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.

Securely lock your protective gates with this solenoid interlock switch from Schmersal. Thanks to its fast maximum reaction time of 100ms, it quickly engages your safety measures to give you effective protection against machine hazards. The lock's high clamping force of 1500N prevents your guards from opening while machinery is active for reliable safety. It features individual RFID coding that only works with its compatible actuator (880-1735), reducing the risk of tampering.

• Complies with EN 60947 safety standards for low-voltage switchgear and controlgear
• Minimum mechanical lifespan of one million cycles for long-lasting performance
• IP69K rating for protection against dust and high-temperature, high-pressure water jets
• Compact size of 120 (length) x 87.5 (width) x 35mm (height) for installation in tight spaces

• Hazardous areas
• Food processing industry
• Packing lines
• Automotive industry

RFID switches like this one use coded radio waves to detect a paired actuator. This means that actuators without the correct coding won't work with this switch, reducing the risk of accidental switching and machine tampering.
