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.

This solenoid interlock switch from Schmersal enhances safety in your industrial workplace. It keeps doors, guards and gates shut when machinery is running, which helps to prevent damage to machines and offers a high level of protection for personnel. It has one auxiliary contact and two safety contacts that connect to the power supply. The unit only requires 24V DC (direct current) for operation, ensuring it doesn't put excess strain on your power source. It fits onto hinged doors, aluminium profiles and fencing for versatile use.

• IP69K (ingress protection) rating ensures the switch is protected against dust and high-pressure, high-temperature water jets for use in areas that require frequent cleaning
• Glass fibre-reinforced thermoplastic enclosure for protection against impact and shock in heavy-duty applications
• Silver contact material prevents rust and ensures good conductivity for a reliable connection
• Screw connection keeps the switch securely fixed in place

• Metal works
• Water treatment plants
• Timber yards
• Manufacturing lines

This solenoid interlock switch has an approximate mechanical lifespan of two million operations for long-lasting use.
