The WORLD-BEAM QS18 series of photoelectric sensors offer exceptional optical performance in compact QS18 housing and a unique space saving housing design that directly replaces barrel/rectangular style sensors.
The sensors have a reliable detection when a fixed background is present and the object colour or shape when the shape varies.
The QS18 series of sensors are available in opposed, polarized or non-polarized retro-reflective, convergent, regular or wide-angle diffuse, laser, ultrasonic, plastic or glass fibre optic, fixed-field and adjustable-field sensing modes.

ABS housing with 3mm mounting hardware included
10Vdc to 30 Vdc supply voltage
Single turn sensitivity potentiometer on retro and diffuse models (finger or screwdriver adjustable)
Solid-state complementary (SPDT): NPN or PNP (current sinking or sourcing), depending on model
2 LED indicators on sensor top
Fast response times
2m pre-cabled or 4-pin, 150mm Pico-style pigtail connector.
All models supplied with mounting bracket, polarised retro model supplied with reflector
Operating temperature range -20 to +70°C
IEC IP67, NEMA 6 Rated

Check your automated system's products on the fly with this photoelectric sensor from Banner. As a diffuse model, it combines emitting and receiving functions in one housing for a compact sensing solution. Thanks to its snappy 0.7ms response time, the device quickly spots gaps and misalignment. Installation is a breeze with its simple quick-disconnect socket. The sensor's IP67 rating demonstrates it's fully protected against dust and water sprays typically found in demanding industrial conditions, keeping contamination out of the equation.
