Limit Switch Lever Arm

The SQUARE D 9007DA1 limit switch lever arm is designed for industrial electrical controls and automation systems. It functions as an actuator with a standard roller for precise mechanical positioning. This component suits maintenance engineers and panel builders who need reliable limit-switch actuation. Buyers requiring a different arm length or roller diameter should select an alternative model.

Thermals Noise Power Draw

As a passive mechanical lever arm, this part generates no heat, audible noise or electrical power draw during operation. Its zinc arm and steel roller withstand repeated physical contact without thermal buildup. The component simply transmits force to the attached limit switch body. Installers should verify that the switch housing itself meets the application’s environmental ratings.

Bundled Accessories Software

The lever arm ships as a single replacement actuator; no mounting hardware, wiring adapters or configuration software are included. Users must supply their own fasteners and connect the arm to a compatible 9007AW or 9007C switch body. The tapered arm width and 0.31 in depth allow straightforward alignment with existing brackets.

Questions about this item

How do I install the 9007DA1 lever arm on a 9007AW switch body?

Align the arm's tapered zinc body with the rotary shaft on the 9007AW or 9007C switch, then secure the set screw; the common error is leaving the 0.63 in steel roller in the default outside-offset position when the application requires inside offset.

What maintenance will the roller and arm need over time?

The 0.63 in diameter steel roller and 0.25 in width should be inspected for flat spots or bearing drag; the zinc arm rarely wears, but replace the roller if rotation becomes stiff or the 0.31 in arm depth shows cracking at the pivot.

What is the first limit reached during continuous high-cycle operation?

The 2.5 in lever arm amplifies inertia, so the roller bearing typically reaches its speed limit before the zinc arm yields; sustained rapid actuation will heat the 0.63 in steel roller and widen the 0.25 in contact patch first.
