Allen-Bradley 440G-T27171

Overview

The Allen-Bradley 440G-T27171 TLS-1 GD2 Guard Locking Switch is an essential safety component engineered for demanding industrial environments. Designed specifically for machine guarding applications requiring a "power-to-release" mechanism, this robust switch ensures that hazardous machinery remains securely locked until power is intentionally applied to disengage the guard. Operating flawlessly on a 24V AC/DC power supply, the 440G-T27171 incorporates advanced safety features to protect personnel and optimize operational efficiency. Its high holding force and versatile actuator make it ideal for a wide array of industrial machinery, providing peace of mind and strict adherence to safety regulations.

Key Features
