Smallest interlock in the world

The AZM40 is the smallest electronic solenoid interlock in the world. Besides its extremely small housing it is distinguished by the 180° angle flexibility of the actuator. This makes it especially suitable for small safety doors and flaps. Despite its compact size, the AZM40 has an amazing interlocking force and a coding level of “high”.

Interlock AZM40, small but extremely strong

Schmersal added the AZM40 interlock to its family of electronic safety switches. It is distinguished by a small housing, adapted for fitting to standard 40 mm aluminum profiles without projecting.  This makes it suitable for small safety doors and flaps.

Thanks to the 180° angle flexibility of the actuator, the AZM40 is also suitable for flaps which do not close at 90° or those that open upwards to a 45° angle. This means the angle flexibility helps the interlock easily fit into compact spaces and those which are difficult to access. Special versions with individual coding ensure a coding level of “high” according to the requirements of DIN ISO 14119.
