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

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

Trying to track down the right replacement part for an older Eaton or Cutler Hammer sensor on your equipment? If the sensor on your machine has a removable top section from the E51 family, the E51DT1 may be exactly what you need. It is an inductive proximity sensor head, meaning it detects metal objects that come near it without any physical contact, at distances up to 0.51 in (about 13 mm).

Keep in mind this part is the head portion only. It attaches to an E51 Series sensor body, which is the lower section that contains the wiring terminals and electronics. The head senses from its top face, sits flush inside a metal mount thanks to its shielded design, and includes a small switch to choose normally open or normally closed output. It carries UL and CSA certifications and is sealed to NEMA 4X and IP67 standards, so it stands up to water, dust, and harsh conditions.

Common Applications

• Replacing a worn or failed head on an existing E51 sensor
• Detecting metal parts on factory and packaging equipment
• Modernizing older mechanical limit switch setups
• Monitoring position on conveyors and material handling systems
• Wet or washdown areas that need a well-sealed sensor

Key Features

• Non-contact detection: Senses metal objects up to 0.51 in away.
• Head-only design: Pairs with any E51 Series body, so a failed head doesn't mean replacing the whole sensor.
• Shielded face: Can be mounted flush in metal surroundings without giving false signals.
• Top sensing: Detection face is located on the top of the unit.
• Selectable output: A built-in switch lets you pick normally open or normally closed operation.
• Rugged sealing: NEMA 4X and IP67 ratings protect against water and dust.

FAQ

What exactly does the E51DT1 do?
It detects metal objects within about half an inch of its top face and signals your control system without any contact.

Do I need anything else to use it?
Yes, you need an E51 Series sensor body. The body provides the power connection and output; the head does the sensing.

How do I know if this fits my sensor?
Check the body of your existing sensor for an Eaton or Cutler Hammer E51 Series catalog number. Any E51 body accepts this head.

What is a shielded proximity sensor?
Shielded means the sensing field stays at the front face, so the head can sit flush in a metal fixture without reacting to it.

Is this part waterproof?
It is sealed to IP67 and NEMA 4X, covering hose-down cleaning, dust, and wet conditions.
