Allen-Bradley 440T-MSRUE11RF Industrial Servo Motor

The Allen-Bradley 440T-MSRUE11RF Trapped Key Interlock Solenoid Release Unit is a 24 V DC safety interlock module designed to release a trapped key only when the guarding circuit is in a safe state. It provides two normally open and two normally closed contacts rated at 20 A, enabling robust interlock and associated circuit wiring. Built for industrial environments, the unit carries an IP66 enclosure rating and operates in ambient temperatures from 0 to 40 °C. Its footprint is about 150 mm tall by 140 mm long, and it supports a primary code of RF as part of the 440T trapped-key release family. Typical applications include safeguarding doors and access panels on machinery and integrating with Rockwell Automation Guardmaster safety systems to ensure compliant, verifiable access control in automated cells.
