KLT-SS-RFID Guard Locking Safety Switch with RFID and M23 Quick Connect
The KLT-SS-RFID is a heavy-duty Type 4 guard-locking safety switch with integrated RFID technology. Its robust design provides a holding force of up to 3000 N, helping keep medium to large guard doors securely closed until hazards have been removed.
The integrated M23 connector reduces installation time, helps prevent wiring errors, and makes maintenance or replacement faster, simpler, and more reliable.
The KLT-SS-RFID is suitable for applications requiring strict washdown procedures, including high-temperature, high-pressure washing and exposure to corrosive cleaning chemicals.
