in industrial environments. Featuring RFID technology, it provides high tamper resistance and ensures that only uniquely coded actuators can activate the sensor, enhancing machine safety.

This model offers an assured sensing distance of 25 mm (0.98 in) and includes LED indicators for door status and diagnostics, simplifying setup and maintenance. It provides two PNP safety outputs (0.2 A each, +24V DC max) and one PNP auxiliary output for status monitoring.

Housed in a rectangular plastic enclosure, the SensaGuard sensor is connected via a 6-inch pigtail with an 8-pin Micro (M12) connector, allowing quick integration into existing control systems. Its compact and durable design makes it ideal for applications requiring high safety integrity and easy visual diagnostics.
