In the case of machine parks, locking devices and specialised switches are basic safeguards. They protect workers from injuries resulting from e.g. unintentional contact with a running machine. Electromagnetic interlock, in combination with the control part of the device, prevents safety guards from being opened before any unsafe machine condition is over.
Schmersal AZM 161 series safety switches – examples of application
This week, we would like to recommend to our customers AZM 161 electromagnetic interlocks from a renowned German manufacturer – Schmersal. This interlock is available in two versions: power to lock (also known as fail safe) or power to unlock (i.e. fail secure). Two models of actuators are designed to operate with these components: AZM 161-B1 used mainly for sliding and removable safety guards, and AZM 161-B6 for hinged guards.
