SENPUM – Colour Sensors PC-W Series

Amplifier Built-in Type

The SENPUM PC‑W Series is a line of digital display colour sensors with built‑in amplifiers designed for high‑performance visible‑light colour and object detection using laser light sources. These sensors offer advanced colour contrast sensing and stable detection even over long distances, making them ideal for applications such as part presence detection, colour differentiation, registration mark sensing, and quality inspection in automated production lines. Models within the PC‑W Series include standard, small beam spot, and line spot configurations to support different target sizes and sensing scenarios.

The series features high‑resolution digital displays, multiple timer functions (such as OFF delay, ON delay, disconnect delay, and single trigger), and mutual interference prevention that allows up to 4 units to operate without crosstalk when using the anti‑tamper function. With robust protection circuitry, IP67 environmental resistance, and selectable response modes like MEGA, FINE, and HSPD, the PC‑W Series delivers reliable performance in real‑world industrial environments.
