Leading Manufacturer of Safety Interlock Switches and Machine Guard Safety Switch Devices for Automation and Process Safety

Solenoid Guard Locking Switch up to 3000N (KLT-SS)

The KLT-SS guard locking safety interlock features a hygienic, mirror polished 316 stainless steel body and a holding force of up to 3000N to keep medium to large guard doors closed until hazards have been removed. The KLT-SS has a low body profile with industry standard 73mm fixing centres, to enable easy retrofitting to new or existing guards.

  • Body Material: Mirror Polished 316 Grade Stainless Steel
  • Holding Force: F1Max 3000N (300Kg)
  • Actuation: Rotating head for 4 entry positions
  • Ingress Protection: IP69K
  • Conduit: 3 x M20 or ½” NPT (Quick Connect Available)

Note: Internal selector switch to be used as either power feed to LED 2 or as a voltage free auxiliary circuit to indicate the lock status.
