Eaton E50KL355 Limit Switch Arm

This Eaton E50KL355 limit switch arm is a replacement actuator designed for industrial electrical controls and automation systems. It fits the E50AR16P and E50AR1 switch bodies, providing a standard roller actuator for position sensing applications. The arm is constructed from metal for durability in demanding environments.

Actuator travel and roller dimensions

The arm length is fixed at 1.5 in with a front-mounted roller measuring 0.75 in diameter and 0.32 in width. These physical dimensions determine the mechanical travel and actuation point, so the switch body and mounting position must accommodate this exact geometry. No adjustment of the roller position or arm length is possible on this model.

1.5 in arm length for E50AR compatibility

The 1.5 in arm length is the critical specification that decides fitment with the E50AR16P and E50AR1 switch bodies. Buyers needing a different lever length or a rollerless actuator cannot use this part and must select an alternative arm assembly.

Questions about this item

Which arm length and roller size should I select for my E50AR16P switch?

This lever arm is 1.5 in long with a 0.75 in diameter roller that is 0.32 in wide, designed to fit the E50AR16P mounting pattern.

How does the 1.5 in arm length affect actuation travel in my machine?

The 1.5 in metal arm positions the front-mounted roller 2.22 in deep from the switch body, giving a defined lever ratio for consistent trip points.

What mounting standard does the E50KL355 follow and what does it limit?

It mounts directly to Eaton E50 series limit switches, fixing the roller at a 0.75 in diameter and 0.32 in width to standardise actuation force.
