Adjustable roller lever arm

The Eaton E50KL201SPL is an adjustable roller lever arm designed for limit switch applications. It fits E50AR16P and E50AR1 assemblies and suits machinery requiring precise position detection. The arm is built from stainless steel for durability in industrial environments. It is intended for maintenance engineers and machine builders configuring safety or control circuits.

Arm length range and roller specs

The arm length adjusts from 1.00 in to 3.75 in, giving flexibility for various actuation points. The nylon roller measures 0.75 in diameter by 0.32 in width and sits at the front position. Arm width is 0.75 in and depth is 4.6 in. This range covers many standard limit switch setups but will not reach extended travel requirements beyond 3.75 in.

Stainless steel arm and nylon roller

The stainless steel arm resists corrosion and mechanical wear in harsh shop conditions. The nylon roller reduces friction and noise during actuation, extending switch life. No additional hardware or software is bundled with this lever arm. Buyers needing a different roller material or a fixed-length arm must source a separate part.
