Guard Locking Safety Interlock Switches
APPLICATION:
IDEM Guard Locking Interlock switches are designed to provide robust position interlock detection for moving guards and provide a lock mechanism
to keep the guard closed until the hazard has been removed.
They are Tongue operated and are designed to fit to the leading edge of sliding or hinged machine guards to provide positively operated switching
contacts and provide a tamper resistant, not easily defeatable key mechanism.
They are available in various materials and housing styles of provide completely flexibility of choice depending upon the application. Offered with
a choice of output circuits, LED diagnostics and various actuators to aid installation and maintain durability throughout the rigorous applications
associated with Factory Automation, Packaging, food Processing, Pharmaceutical and Petro-Chemical industries.
OPERATION:
The switch is rigidly mounted to the frame of the guard or machine. The actuator is fitted to the moving part (frame) of the guard and is aligned to the
switch entry aperture. The actuator profile is designed to match a cam mechanism within the switch head and provides a positively operated interlock
switch.
For Standard and RFID versions the actuator is inserted into the switch and the safety contacts close and allow the machine start circuit to be
enabled. When the solenoid receives the required signal the safety contacts are positively opened, the machine circuit is broken and the guard door
can be opened.
They can be used in combination with safety timers to provide a delay before allowing the guard to open (e.g. for machines which require run down).
For Power to Lock (P2L) versions the safety circuits can only close and switch locks when the power is applied to the solenoid.
They offer a choice of high specification plastic or die-cast housings and are sealed to IP67 and provide long term protection against moisture
ingress. For harsh applications like Food Processing, Pharmaceutical and Petro-Chemical Industries the Stainless Steel 316 range offers protection
up to IP69K for use in high pressure chemical cleaning or CIP/SIP applications.
