The WTA 24 uses an infrared light source and patented system of parabolic mirrors to produce highly accurate, repeatable analog readings
The WTA 24 uses an infrared light source and patented system of parabolic mirrors to produce highly accurate, repeatable analog readings regardless of a targetÃs color or reflectivity. It can even detect objects with as little as 6% reflectivity (tire treads, for instance). With a 5 ms response time, it can easily be integrated into transfer and processing lines. This sensor has a 4 to 20 mA analog output. Operating from 12 to 30 V DC, the WTA 24 offers both short and long sensing distances in three different versions ranging from 10 inches (250 mm) to 10 feet (3 m). The WTA 24 is a cost-effective replacement for mechanical and ultrasonic sensors with superior online monitoring and positioning performance.
