Schmersal AZM 300 solenoid interlock

The Schmersal AZM 300 solenoid interlock has an innovative interlocking system in the form of a Maltese cross. The interlock can be actuated from three sides, which provides for universal application possibilities. Another advantage of this feature is that the user does not need any additional add-on parts such as a door stop or a latching element, considering that these functions have been integrated in the interlock.

The device integrates another practical function, namely the adjustable latching force, ie, 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.

The device also includes innovative electronics, with an integrated RFID sensor that detects the identification and the coding of the actuator. This means that the user can choose three different types of coding.

In the basic version, the sensor accepts any suitable target. A second - coded - version only reacts onto an individually assigned target. The teaching procedure can be repeated an arbitrary number of times. Finally, a third variant is available, which only accepts the target that was taught on the first activation.

The solenoid interlock meets the requirements of Cat 4, Performance Level e or Safety Integrity Level 3.

Because of its protection class IP69K, it is also suitable for use in hygiene-sensitive areas.
