18 mm Photoelectric Sensor for Industrial Sensing

The Banner QS18APWLPQ2 is a retroreflective photoelectric sensor designed for industrial automation and electrical maintenance tasks. It detects objects at distances up to 3.5 m using a visible red LED beam at 630 nm. The rectangular housing with an 18 mm barrel mount fits standard M18 mounting holes. This new sensor suits technicians who need reliable presence detection in conveyors, packaging lines or material-handling equipment.

20-140 V ac/dc Supply Voltage Range

The sensor operates directly from 20 to 140 V ac or dc without an external power supply, simplifying wiring in mixed-voltage panels. Its P-MOSFET sourcing output switches the load to the positive rail, and the light-operate logic energises the output when the beam is received. Response time is 8.3 ms with 1500 µs repeatability, while a 100 ms dc or 300 ms ac power-up delay prevents false triggers at start-up.

Pigtail Micro Quick-Disconnect for Fast Wiring

A 150 mm pigtail with a 4-pin 1/2 in. micro quick-disconnect connector allows tool-free installation and replacement. The ABS housing carries NEMA 6 and IP67 ratings, tolerating -25 °C to 70 °C and 95 % humidity at 55 °C. Potentiometer adjustment sets the sensing threshold. Installers must provide a suitable retroreflector and ensure the beam path stays clear; the sensor has no remote-teach function and is not rated for intrinsic safety or water detection.

Questions about this item

What does the 3.5 m sensing range mean when the sensor is installed on a machine?

The sensor detects a reflector up to 3.5 metres away using a visible red LED beam at 630 nm wavelength.

How does the 20-140 V ac/dc supply voltage affect wiring and what does the P-MOSFET output cap in practice?

The sensor accepts AC or DC between 20 and 140 volts and provides a sourcing discrete output with an 8.3 ms response time.

What mounting hardware and clearance does the 18 mm barrel with M18 thread need to fit?

The rectangular ABS housing uses an M18 barrel thread and includes a 150 mm pigtail with a 4-pin micro quick-disconnect connector.
