Mechanical and non-contact coded safety switches for monitoring movable guards and safety gates, built to EN ISO 14119 tamper-protection requirements.

The mechanical variant is a safety switch for movable guards: mechanically coded actuators trip the switch the instant a guard is opened, meeting EN ISO 14119's protection-against-defeat requirements. The non-contact variant is the counterpart — a coded safety switch for safety gate monitoring, available in compact, slim, and large designs with multiple actuation directions and switching distances. For the highest safety category, combining the mechanical switch with a second switch from the same family reaches Performance Level e.

This switch trips as soon as a movable guard is opened, using mechanically coded actuators for tamper resistance.
Non-contact coding monitors safety gates flexibly, across multiple actuation directions and distances.
Pairing the mechanical switch with a second switch in the family reaches Performance Level e for the most demanding guarding requirements.
EN ISO 14119 sets out requirements for interlocking devices associated with guards, including protection against defeat, meaning making the switch hard to bypass or tamper with. Prazamana's safety switches are built to these protection-against-defeat requirements, and the mechanical type uses mechanically coded actuators for tamper resistance.
Yes. Safety switches are used to monitor movable guards and safety gates, which includes the hinge and sliding doors in Prazamana's Machine Guarding range. Where a gate must be locked closed until a hazard has stopped, a guard-locking interlock such as the Mechanical Lock accessory can be used. The right choice depends on the risk assessment.
A safety switch sends a signal to a safety relay or safety controller, which stops the hazardous movement when the guard is opened. Prazamana's range includes safety relays and a failsafe PLC controller for this purpose. Please share your machine details with the team so they can advise on the setup.
