Infrared emitter for opposed-mode sensing

The Banner QS186EQ8 is an infrared emitter designed for opposed-mode photoelectric sensing. It projects a sensing beam up to 20 m using a 10-30 V dc supply. The rectangular ABS housing features an M18 mounting thread and an integral M12 quick-disconnect connector. It is built for industrial detection tasks where a separate receiver completes the sensing pair.

Suited for long-range through-beam applications

This emitter suits installations that require a 20 m range in opposed-mode configurations. It is not for applications needing a built-in receiver or switching output, as the unit provides no outputs. Buyers who need diffuse, retroreflective or background-suppression sensing should look at other sensor types. The fixed 100 ms power-up delay and lack of adjustments also limit use in high-speed or finely tuned setups.

20 m range at 10-30 V dc

The 20 m maximum sensing distance at 10-30 V dc is the key specification that determines whether this emitter matches the application. The IP67 and NEMA 6 ratings confirm suitability for wet or dusty environments. Operating temperature spans -20 °C to 70 °C with 95 % relative humidity at 50 °C. The acrylic lens and infrared LED complete the optical path for the paired receiver.

Questions about this item

What is the barrel diameter and thread size for mounting the QS186EQ8 emitter?

The sensor has an 18 mm barrel diameter with an M18 mounting thread. It fits a standard 18 mm clearance hole and is secured with the supplied lock nuts.

How do I wire the M12 quick-disconnect connector on this emitter?

The integral M12 Euro-style connector has 4 pins. Connect pins 1 and 3 to a 10-30 V dc supply (brown positive, blue negative). Pins 2 and 4 are unused on this emitter-only model.

When should I replace the acrylic lens or the infrared LED emitter?

Replace the acrylic lens if it becomes scratched, cracked or clouded, as this reduces the 20 m range. The infrared LED is rated for long life; swap the unit if the indicator LEDs show no emission despite correct voltage.
