IFM OG0030 Through-Beam Transmitter

The IFM OG0030 is a cylindrical photoelectric sensor transmitter designed for through-beam detection tasks. It operates on a wide 20 to 250V AC/DC supply, making it suitable for diverse industrial voltage environments. The 18 mm threaded housing allows standard mounting in machinery frames or brackets. This unit functions as the light source in a paired sensor system.

3-Pin 1/2 Inch Connector Interface

The transmitter terminates in a 3-pin 1/2 inch male connector for quick electrical hookup. This connection style simplifies wiring in control cabinets or junction boxes without requiring specialised tools. The AC circuit type matches the broad voltage input range for direct line integration. No separate power conditioning accessories are included in the package.

Simple 18 mm Mounting and Alignment

Installation involves securing the 18 mm barrel through a drilled hole or clamp and tightening the lock nuts. The main challenge is precise optical alignment with the separate receiver unit across the 50 ft maximum sensing distance. Vibration or bracket shift can break the beam and cause false triggers. Ensure the connector orientation allows cable routing without strain.

Questions about this item

Does the 18 mm cylindrical transmitter require periodic emitter replacement?

The transmitter uses a through-beam light source with no user-replaceable emitter module, so no scheduled replacement is needed.

What limits continuous operation of the 20 to 250V AC/DC transmitter?

The AC circuit type and 3-pin 1/2 in male connector define the electrical limits; sustained use stays within the rated voltage range.

How much heat or noise does the 50 ft range transmitter produce when running all day?

As a passive light-on transmitter with no moving parts or active cooling, it generates negligible heat and no audible noise.
