Information About 440G-T27121
The 440G-T27121 is part of the Allen-Bradley Guardmaster TLS-GD2 safety interlock switch family. It features a compact plastic housing with an IP67 rating, engineered to withstand harsh industrial environments and frequent machine operation. The switch integrates directly into safety control systems using standard M20 conduit cable entry and supports common AC and DC control voltages. It is typically used on machine guards, access doors, and protective enclosures where controlled locking and monitored access are required to support functional safety systems.
Key Features:
- Guard Locking Function: Solenoid-operated locking prevents guard opening during hazardous motion.
- 24V AC/DC Supply: Compatible with standard industrial control power systems.
- Safety Contacts: Two normally closed contacts for safety-rated monitoring circuits.
- Auxiliary Contact: One normally open contact for status or control feedback.
- High Holding Force: Provides up to 2000 N (450 lb) clamping force for secure guard retention.
- IP67 Protection: Sealed housing resists dust and water ingress in industrial environments.
- M20 Cable Entry: Metric conduit connection supports straightforward wiring installation.
- Actuator-Free Design: Allows selection of an actuator based on application requirements.
The 440G-T27121 delivers the reliability and precision required for guard locking and safety interlock control in industrial machinery applications.
