The AZM300 Solenoid Interlock Switch is significantly different from other switchgear offered on the market. Because of the innovative interlocking system in the form of a rotary Maltese cross, the interlock can be actuated from three sides, providing universal application possibilities. It can be used both on revolving doors with left-hand side and right-hand side hinges and on sliding doors.
No additional add-on parts such as a door stop or a latching element are required as they have been integrated in the interlock. The AZM 300 integrates another practical function, namely the adjustable latching force, i.e. the non-safety-related interlocking function when the safety guard is unlocked. Because of this feature, the interlocking system can be smoothly adjusted to suit individual requirements.
An integrated RFID sensor detects the identification and the coding of the actuator. Two different types of coding are available, a basic version and a uniquely coded version. In the basic version the sensor will accept any suitable target, whereas the uniquely coded version only reacts to an individually assigned target. The teaching procedure can be repeated an arbitrary number of times.

A solenoid interlock safety switch keeps a guard door locked while a machine is in operation, preventing personnel from accessing dangerous equipment. When the built-in contacts are activated by a magnetic force, this causes the machine to stop working and allows the door to open. You can use these types of safety switches on revolving doors, hinged doors and sliding doors for versatility.
