Wenglor HB03PBT7 Reflex Sensor with Background Suppression

Description

The Wenglor HB03PBT7 Reflex Sensor with Background Suppression operates on the principle of angle measurement. This technical approach allows the sensor to detect objects based on their position rather than just the intensity of reflected light. As a result, the sensor provides consistent switching performance even when detecting objects with varying colors or surface textures against a complex background.

Despite its incredibly small size and weight of only 2 grams, this sensor is built for industrial durability. It features a fully encapsulated housing with an IP67 protection rating, making it resistant to dust and water ingress. The sensor’s high switching frequency of 500 Hz and rapid response time of 1 ms ensure it can handle fast-paced production cycles with ease. It also includes comprehensive electrical safety features, such as short circuit and reverse polarity protection, to guarantee a long service life of up to 100,000 hours.
