The SensoPart FR 25-RLO2-PNSL-K4 is a high-performance autocollimation laser photoelectric retro-reflective sensor designed for precision and reliability. With a working distance range of 0 to 4 meters, this sensor utilizes a red laser light source (Class 1) for accurate detection. It features a teach-in adjustment method and an auto-detect switching output that supports both PNP and NPN configurations. Operating at a velocity of 4 kHz, it ensures rapid response times suitable for dynamic applications. The sensor is equipped with a 2-meter, 4-wire cable and an IO-Link interface for seamless integration into various systems. Its robust design includes an IP69 enclosure rating, making it suitable for harsh environments with a temperature range of -20 to +60°C. The compact F25 series dimensions (34 x 20 x 12 mm) allow for easy installation in space-constrained areas.
