Eaton E47 Enclosed Precision Limit Switch, Die-Cast Aluminum, 1-SPDT

The Eaton E47 Enclosed Precision Limit Switch is a rugged, die-cast aluminum limit switch built for demanding industrial position-sensing and machine-control applications. Featuring a 1-SPDT (Form C) contact configuration, screw terminal connections, and an operating speed range of 0.01 mm/s to 1 m/s, the E47 delivers precise, repeatable actuation feedback. It carries a contact rating of 15A at 250 Vac and 6A at 30 Vdc, and is housed in a NEMA 1 enclosure for indoor control-panel and machine-mounting environments.

Key Features

  • Durable Construction: Die-cast aluminum enclosure resists impact and mechanical stress in industrial settings.
  • Connection Type: Screw terminal connections simplify field wiring and maintenance.
  • Contact Configuration: 1-SPDT (Form C) contact arrangement supports both normally open and normally closed circuit switching.
  • Contact Rating: Rated 15A at 250 Vac and 6A at 30 Vdc for reliable switching performance.
  • Operating Speed: Actuates across a wide range of 0.01 mm/s to 1 m/s, suiting both slow and fast-moving machine elements.
  • Compact Dimensions: 1 in product width and 3.39 in product length/depth for space-conscious panel and machine mounting.
  • Environmental Rating: NEMA 1 enclosure rating for general-purpose indoor use.
  • Operating Temperature Range: Rated for use from -13 °F to 176 °F.

Eaton E47BLS05 – Frequently Asked Questions

1) Which actuator styles does the Eaton E47BLS limit switch come in?
Four actuator heads are offered on the E47BLS: a plain plunger (E47BLS05), a booted plunger (E47BLS06), a roller plunger (E47BLS07), and a booted one-way roller (E47BLS35). Pick the plain plunger for a cam or dog hitting the switch straight on, the roller plunger where the target slides across the actuator instead of pushing into it, and the one-way roller where you only want actuation in one direction of travel. The booted versions add a seal over the plunger where dust or chips are a concern.
2) Can the Eaton E47 limit switch be mounted outdoors or in a washdown area?
No. The E47 carries a NEMA 1 enclosure rating, which is general-purpose indoor protection against incidental contact and falling dirt only. It offers no rated protection against rain, hose-down, or liquid ingress, so keep it inside a machine guard, control panel, or indoor plant environment. For outdoor or washdown duty you need a switch with a NEMA 4 or 4X rated housing instead.
3) Does the Eaton E47 give both a normally open and a normally closed contact?
Yes. The contact arrangement is 1-SPDT, also called Form C, which means one common terminal with both a normally open and a normally closed contact off it. That lets you run an end-of-travel stop on the NC side and a position indicator or PLC input on the NO side from the same switch. Wiring lands on screw terminals.
4) How much room do I need to mount an Eaton E47 limit switch on a machine frame?
The body measures 1 inch by 3.39 inches (width and length/depth as published), so it drops into tight spots alongside a track or conveyor frame. Allow extra clearance beyond that for the actuator head travel and for the screw terminal wiring entry.
5) Will this limit switch work in an unheated warehouse in winter or near a hot process?
The E47 is rated from -13 degrees F to 176 degrees F, which covers an unheated northern warehouse or dock as well as most warm plant areas near ovens or drives. Anything below -13 F or above 176 F at the switch body is outside the rating.
6) Is the Eaton E47 fast enough for a high-speed conveyor, and will it still trip on a slow-moving actuator?
Operating speed range is 0.01 mm/s up to 1 m/s, so it covers both ends: a creeping indexing table at a fraction of a millimeter per second and a conveyor flight moving a meter per second. That wide range is why the same switch gets used for slow positioning and for fast end-of-travel detection.
7) Is a plastic-bodied limit switch a substitute for the Eaton E47 on a production line?
Not where impact is a risk. The E47 uses a die-cast aluminum enclosure, which takes knocks from pallets, forklifts, and misaligned parts that would crack a thermoplastic housing. If the switch sits where nothing can strike it, a plastic body is fine; if it is exposed on a machine frame or near material handling, stay with the metal housing.
8) Do I need ferrules or crimp lugs to wire the Eaton E47?
No special termination is required. The E47 uses screw terminals, so stripped conductors land directly under the screws, which keeps field wiring and later troubleshooting simple. Ferrules are optional good practice on stranded wire but nothing on the switch demands them.
