by Allen-Bradley

OverviewThe Allen-Bradley 440G-T27171 TLS-1 GD2 Guard Locking Switch is a critical safety component designed for rigorous industrial environments. This switch is specifically engineered for machinery guarding applications where a "power-to-release" mechanism is required. It ensures hazardous equipment remains securely locked until electrical power is intentionally supplied to disengage the guard. Operating reliably on a 24V AC/DC power input, the 440G-T27171 integrates advanced safety features to protect personnel and enhance operational efficiency. Its substantial holding force and adaptable actuator make it suitable for a wide range of industrial machinery, providing peace of mind and strict adherence to safety mandates.Key Features Power to Release Mechanism: Guarantees the guard stays firmly locked, releasing only when power is applied, thereby preventing accidental access during machine operation. 24V AC/DC Solenoid: Delivers dependable and efficient actuation, compatible with common industrial power systems. Advanced Safety Contact Setup: Includes 2 Normally Closed (NC) safety contacts for fail-safe operation, along with 1 Normally Open (NO) auxiliary contact for status monitoring and 1 NC / 1 NO contact for the solenoid, offering comprehensive control versatility. Fully-Flex Actuator: Provides exceptional flexibility for mounting and alignment, simplifying installation even when guards or doors are slightly misaligned. High Holding Capacity: Boasts an impressive 2000N (450 lbs) holding force, securely locking guards and preventing unauthorized entry into dangerous areas. Durable Construction: Built to withstand demanding industrial conditions, ensuring long-term use and consistent performance in harsh environments. Integrated Conduit Access: Features a 1/2" NPT adapter for straightforward and secure wiring integration, reducing installation time and complexity. Technical Specifications Model: 440G-T27171 Series: TLS-1 GD2 Operating Voltage: 24V AC/DC Safety Contacts: 2 NC (Normally Closed) Auxiliary Contacts: 1 NO (Normally Open) Solenoid Contacts: 1 NC / 1 NO Holding Force: 2000N (450 lbs) Actuator Type: Fully-Flex Conduit Entry: 1/2 inch NPT Adapter Mounting: Panel or Machine Surface Applications Machine Guarding & Safety Systems: Prevents unauthorized personnel from accessing dangerous machinery during operation, crucial for compliance and worker safety. Automated Manufacturing & Robotics: Ensures controlled and secure access to robotic work cells and automated lines, enhancing operational safety and efficiency. Packaging & Material Handling Equipment: Ideal for securing guards on conveyors, palletizers, and other material handling systems, maintaining a safe working environment.
