Allen-Bradley 800T-J631A8 Keyed Cylinder Lock

Allen-Bradley 800T-J631A8 is a 30.5 mm diameter, 3-position cylinder-locking operator in the 800T family, designed as a keyed selector switch for control panels. It uses the D018 key code and provides key removal in the center position, enabling security while allowing left, center, and right detents to be reached with one key. The unit is rated Type 4/13 for harsh environments, and it employs a spring-return-from-both mechanism that returns to center when released from either outer position. The 800T-J631A8 offers a standard KB7 cam and a contact arrangement of 1 normally open and 1 normally closed, suitable for simple control-circuit signaling and interlocking tasks. This configuration—3 positions, center-key lock, and keyed removal—helps ensure only authorized operators can cycle to specific states, making it appropriate for motor-start sequences, selector logic, and process-control interlocks in industrial equipment.
