Emitter for opposed-mode sensing

The Banner SM31EL is a Mini-Beam series emitter designed for opposed-mode photoelectric sensing. It projects an infrared LED beam up to 30 m and operates on a 10-30 V dc supply. The rectangular housing features an M18 mount and a 2 m attached cable. It is built for industrial environments requiring a dedicated light source paired with a separate receiver.

Suits long-range through-beam applications

This emitter suits installations needing a 30 m sensing range with a compact 18 mm barrel. It is not for applications requiring a built-in receiver or switching output, as the unit provides no output function. Buyers who need a self-contained sensor with detection logic should look at a different device. The lack of quick-disconnect also means the cable is fixed.

30 m maximum sensing distance

The key specification is the 30 m maximum sensing distance, which determines whether the emitter reaches the intended receiver across the gap. This range is achieved with the infrared LED beam in opposed mode. Verify that the matching receiver and installation geometry support this distance before selecting the SM31EL.

Questions about this item

What size mounting hole does the 18 mm barrel on the SM31EL emitter require?

The rectangular housing has an M18 mount, so a standard 18 mm clearance hole fits the barrel.

How do I wire the 2 m cable on this emitter, and which step is often missed?

Connect the two conductors to a 10-30 V dc supply; the step often missed is observing polarity on the unmarked leads.

When should I replace the acrylic lens on this IP67 emitter?

Replace the lens if it becomes scratched, cloudy or cracked, as damage reduces the 30 m infrared beam range.
