  • Color mark recognition sensor | 10mm | 97x45x26mm | 12-24VDC | NO+NC | PNP | 2 m cable | PBT | red/green light beams | IP65

    Code: SPM-TPR-RG

    The color mark sensor is a precise sensor designed for detecting color marks and contrasts in various automation, packaging, and production systems. It uses visible red and green light beams, allowing it to accurately distinguish different colors or markings even on glossy, reflective, or semi-transparent surfaces.

    Made from durable PBT plastic with an IP65 protection rating and integrated protection against short circuits, overvoltage, and polarity errors, the sensor ensures reliable operation in industrial environments, technical projects, and home automation applications.
