Eaton E50KW3 – Frequently Asked Questions

1) Will the Eaton E50 lever operator fit any limit switch, or only side rotary types?
The E50K operators are built for Eaton E50 side rotary limit switches only. The lever mounts on the switch's operating shaft and rotates it to actuate the contacts. If your switch is a plunger, top push, or in-line body style, this lever will not mount to it.
2) What actuator styles does the Eaton E50K operator come in?
Six actuator styles cover the range: standard lever (E50KL203, E50KL27, E50KL340, E50KL533, E50KL542, E50KL543), adjustable rod (E50KL202), adjustable roller (E50KL598), plain rod (E50KW3), wobble stick (E50KW2), and wobble with coil spring (E50KW4). Rod and wobble types actuate from any direction, which suits random or off-axis target approach. Roller levers suit a repeatable cam or moving carriage that strikes from one side.
3) Can I replace just the lever on my Eaton limit switch instead of the whole switch?
Yes, that is exactly what these are. The E50K operators are replacement lever accessories for E50 side rotary switches, so a bent or worn arm can be swapped on the shaft without pulling the switch body or disturbing the wiring in the circuit.
4) Which E50K roller should I use on a high cycle conveyor?
E50KL542 uses a steel ball bearing roller, which is the one to pick where the arm gets struck constantly and side loading is real. E50KL543 uses a Nylatron roller instead, quieter and non-marring against a painted or finished target. Both are aluminum lever bodies.
5) What ambient temperature range are the Eaton E50 lever operators rated for?
Minus 40 F to 201 F. That covers unheated warehouses, outdoor conveyor lines, and cold storage, as well as hot process areas. For cold or outdoor use the nylon-bodied rod and wobble styles and the aluminum lever styles are both rated to the same range.
6) Are the Eaton E50K lever operators UL Listed and RoHS compliant?
Both. The E50K operators are UL Listed and RoHS compliant, which is what a plant or institutional specifier usually needs on file before a sensing component goes into a machine safety or interlock circuit.
7) What is the difference between the nylon and aluminum Eaton E50K operators?
The rod, wobble, adjustable rod, and adjustable roller styles (E50KL202, E50KL598, E50KW2, E50KW3, E50KW4) are nylon. The fixed lever styles are aluminum, with E50KL203 using a die cast zinc lever, E50KL340 an aluminum lever, and E50KL533 a nylon covered steel rod. Nylon bodies are non-marring and corrosion free; the metal levers take repeated impact from a hard cam.
8) Why choose an adjustable rod or adjustable roller operator over a fixed lever?
Adjustable styles let you set the effective arm length on site, so you can tune where the target makes contact without moving the switch or re-machining a bracket. E50KL202 is the adjustable rod and E50KL598 is the adjustable roller. Pick a fixed lever when the trip point is already established and you want one less thing to drift out of adjustment.
