The KLT-SS Series Guard Locking switch is a tongue type safety interlock switch incorporating traditional mechanical anti-tamper tongue technology utilising IDEM Safety Switched patented cam system.
They interlock and hold closed guard doors to protect operators from moving or hazardous machinery. They are particularly suited to where a high degree of anti-tamper technology is required to prevent accidental or deliberate atttempts to by-pass the interlock.
The KLT-SS Solenoid Locking Switch has a mirror polished Stainless Steel 316 body design and have been developed with a maximum holding force of 2000N to keep medium to large guard doors closed until hazards have been removed.
IP69K enclosure protection is maintained by a double seal lid gasket design and metal fixings.
The KLT-SS has a low profile and fixing holes are on an industry standard 73mm centre to enable easy retrofitting to new or existing guards (or where extra anti-tamper is required).
The head has been designed to allow rotation to provide up to 4 actuator entry positions.
