B-LINE E50KL544 – Frequently Asked Questions
1) What kind of limit switch head does the E50KL544 lever mount to?
The E50KL544 is a lever for E50 series side rotary limit switch heads. It is not a switch body or a head on its own, just the actuating arm that clamps to a side rotary operating shaft. If your switch head is a top plunger, top roller, or wobble stick style, this lever won't mount to it.
2) What does a fork lever with both rollers on one side actually do on a conveyor or machine?
This actuator is a fork lever with both rollers mounted on the same side. A cam or passing object strikes one roller to rotate the switch shaft, and the second roller on the same side means the lever stays held or maintained in position rather than resetting the moment the cam clears. Use it where you need the switch to hold its state after actuation instead of spring-returning. If you want the lever to reset on its own after each pass, you want a single roller or standard roller lever head instead.
3) Can I use the B-Line E50KL544 lever in a washdown or outdoor location?
Yes. The E50 lever carries NEMA 1, 3, 3S, 4, 4X, 6, 6P, 13 and IP67 ratings, which covers rain, hosedown, dust, oil-laden atmospheres and temporary submersion. The 4X rating is the one that matters for corrosive or food-plant washdown areas. The overall enclosure protection still depends on the E50 switch body and head it is fitted to being rated the same.
4) I'm replacing a broken lever on an existing E50 limit switch. Do I need the whole switch?
No. E50KL544 is sold as a replacement lever accessory, so if the switch body and side rotary head are still good you can order just the lever and keep the existing wiring and enclosure in place. Match the actuator style you are replacing, fork lever with both rollers on one side, because swapping to a different lever type changes how the switch resets.
5) Will this limit switch lever hold up in a hot process area?
The lever is rated for 10 to 200 degrees F. That covers most oven-adjacent, boiler room and unheated outdoor industrial locations, but it rules out freezer and cold-storage applications below 10 degrees F. The lever body is metal, so there is no plastic arm to soften at the top of that range.
6) How much clearance do I need to swing the E50KL544 lever inside my machine guard?
The lever measures 2.87 in by 1.92 in by .62 in. Allow for the full 2.87 in reach plus the arc it sweeps as the cam rotates it, so lay out at least that radius of free space around the switch shaft before you bolt the switch to the frame.
7) What is the exact part number to order this B-Line lever by?
Order it as Eaton B-Line E50KL544. That single model number covers the lever; there are no finish or length options to specify. Full specifications are on the E50KL544 spec sheet linked from the product information.
