Banner Through Beam Photoelectric Sensor, Block Sensor, 50 mm Detection Range

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.
Operating temperature range -20 to +70°C
IEC IP67, NEMA 6 Rated

Miniature Self-Contained Photoelectric Sensors in Universal Housing

Easily its (or retrofits) almost any mounting situation
Exceptional optical performance, comparable to larger MINI-style” or barrel sensors
10 V dc to 30 V dc operation, with complementary (SPDT) NPN or PNP outputs, depending on model
Bright LED operating status indicators are visible from 360°
Rugged sealed housing, protected circuitry
Models available with or without 18 mm threaded “nose”
Less than 1 millisecond output response for excellent sensing repeatability Choose 2 m (6.5 ft) or 9 m (30 ft) cable or 150 mm (6 inch) Pico-style cabled QD
