Eaton E50KL537 Limit Switch Arm

The Eaton E50KL537 is an adjustable roller lever arm designed for E50 series limit switches. It connects to the E50AR16P or E50AR1 actuator heads to detect mechanical position. The arm length adjusts from 1.00 in to 3.75 in for flexible mounting. Both the arm and the 0.75 in diameter roller are made of nylon.

Installers needing adjustable reach

Maintenance technicians and machine builders who need a variable lever length for position sensing will find this arm suitable. It fits the specific E50 actuator models listed in the specifications. Operations requiring metal rollers, different roller widths, or compatibility with other switch series should select a different arm.

Nylon construction under continuous cycling

The nylon arm and roller resist corrosion and reduce wear on the contacted surface during repeated actuation. The material absorbs impact without deforming under normal industrial cycles. The 4.6 in arm depth provides a rigid structure that maintains alignment during sustained operation.

Questions about this item

Will the E50KL537 lever arm fit my existing E50AR16P limit switch body?

Yes, the E50KL537 is designed for use with the E50AR16P switch body, mounting directly to the actuator shaft as the designated adjustable roller lever.

Does the 0.75 in roller diameter match the travel cam on my older machine?

The roller measures 0.75 in diameter by 1 in width, so it will engage any cam profile built for those dimensions regardless of machine age.

How can I verify the arm moves through its full 1.00 to 3.75 in range after installation?

Loosen the adjustment clamp, slide the roller to each extreme, retighten, then actuate the switch by hand to confirm positive contact at both the 1.00 in and 3.75 in positions.
