43 mm

270° potentiometer

14 mm

25 mm

Product Features & Development Strategy

■ Reliable detection of clear films, bottles, vials, glass plate, and other transparent objects.

■ Uses a coaxial optical design where the emitted and reflected light travels on the same path.

– Coaxial optics, also called the “autocollimation principle”

■ Crossed polarizer in the optical path prevents missed detection of glossy or metallic targets.

Q26 for Clear Object Detection

Coaxial Design—Benefit #1

■ Coaxial design provides three additional benefits when using the sensor in some applications…

– A coaxial optical design allows for very short sensor to reflector separations distances in machines with limited space

Coaxial Design—Benefit #2

Coaxial sensing beam can shoot through a small aperture; not effected by triangulation effect.

Coaxial Design—Benefit #3

Precise leading edge detection for positioning,the coaxial design results in higher positional accuracy and is not sensitive to sensor rotation

50 µs repeatability

250 µs response time

Q26 Series Sensor

* Range with BRT-60X40C. Range dependent on reflector in use. Please consult the datasheet for details.

Q26 Applications

■ Filling and bottling machines

■ Flat glass or LCD manufacturing

■ Pharmaceutical vials or bag filling machines

■ Any high-speed application where positioningis critical
