Eaton E50KL310 – Frequently Asked Questions

1) Will an Eaton E50KL lever fit any Eaton limit switch, or only certain heads?
The E50KL levers are made for side rotary heads in the Eaton E50 series. They clamp to the rotary shaft on the switch head to convert machine motion into switching action. If your E50 switch has a plunger, wobble stick, or top rotary head, this lever family is not the actuator for it.
2) Which E50 lever actuator styles can I order, and what are the part numbers?
Seven actuator styles are offered: offset inboard roller (E50KL24), roller mechanism with no roller (E50KL31), roller on reverse side (E50KL310), adjustable wide roller lever (E50KL37), spring rod (E50KL421), standard ball bearing roller (E50KL531), and adjustable ball bearing roller (E50KL539). Actuator style is the only thing you specify, so match it to how the cam or machine member strikes the lever.
3) Can I use this limit switch lever on a food plant washdown line?
Stainless steel construction is why this lever gets specified for washdown. The E50 lever carries NEMA 4X along with NEMA 1, 3, 3S, 4, 6, 6P, 13 and IP67, so it holds up to hose-down cleaning and corrosive atmospheres where a plated steel lever would rust at the roller pin.
4) Does the E50KL lever come with the limit switch, or do I buy the switch separately?
It's an accessory lever only. You get the actuating arm that mounts on the side rotary head, not the switch body, head, or contact block. For a new installation you order the E50 switch and head separately and add the lever style that suits the application.
5) Should I use a fixed roller lever or an adjustable one on a limit switch?
Fixed-length levers like the standard ball bearing roller (E50KL531) are the simpler choice when the cam-to-shaft distance is known and won't change. Adjustable versions, the adjustable wide roller lever (E50KL37) and adjustable ball bearing roller (E50KL539), let you slide the roller in or out to set the actuation radius during commissioning, which is what you want when the machine geometry isn't fixed yet or the trip point needs tuning in the field.
6) What temperature range can the Eaton E50 lever handle?
Rated 10 degrees F minimum to 200 degrees F maximum. That covers most indoor plant floors and hot process areas, but an unheated outdoor or freezer application that drops below 10 F is outside the rating.
7) When would I order the E50KL31 roller mechanism without a roller?
E50KL31 is the lever arm and roller mechanism supplied without the roller itself, so it's the pick when you are fitting your own roller material, or when you need the arm and already have the roller. If you want a complete ready-to-run assembly, order one of the styles that includes the roller, such as E50KL531.
8) What does the spring rod version of the E50 lever do that a roller lever doesn't?
The spring rod actuator (E50KL421) is a flexible wand rather than a roller arm. It trips from contact in multiple directions and tolerates a target that isn't travelling on a clean, repeatable cam path, which is how it gets used for detecting loose product or over-travel. A roller lever is the better choice when a cam strikes it consistently from one direction and you need a repeatable trip point.
9) My existing lever roller hits the machine frame on the wrong side. Which E50 lever fixes that?
Two styles solve clearance and approach-side problems: E50KL310 puts the roller on the reverse side of the arm, and E50KL24 is an offset inboard roller. Both shift where the roller sits relative to the arm so the cam can reach it without the arm fouling the frame or the switch body.
10) Is the Eaton E50 limit switch lever UL Listed and RoHS compliant?
Yes, the E50 stainless steel lever is UL Listed and RoHS Compliant, which is usually what a plant or institutional spec asks for on machine safety and automation components.
