MK-Safe Key Exchange range

The Proton advance solenoid interlock has been designed for use on machines where hazardous
conditions persist even after the machine has been switched off. The robust design and heavyduty
solenoid can withstand up to 2000N hold force and energise under a lateral load. The internal
specifications meet the requirements for CAT4, SIL3 and has been designed to maintain PL-e even
when connected to a safety relay or PLC.

The Proton R-Type offers protection against manipulation, interference and defeat making them ideal for use in high risk applications. Mechan’s unique coding technology allows for 4 billion possible codes. Should either part be lost or damaged, the teach-in facility allows for unlimited re-teaching.

The O-Type range combines 40+ years of experience designing and manufacturing machine
guard safety products with the latest in safety technology. There unique design means 30 O-Type
switches can be connected in series maintaining PL-e status.
O-Type safety switches include two LEDs for indication. They are able to provide visual
diagnostics for ALL states of the device. This means the user can easily fault find without needing
to access the control panel.
The O-Type safety switches are available with a feature called EDM (external device monitoring,
this means the outputs can be used to monitor the state of contactors without the need for a safety
control unit.
