Eaton E50KL31 Limit Switch Arm

The Eaton E50KL31 is a stainless steel lever arm with an adjustable roller actuator designed for E50 series limit switches. It suits maintenance engineers and OEM integrators who need a replacement or configurable actuator for existing E50AR16P or E50AR1 switch bodies in industrial automation.

Upgrades from fixed or worn levers

This arm replaces fixed-length or damaged levers on compatible E50 switch bodies. The jump is worth it when the application demands an adjustable arm length between 0.50 in and 3.25 in with a 1.5 in roller diameter to match specific cam or target engagement profiles.

Mechanical interface constraints

The arm mounts only to E50AR16P or E50AR1 switch bodies using the manufacturer's designated mounting pattern. It cannot be used with other brands or switch series. The 0.75 in roller width and 4.6 in arm depth define the physical envelope; the actuator travel and force ratings are governed entirely by the host switch body specifications.
