440G-TZS21UPRH | Allen-Bradley TLS-Z GD2 Guard Locking Switch – 24V AC/DC

Allen-Bradley · HMIs & Displays

Description The Allen-Bradley 440G-TZS21UPRH is a TLS-Z GD2 Guard Locking Safety Switch designed for high-integrity machine guarding applications. Operating on 24V AC/DC, this power-to-release safety interlock provides secure guard locking with 2000 N (450 lb) holding force, ensuring that access doors remain locked until hazardous motion has stopped. Equipped with solid-state safety outputs and an 8-pin M12 quick-disconnect, it offers robust performance and simplified wiring for modern industrial safety systems.     Technical Specifications Condition New / Never Used Surplus Brand Allen-Bradley Series / Family 440G TLS-Z GD2 Part Number 440G-TZS21UPRH Product Type Guard Locking Safety Switch Model Type Power to Release Actuator Type Fully-Flex Safety Contacts 2 N.C.

PNP (0.2A max) – Lock Status Solenoid Voltage 24V AC/DC Holding Force 2000 N (450 lbs) Connection Type 8-Pin M12 (Micro) Terminal Type Plug-In QD Housing Material Plastic Enclosure Rating IP66, IP67 Standards / Approvals C-TICK, CCC, KC Mounting Panel / Guard Door Solenoid Contacts None (solid-state outputs only)       Information About 440G-TZS21UPRH The Allen-Bradley 440G-TZS21UPRH is part of the Guardmaster TLS-Z GD2 family, engineered for reliable access-guard locking on machinery where hazardous motion must be fully stopped before entry is allowed. 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. Key Features: Power-to-Release guard locking safety switch Fully-flex actuator compatibility for misaligned doors 24V AC/DC solenoid operation 2 N.C. PNP solid-state safety outputs 1 N.O. PNP auxiliary lock status output Heavy-duty 2000 N (450 lb) holding force 8-pin M12 quick-disconnect connection Plastic, corrosion-resistant housing High environmental protection: IP66, IP67 Ideal for guard doors, hatches, and machine access panels Suitable for Category 4 / PL e / SIL 3 system architectures (when used with appropriate safety controller) The M12 8-pin quick-disconnect reduces wiring time and simplifies replacement. With a 2000 N holding force and compliance with global safety standards, the 440G-TZS21UPRH is ideal for OEMs, integrators, and safety upgrades requiring reliable guard locking.
