Eaton 50 Series Photoelectric Sensor, Right Angle Diffuse Reflective Sensor

The Eaton 50 Series Photoelectric Sensor is a right-angle, diffuse reflective photoelectric switch built for reliable object detection in industrial control panels and machine automation systems. It delivers a sensing distance of up to 72 In. based on a 90% reflectance card, with NPN and PNP open collector outputs rated 250 mA at 30 Vdc and a 10-30 Vdc input range with reverse polarity protection. The rugged housing carries NEMA 1, NEMA 3, NEMA 4, NEMA 12, and NEMA 13 environmental ratings, making it suitable for demanding plant-floor environments.

Key Features

  • Sensing Distance: Up to 72 In. based on a 90% reflectance card for reliable diffuse reflective detection.
  • Diffuse Reflective Operation: Detects targets directly without a separate reflector, simplifying installation.
  • Right Angle Design: Compact right-angle body eases mounting in tight panel and machine spaces.
  • Dual Output Configuration: NPN and PNP open collector outputs rated 250 mA at 30 Vdc for flexible control wiring.

Eaton 1351B-6517 – Frequently Asked Questions

1) Does the Eaton 50 Series diffuse reflective sensor need a separate reflector or receiver?
No. The 50 Series right-angle sensor works in diffuse reflective mode, so the emitter and receiver are in one body and the target itself bounces the beam back. You mount one device on one side of the conveyor or machine frame and wire it, with nothing to align on the opposite side. Sensing range runs up to 72 inches against a 90% reflectance card, so dark or matte targets will detect at shorter distances than that figure.
2) Can I wire the Eaton 50 Series photoelectric sensor into a PLC input that needs a sourcing (PNP) signal?
Yes. The sensor carries both NPN and PNP open collector outputs, so it drops onto either a sinking or a sourcing PLC input card without an interposing relay. Output is rated 250 mA at 30 Vdc, which is plenty for a digital input or a small interposing relay coil but not for driving a contactor directly.
3) Can this sensor be mounted on a washdown or outdoor conveyor line?
The housing carries NEMA 1, 3, 4, 12 and 13 ratings, which covers hose-directed water and dust as well as oil and coolant splash typical of machine tool areas, plus outdoor weather exposure under the NEMA 3 rating. Operating temperature is -40 F to 158 F, so unheated warehouses and cold storage docks are within range.
4) What is the difference between the Eaton 1351B-6517 and 1352B-6517 sensors?
Both are the same right-angle diffuse reflective 50 Series body; the ordering difference is the input voltage option, with 1351B-6517 listed at 30 volts and 1352B-6517 at 10 volts. The sensor family itself operates across a 10-30 Vdc range, so pick the part number that matches how your panel supply is specified.
5) How much room do I need to fit this sensor in a tight machine guard area?
The right-angle body measures 3.19 in by 1.83 in by 1.64 in. The right-angle configuration puts the lens on the face perpendicular to the cable exit, which is what lets it tuck against a frame rail or bracket where a barrel-style sensor would need clearance straight back for the cable.
6) Should I use a diffuse reflective sensor or a through-beam type for conveyor detection?
Diffuse, like this Eaton 50 Series unit, is the simpler install: one device, one wiring run, no opposing bracket to align, and up to 72 inches of range on a 90% reflectance card. It is the right pick when you cannot mount anything across the conveyor or the target is reasonably light-colored and consistent. Through-beam or retroreflective types are the better answer when the target is dark, shiny, or irregular, or when you need long range across a wide opening, because they do not depend on how much light the object itself returns.
7) How do I tell if the sensor is actually seeing the target during setup?
There is a red LED output status indicator on the body. During commissioning you walk the target through the beam and watch the LED change state, which lets one technician set the sensing position without a meter or a second person at the panel.
