As a Power-to-Release model, the solenoid remains energized to unlock the guard, ensuring fail-safe operation in the event of a power loss. With 2 N.C. PNP safety outputs and 1 N.O. PNP auxiliary output, this switch provides advanced, solid-state signaling for safety relays, safety controllers, and PLCs. The auxiliary output delivers real-time lock status feedback to improve diagnostics and minimize downtime. The switch supports a fully-flex actuator, accommodating misalignment or vibration at the guard door—common in industrial environments. Rated IP66 and IP67, the TLS-Z GD2 withstands washdown, dust, and harsh conditions. The plastic housing provides corrosion resistance and long service life.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePower-to-Release guard locking safety switch\u003c\/li\u003e\n\u003cli\u003eFully-flex actuator compatibility for misaligned doors\u003c\/li\u003e\n\u003cli\u003e24V AC\/DC solenoid operation\u003c\/li\u003e\n\u003cli\u003e2 N.C.
