Wenglor HO08PA3 Reflex Sensor with Background Suppression

The Wenglor HO08PA3 Reflex Sensor with Background Suppression is a compact and highly reliable optical sensor designed for precision object detection in space-constrained industrial applications. Utilizing advanced red light technology, this sensor provides a stable detection range of 80 mm, ensuring accurate switching even when dealing with varied object colors and textures.

Description

The Wenglor HO08PA3 Reflex Sensor with Background Suppression operates on the principle of angle measurement, a technical approach that offers significantly higher accuracy than standard intensity-based sensors. By detecting the angle of reflected light, the sensor maintains a consistent switching point regardless of whether the target is dark, light, or glossy. This makes it an invaluable tool for sorting and positioning tasks where color variations usually cause detection errors.

The sensor’s performance is further enhanced by its impressive switching frequency of 500 Hz and a rapid response time of 1 ms, allowing it to keep pace with modern, fast-moving production lines. Despite its small form factor, it is built for durability with a fully encapsulated housing and a PMMA optic cover. It features comprehensive electrical protection, including short circuit and reverse polarity protection, ensuring long-term operational stability in demanding manufacturing environments.
