The Allen-Bradley 440G-L07264 is a high-security TLS-ZR-GD2 Guard Locking Switch. This is a “Power-to-Release” solenoid-operated safety interlock, which means the guard remains locked even if power is lostÑa critical feature for machines with high inertia (like large flywheels or saws) that don’t stop instantly.
What makes the TLS-Z series special is that it incorporates RFID technology for the actuator, giving it a high level of tamper resistance (PLe/Cat 4) compared to older mechanical-only tongue switches.
