Sensors for Clear Object Detection

2. Q26 Series Sensor Features
Reliable detection of clear, translucent, or opaque objects – including mirror like surfaces
LO / DO Switch
14 mm
270° potentiometer
43 mm
25 mm

3. 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.

5. 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

6. Coaxial Design—Benefit #2
Coaxial sensing beam can shoot through a small aperture; not effected by triangulation effect.

7. Coaxial Design—Benefit #3
50 µs repeatability
250 µs response time
Precise leading edge detection for positioning, the coaxial design results in higher positional accuracy and is not sensitive to sensor rotation
