E51DT1 Cutler Hammer E51 Inductive Proximity Sensor Head - Shielded, Top Sensing, 0.51 in Range

E51DT1 Cutler Hammer E51 Inductive Proximity Sensor Head - Shielded, Top Sensing, 0.51 in Range

Got a dead prox head on an E51 limit switch style sensor? The E51DT1 drops onto any Eaton E51 body in minutes. Back out the captive screws, pull the old head, seat this one, and you're running again without touching the machine wiring. It's a shielded, top sensing inductive head with a 0.51 in (13 mm) range, so you can mount it flush in a metal bracket and it will still pick up your target every cycle.

A selector switch right on the head flips the output between normally open and normally closed, so one part on the truck covers both wiring schemes. Sealing runs NEMA 3, 3S, 4, 4X, 6, 6P, 12, and 13 plus IP67, which keeps it alive through washdown, coolant spray, and outdoor duty. UL Listed and CSA Certified when the inspector comes around.

Common Applications

• Swapping out failed heads on existing E51 sensor installs
• Retrofitting mechanical limit switches to non-contact sensing
• Part presence and position detection on production machinery
• Conveyors, packaging lines, and material handling gear
• Washdown areas and wet locations where NEMA 4X sealing matters

Key Features

• Drop-in head replacement: Mounts to any E51 Series body with captive screws, no rewiring needed.
• Shielded sensing face: Flush-mount it in metal without nuisance trips from the surrounding bracket.
• 0.51 in range: Solid 13 mm nominal reach on metallic targets at standard frequency.
• Top sensing: Face is on top of the head, ideal where the target passes overhead.
• NO/NC selector: Set the output on the spot to match the circuit you're wiring into.
• Tough sealing: IP67 and NEMA 4X keep water, dust, and washdown chemicals out.

FAQ

Is the E51DT1 a complete sensor?
No, it's the head only. You mount it on an E51 body, which handles the supply voltage and output connection.

Will it fit my existing E51 body?
Yes. Heads across the E51 platform are modular and secure to any E51 Series body with captive screws.

Can I flush-mount this head in metal?
You can. The shielded design keeps the field at the face, so surrounding metal won't trip it.

How do I change the output from NO to NC?
Flip the selector switch built into the head. No jumpers or special tools required.

Is it rated for washdown?
Yes, with NEMA 4X and IP67 sealing it handles hose-down cleaning and wet environments.
