Eaton NEMA Heavy-Duty Plug-In Limit Switch, Switch Body Only, Die Cast Zinc

The Eaton E50 Series NEMA heavy-duty plug-in limit switch (switch body only) is built for demanding industrial control and safety-interlock applications. Housed in a die cast zinc enclosure measuring 1.54 in wide, 3.14 in deep, and 1.73 in tall, this switch body delivers a contact rating of 10A at 240 Vac continuous and 1A at 250 Vdc with a 1 NO-1 NC contact configuration. Rated for NEMA 1, 3, 3S, 4, 4X, 6, 6P, 13 and IP67 environments, it is UL Listed and RoHS Compliant, making it well suited for exposed, washdown, or corrosive-duty machine control installations.

Key Features

  • Compact Dimensions: Product width 1.54 in, length/depth 3.14 in, and height 1.73 in for space-constrained control panel and machine mounting.
  • Durable Construction: Die cast zinc enclosure material provides rugged mechanical protection for heavy-duty industrial service.
  • Switch Body Only: Eaton E50 Series plug-in design allows the switch body to be paired with compatible operating heads for flexible actuation setups.

Eaton E50SN – Frequently Asked Questions

1) Does the Eaton E50SN limit switch come with an operating head, or do I need to order one separately?
The E50SN is the switch body only. It's a plug-in design, so you pick the operating head (roller lever, plunger, wobble stick, etc.) separately and plug it onto this body. Ordering the body alone gets you the contact block and enclosure, not a complete actuating switch, so budget a head on the same order or the switch will not do anything on the machine.
2) Can an Eaton E50 limit switch body be used in a washdown or outdoor wet location?
Yes. The E50SN body carries NEMA 1, 3, 3S, 4, 4X, 6, 6P and 13 plus IP67, which covers indoor, outdoor, hosedown, temporary submersion and corrosive duty. The 4X rating is the one that matters for food plants and chemical areas, and the die cast zinc housing handles the mechanical abuse. Note the sealing of the finished assembly also depends on the operating head you plug in.
3) Will a 10A limit switch directly switch a motor, or do I need a contactor?
Use it as a pilot-duty device. The E50SN is rated 10 A continuous at 240 Vac and only 1 A at 250 Vdc, which is sized for switching a contactor coil, relay or PLC input, not for carrying motor load current. Anything beyond that goes through a starter or contactor that the limit switch commands.
4) What contact arrangement does the Eaton E50SN have, and can I use it for both a stop signal and a run signal?
It's a 1 NO-1 NC arrangement, so you get one normally open and one normally closed contact from the single body. That lets you break an interlock circuit and make an indication or PLC input off the same actuation. If you need two independent circuits of the same type, or more than two contacts, this body won't do it.
5) Will this Eaton limit switch hold up in an unheated warehouse or a hot process area?
Operating range is 14 to 201 degrees F. That covers an unheated building in most climates and hot areas near ovens or dryers, but it is not a freezer-rated device. A walk-in cooler at 35 F is fine; a blast freezer below 14 F is outside the rating.
6) How much space do I need to mount an Eaton E50SN switch body on a machine frame?
The body measures 1.54 in wide, 3.14 in long/deep and 1.73 in high. Allow clearance beyond that for the operating head on the plug-in face and for the conduit entry and wiring bend radius, since those dimensions are the body alone.
7) Is the Eaton E50 limit switch UL Listed and RoHS compliant for a spec job?
Both. The E50SN is UL Listed and RoHS Compliant, which is what most industrial and institutional specs ask for on machine control devices. Pair that with the NEMA 4X and IP67 ratings when the submittal calls for a washdown or corrosive-location sensing device.
8) Why choose a plug-in limit switch body instead of a one-piece limit switch?
Maintenance. With the E50 plug-in arrangement, a damaged actuator head comes off and a new one goes on without pulling the wiring out of the body, and one stocked body covers roller lever, plunger or rod applications depending on the head. A one-piece switch means rewiring every time the actuator gets sheared off by a load. If you standardize a plant on E50 bodies, your spares shelf gets smaller.
