    • DENKI SEIGYO PU-MQ-B30N & PU-MQ-B30P PHOTO SENSOR

    Product Overview

    The PU-MQ-B30N/P is a high-performance Diffuse Background Separation (BGS) photoelectric sensor designed to reliably detect black, translucent, highly reflective metals, and mixed-color objects. With a strong BGS algorithm, it achieves precise discrimination with minimum black/white difference within 2 mm, making it ideal for demanding industrial automation environments.

    Built using imported German ultrasonic welding technology, the housing is dustproof and waterproof, featuring reinforced cabling with copper sleeve protection and robust workmanship for long service life. Integrated polarity and surge protection allows resistance up to 48 V shock without affecting normal operation.
