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

Guard Locking Safety Switch with RFID up to 3000N (KLTM-RFID)

The KLTM-RFID guard locking safety interlock with RFID features a low profile body and with industry standard 73mm fixing centre, to enable easy retrofitting to new or existing guards. The robust design allows for a holding force of up to 3000N to keep medium to large guard doors closed until the hazard/s have been removed.

  • Body Material: Red Painted Die-Cast
    Head Material: Mirror Polished 316 Stainless Steel
  • Ingress Protection: IP67
  • RFID Coding: Unique (can be retaught if lost or damaged)
  • Safety Configuration: 4 N/C Safety Outputs and 2 N/O Auxiliary Outputs
