Guard lock

Guard lock

Electromechanical solenoid locking units prevent the opening of access or safety gates

Guard locks in the SAFEMASTER STS family combine our trusted mechanical principle with the advantages of electromechanical safety switches with a 2-channel locking function. Thanks to their lock monitoring features, they can be used to reliably protect both processes and personnel. Different coding levels, very high locking forces, and comprehensive diagnostic capabilities allow them to be used in almost all safety-relevant applications.

More information

Electromechanical safety switches with a solenoid locking unit secure that safety gates and – covers as well as other safe guards will remain closed, as long as there is a dangerous state or a risk of injury to persons. For example with safety applications like overrun movements of a machine, high temperatures or systems which are under high pressure (pneumatic, hydraulic etc.).
