SQUARE D 9007C Roller Lever Arm Limit Switch

Roller Lever Arm for 9007AW Switches

This zinc actuator arm fits Square D 9007AW limit switches and provides mechanical actuation in industrial control circuits. The outside-offset roller engages moving parts to trigger the switch mechanism reliably. It is suited for maintenance engineers and panel builders replacing worn lever arms on existing installations. The arm length measures 2 in and the tapered width allows clearance in tight enclosures.

Steel Roller and Zinc Arm Construction

The 0.75 in diameter steel roller reduces friction and wear during repeated actuation cycles compared to plastic alternatives. Zinc arm material resists corrosion in humid or outdoor environments where the switch operates. The 0.25 in roller width and 0.31 in arm depth combine to keep the assembly compact while maintaining structural rigidity. These material choices extend service life in conveyor and machine-tool applications.

Mechanical Interface Constraints

The arm mounts only to compatible 9007AW switch bodies and cannot be adapted to other brands or series without modification. The outside-offset roller position fixes the actuation travel path, so the target cam or dog must align precisely with this geometry. The standard roller type suits linear or rotary motion but may not suit high-speed or high-side-load applications where specialised rollers are required.
