B-Line E51CLT66PU E51 Series, Limit Switch Style, Factory Sealed 6P+ Inductive Proximity Sensor

Yes. The E51CLT66PU is a 120Vac input device with a 1.0A solid state output, so it wires straight into a 120V control circuit without a separate DC supply. Output current is capped at 1.0A maximum AC, so size the load (contactor coil, relay, PLC input module) accordingly.

It is rated NEMA 3, 3S, 4, 4X, 6, 6P, 12 and 13, equivalent to IP68, and the unit is factory sealed with an 8 ft integral cable rather than a conduit entry. That combination covers high pressure washdown, corrosive duty (4X) and temporary submersion (6P). Housing is die cast zinc with a plastic sensing head.

The head can be unfastened and rotated to any of four positions, which is how you handle an awkward target approach without remounting the body. It cannot be removed, though, because the head is hard wired to the sensor body.

Inductive sensing means the target has to be metal; plastic, wood or liquid will not trigger it. This one operates un-shielded, so the field extends out the sides of the head as well as the face. Mounting it flush in a steel bracket or close to other metal can cause false operation, so keep clear space around the sensing face.

It is built in the limit switch body style, so it mounts and wires in the same place a 120V mechanical limit switch does, but it senses metal targets by induction instead of by physical contact. There is no lever or plunger to wear out. If your application needs actual mechanical contact, or the target is non-metallic, an inductive sensor is the wrong choice.

Rated -13 to 158 degrees F (-25 to 70 degrees C). That covers unheated warehouses, outdoor conveyor lines and most northern winter installs, along with hot process areas up to 158F. NEMA 3 and 3S in the enclosure rating cover rain, sleet and external icing.

It ships with 8 ft (2.5 m) of SOOW-A cable already sealed into the body. Plan a landing point within that 8 ft run or splice in a rated box, since the cable is integral and there is no connector to extend at the sensor.

No. Protection is listed as none, so the 1.0A solid state output is not internally protected. Fuse the output circuit yourself and keep the load inside the 1.0A limit, or a shorted load will take the sensor with it.

There is an LED for each output that lights when that output is ON, so a tech can jog the machine and watch the light to set the gap and confirm sensing before anything is wired downstream. Contact configuration is L1 switched.

Accuracy is under 0.3%, which is tight enough for position confirmation and part-present checks on a conveyor or press. For precise dimensional measurement you want a measuring device, not a proximity switch.
