Schmersal AZM40

Small Solenoid Interlock For Machine Guard Frames

July 2, 2021
Schmersal device integrates RFID sensor.

The AZM40 is the smallest electronic solenoid interlock available, with dimensions of just 1.5 in. × 4.75 in. × 0.75 in. (119.5 × 40 × 20 mm). It is designed to fit standard extruded profiles typically used in machine guard frames. It features a symmetrical housing and actuator approach of 180 deg., offering mounting flexibility on hinged or sliding guards which do not close at 90 deg. or those that open upwards to a 45-deg. angle.

The solenoid is strong for its size, offering 2,000 N locking force and 40 N latching. There is also an integrated RFID sensor, which offers the option of individually coding the actuators for enhanced tamper resistance. Models are available for guard locking or process protection applications. The internal monitoring means that this interlock meets the highest safety levels of PLe to ISO 13849 or SIL 3 to IEC 61508.
