Eaton Comet Series Through-Beam Photoelectric Sensor, Forward Viewing

The Eaton Comet Series Through-Beam Photoelectric Sensor is a tubular photoelectric sensor engineered for forward-viewing, through-beam object detection in demanding industrial environments. Built with a durable polyurethane foam (RIM) enclosure, this sensor operates on a 10-30 Vdc input and features an Output ON LED indicator for at-a-glance status monitoring. Rated NEMA 1, NEMA 3, NEMA 4, NEMA 4X, NEMA 6, NEMA 12, NEMA 13, and IP69K, and carrying a UL Recognized listing, it is designed for reliable performance across washdown, wet, and dusty applications.

Key Features

  • Sensor Type: Through-beam sensing configuration with forward viewing orientation for accurate object detection.
  • Compact Construction: Polyurethane foam (RIM) enclosure measuring .47 in wide, 2.55 in in length/depth, and .71 in in height for a low-profile tubular form factor.
  • Input Voltage: 10-30 Vdc input voltage supports flexible integration with standard DC control systems.
  • Contact Configuration: NPN and PNP open collector outputs with a maximum DC current of 100 mA PNP / 250 mA NPN.
  • Contact Rating: 100 mA PNP, 250 mA NPN at 10-30 Vdc for dependable switching performance.
  • Short-Circuit Protection: Auto reset short circuit protection helps safeguard the sensor circuit during fault conditions.
  • Operating Temperature Range: Rated from -4 °F to 158 °F for use across a wide range of ambient conditions.
  • Cable: Polyvinyl Chloride (PVC) cable with a 79.2 ft cord length for flexible routing to controllers, plus an Output ON LED indicator for visual status feedback.

Eaton 12100A6517 – Frequently Asked Questions

1) Can the Eaton Comet through-beam sensor be used in a washdown area that gets hosed down daily?
Yes. The Comet Series through-beam photoelectric sensor is rated IP69K and carries NEMA 1, 3, 4, 4X, 6, 12 and 13 ratings, which covers high-pressure, high-temperature washdown as well as wet and dusty duty. The enclosure is polyurethane foam (RIM) and the cable is PVC. Ambient range is -4 F to 158 F, so it will also handle a chilled packaging room or a warm process area.
2) Do I need to buy a separate emitter and receiver for a through-beam setup?
Through-beam sensing uses an emitter on one side of the gap and a receiver on the other, with the target breaking the beam between them. The Comet Series here is configured as through-beam, so plan the opening for a unit on each side of the conveyor or chute and route power to both locations. If mounting on only one side is possible, a retroreflective or diffuse sensor is the configuration you want instead.
3) How long is the cable on the Eaton Comet photoelectric sensor, and do I need a connector?
It ships with a PVC cable 79.2 ft long, so in most machine or conveyor installs you can pull the lead all the way back to the control panel without a field connector or a junction box. No quick-disconnect is part of the sensor, the cable comes attached.
4) How tight a space will this tubular photoelectric sensor fit into?
The body is small: .47 in wide and .71 in high. That lets it tuck into guarding, under a conveyor rail, or between machine frames where a block-style sensor will not go. Confirm your bracket suits a tubular barrel rather than a flat-mount housing.
5) What happens if the sensor output gets shorted in the field?
The Comet sensor has auto reset short circuit protection on the output, so a shorted load or a pinched lead shuts the output down and it recovers on its own once the fault is cleared. No fuse to replace in the panel. The Output ON LED on the sensor gives you a quick visual check of output state while you troubleshoot.
6) Is the Eaton Comet sensor UL listed for my facility spec?
It carries a UL Recognized listing, which means it is a component certified for use inside a larger piece of equipment rather than a standalone UL Listed end product. For a panel or machine build that is normally what a specifier wants. It is also IP69K rated and covers NEMA 1 through 13 enclosure types as listed.
