SENPUM – PH2-T Transparent Detection

Transparent Detection Type

Brand : SENPUM

The SENPUM PH2‑T Series is a line of transparent object detection photoelectric sensors designed to reliably detect both transparent and opaque objects in industrial automation applications. These sensors use an infrared reflective detection method optimized for transparent materials, enabling stable and accurate sensing even for objects that are difficult to detect with standard reflective sensors. The PH2‑T Series supports adjustable sensitivity and selectable LIGHT‑ON/DARK‑ON output modes, making them versatile for conveyor systems, bottle inspection, and packaging applications where transparent components must be reliably identified.

PH2‑T Series sensors feature robust signal processing and LED light sources that improve interference resistance and alignment ease. With compact housings and straightforward button or switch‑based configuration, these sensors are easy to install and adjust in production lines. Protection circuits and IP66 environmental ratings help ensure dependable operation in industrial conditions.
