Eaton E50KL355 Cutler-Hammer Limit Switch Arm, Roller, 1.5 in Arm Length

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.
