Cylindrical photoelectric sensor receiver, 18 mm diameter, right-angle 1/2 in connector

IFM Efector Inc

IFM Efector Inc OG0039 Through-Beam Photoelectric Sensor Receiver 1/2 in Connector Right

SKU CH-S19D-S73TY

A through-beam photoelectric receiver with an 18 mm cylindrical body, 15 m sensing range, 20–250 V AC/DC supply, and a 3-pin 1/2 in male connector

  • TypeIndustrial Electrical Controls & Automation
  • Through-beam detection reaches 15 m range
  • Dark-on output signals when beam is blocked
  • 18 mm cylindrical housing fits tight spaces
  • 20 to 250 V AC/DC supply covers many plants
  • 3-pin 1/2 in connector enables quick wiring

Industrial Through-Beam Receiver

The IFM OG0039 is a cylindrical photoelectric sensor receiver designed for 18 mm mounting holes. It operates on 20 to 250V AC/DC supply and connects via a 3-pin 1/2 inch male connector. The unit functions in dark-on mode for presence detection in automated production lines and packaging equipment.

Replaces Wired Limit Switches

This receiver replaces mechanical limit switches that wear out from physical contact or contaminant ingress. The jump is worth it when the application demands non-contact sensing across a 15 m gap with consistent repeatability. It suits installations where vibration or dust cause false triggers on traditional contacts.

Stable Output Under Continuous Operation

The AC circuit type maintains a steady signal during prolonged exposure to ambient light changes or target flutter. The 18 mm cylindrical housing resists oil and coolant splash common in machining cells. Performance remains consistent across the full voltage range without thermal drift during extended shifts.

Questions about this item

What diameter cut-out does the 18 mm cylindrical receiver need?

The receiver body is 18 mm in diameter, so a matching 18 mm hole or bracket is required for mounting.

How do I wire the 3-pin 1/2 in male connector and avoid the common polarity mistake?

Connect the three pins to a 20 to 250V AC/DC supply; the dark-on output switches when the beam is broken, so verify load wiring before powering up.

When should I plan to clean or replace the lens on this through-beam receiver?

Inspect the lens whenever sensing range drops below the rated 15 m; wipe with a lint-free cloth and replace the unit if the housing or connector shows damage.
