Product description

The Allen-Bradley 440G-T27134 is a Guardmaster safety interlock switch featuring a spring actuator. This design is suitable for applications where a spring-loaded mechanism is needed to ensure the safety switch returns to its de-energized state when the guard is open. Built for industrial resilience.

This safety switch is crucial for protecting personnel by ensuring machinery remains off when access panels are not securely closed. It's commonly used in manufacturing, packaging, and automation industries, especially on guards or doors that require a positive spring return action for safety compliance.

Stanlo Automation, a veteran-owned distributor of industrial surplus, provides the 440G-T27134. We offer reliable, quality components with fast shipping, supporting your facility's safety protocols and minimizing costly downtime.
