Eaton Comet 18mm Tubular Photoelectric Sensor, Retroreflective

The Eaton Comet 18mm Tubular Photoelectric Sensor is a forward-viewing, non-polarized retroreflective sensor built for reliable object detection in industrial control applications. It delivers a sensing distance of up to 25 Ft (based on a 3-inch diameter retroreflector, sold separately) and provides an NPN/PNP open collector output rated 100 mA PNP / 250 mA NPN max DC at a 10-30 Vdc supply range. Backed by UL Recognized and CE Marked compliance, this sensor is engineered for dependable performance in demanding automation environments.

Key Features

  • Sensing Distance: Up to 25 Ft in non-polarized retroreflective mode, based on a 3-inch diameter retroreflector (retroreflector not included – order sensor and retroreflector separately for a complete system).
  • Compact 18mm Tubular Housing: Forward-viewing design supports flexible mounting in tight machine and conveyor spaces.
  • Dual NPN/PNP Open Collector Output: Rated 100 mA PNP / 250 mA NPN max DC for broad compatibility with PLC and control system inputs.
  • Wide Operating Voltage: 10-30 Vdc supply range suited to standard industrial control power.
  • Cable & Connector: 6.6 Ft (2m) Polyvinyl Chloride (PVC) cable with a 4-pin connection for straightforward field wiring.
  • Rated Operating Temperature: -40°F to 158°F, supporting use across demanding industrial environments.
  • Maximum AC Current: 300 mA.
  • 3-Year Warranty backing long-term operational reliability.

Eaton 14100A6517 – Frequently Asked Questions

1) Does the Eaton Comet 18mm retroreflective sensor come with the reflector, or do I order that separately?
The reflector is a separate order. The Comet 18mm retroreflective sensor's 25 ft sensing distance is based on a 3-inch diameter retroreflector, and that reflector is not included. Budget for both the sensor and a reflector (plus the mounting bracket for it) to get a working system.
2) What is the difference between the two connection options on the Eaton Comet 18mm sensor?
Two build-outs are offered. One is the DC version, NPN and PNP open collector output with a 6.6 ft (2 m) attached cable, MPN 14100A6517. The other is an AC version with L1 switched contact configuration and a dual key micro quick-disconnect, MPN 14101AQD03. Pick the cable version for hardwiring into a panel and the dual key micro for a plug-and-play machine harness.
3) Can I use this sensor in an unheated warehouse or a cold storage dock?
Rated operating temperature runs from -40 degrees F up to 158 degrees F, so unheated docks, freezer vestibules and hot packaging lines are all inside the band. One caution on cold work: the lead is PVC cable, which stiffens at the low end of that range, so support it and avoid flexing it in continuous motion at deep-freeze temperatures.
4) Should I use a retroreflective sensor or a through-beam setup for conveyor object detection?
Retroreflective, like this Comet 18mm unit, puts emitter and receiver in one housing and bounces the beam off a reflector on the far side, so you only run power and signal to one side of the conveyor. That is the cheaper install. Through-beam needs wiring at both ends but tolerates dirt and longer spans better. This sensor is a non-polarized retroreflective type, which is worth knowing: non-polarized means a shiny target can bounce the beam back and read as no-object, so avoid it where you are detecting bright metal or clear film.
5) How many conductors do I need to land for this Eaton sensor?
It is a 4-pin device, so plan on four conductors: supply positive, common, and the output leads for the NPN/PNP open collector. The cable version comes with 6.6 ft (2 m) of PVC lead, so if the panel is farther than that you will need a junction or an extension cordset.
6) Is the Eaton Comet photoelectric sensor UL listed or CE marked?
The Comet 18mm sensor is UL Recognized and CE Marked. UL Recognized means it is approved as a component for use inside listed equipment rather than as a standalone listed product, which is the normal status for a machine-mounted sensor going into a control panel.
7) Can this sensor switch a solenoid or relay coil directly, or does it need an interposing relay?
Check the load current first. The DC output handles 100 mA on PNP and 250 mA on NPN, and maximum AC current is 300 mA. That is fine for PLC inputs and small pilot relays, but anything drawing more than those figures, a contactor coil or a valve bank, needs an interposing relay between the sensor and the load.
8) How far can the Eaton Comet 18mm sensor actually see?
Up to 25 ft in non-polarized retroreflective mode, and that figure assumes a 3-inch diameter reflector. Use a smaller reflector and the usable range drops, so size the reflector to the span you need rather than assuming 25 ft on any target.
