KL3-SS-Z-RR QC-M12 Guard Locking Safety Switch with RFID, OSSD, Rear Release and M12 Quick Connect
The KL3-SS-Z-RR QC M12 guard-locking RFID safety interlock with OSSD outputs features a robust 316 stainless steel enclosure with a mirror-polished finish for enhanced hygienic performance. 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 OSSD outputs allow up to 30 devices to be connected in series while maintaining a high level of functional safety. Integrated LEDs provide clear diagnostics for device status, including solenoid state, guard position, and input/output status. This device also includes a non-latching rear release mechanism, enabling the guard lock to be released quickly from inside the guarded area in an emergency.
The KL3-SS-Z-RR is suitable for applications requiring strict washdown procedures, including high-temperature, high-pressure washing and exposure to corrosive cleaning chemicals.
