Slimline design for new solenoid interlock
10 December 2019
The AZM150 from the Schmersal Group is a new electromechanical solenoid interlock that is characterised by its slimline design and 1400 Newton interlocking force.
The AZM150 solenoid interlock can be combined with three different actuators for different installations: a straight actuator for sliding doors, an angled actuator for large revolving doors and a movable actuator for smaller, revolving doors.
One of the plus points of the interlock is the rotating actuator head which can be locked simply by putting the lid on rather than a screw fitting. The rotating actuator head has two feeder slots to enable a range of installation positions and approach options. This makes the interlock really flexible to use.
The AZM150 solenoid interlock is an electromechanical design which can be combined with high safety standards. The interlock comes with a low coding level as standard but is also available with an optional high coding level. The benefit for users: In accordance with ISO 14119, a higher coding requires fewer measures to prevent the bypassing of locking mechanisms, such as fitting out of range or in a concealed position.
Because of its space-saving design, the AZM150 is especially suited to small machines and to packaging machines and machine tools. The solenoid interlock is available in operating current and standby current variants. Schmersal Group says interlocks working on the standby current principles are preferred when the aim is to protect personnel from hazardous run-on movements. Interlocks working on the operating current principle are suitable for process safety, as, in the event of a fault, i.e. a power cut, they grant access to the hazardous area.
One of the practical features of the AZM150 is the fact that the interlock can simply be installed onto 40mm groove profiles using a mounting plate. In addition, it can be fitted with an emergency exit release or emergency unlock as an option.
If required, the AZM150 can be supplied with an optional lockout tag: this protects operating staff from being locked inside larger, walk-in systems and machines by mistake while they are performing servicing and repair work. To ensure protection, service personnel attach a padlock to the lockout tag used in the interlock when entering the hazard zone. This means the safety system door can no longer be closed and the machine is prevented from starting up unintentionally. Up to six padlocks can be attached to the lockout tag, meaning up to six people can enter the hazard zone at the same time.
