Overview
The Allen-Bradley 440T-AKEYE11A is a ProSafe trapped key replacement key designed for Series A interlock sequences. Replacement keys must be ordered separately when not provided by a previous sequential trapped key. This part is essential for maintaining safety interlock sequences in industrial machinery, guard doors, and access control systems. The 440T-AKEYE11A integrates with the broader Guardmaster ProSafe safety product family to enable controlled, sequential access to hazardous areas.
Key Features
- ProSafe-certified replacement key for Series A interlock code barrels
- Only Prosafe products carry the prestigious BG mark, a sign of safety independently tested by the German Berufsgenossenschaf
- Compatible with trapped key interlock sequences for multi-step safety protocols
- Manufactured by Rockwell Automation to exacting safety standards
- Field-proven in manufacturing, packaging, food processing, and automation environments
Technical Specifications
The 440T-AKEYE11A is a replacement key component engineered for access to hazardous areas only when an appropriate key is inserted into the interlock. As a passive mechanical component, this key does not carry electrical ratings but interfaces with ProSafe interlock switch code barrels. The key is cut to Series A specifications and must match the corresponding interlock barrel code (A, AA, B, CC, etc.) for proper operation.
Typical Applications
- Trapped key bolt interlocks for electrical isolation of machinery and preventing access through gates
- Electrical isolation of machinery to improve safe access and teach boxes in robot cells
- Access interlocks with lever or rod actuation connected to chain for preventing access through gates
- Safety interlock sequences requiring sequential key removal and insertion
- Guard door and hatch locking in industrial equipment
- Valve operation access control in compressed air and hydraulic systems
