The Leuze HT25C/4P-M12 is a high-performance photoelectric sensor designed for industrial automation applications requiring precise object detection. Leveraging diffuse reflection technology with background suppression, it accurately identifies metallic and non-metallic targets while ignoring background interference, ensuring reliable operation in complex environments. With a maximum sensing range of 1.2 meters (white 90% reflectivity) and adjustable sensitivity via a multiturn potentiometer, it adapts to various object colors and surfaces, including dark or transparent materials. The sensor features a red LED light source (640 nm wavelength) and a compact cubic housing (15 x 42.7 x 30 mm), making it suitable for space-constrained installations. Its IP67/IP69K protection rating withstands dust, water jets, and high-pressure cleaning, ensuring durability in harsh industrial settings .
Equipped with two independent PNP transistor outputs, the HT25C/4P-M12 offers versatile switching options: one for "light-on" (object detected) and another for "dark-on" (no object detected). This dual configuration enables simultaneous monitoring of two distinct processes or redundancy in critical applications. The sensor operates on a 10–30 V DC power supply with short-circuit and reverse-polarity protection, ensuring compatibility with standard industrial systems. It delivers a fast response time of 0.5 ms and a switching frequency of 1,000 Hz, ideal for high-speed conveyor belts or packaging lines where rapid detection is essential. The M12 x 1 4-pin PUR connector guarantees secure and vibration-resistant connections, while the -40°C to +60°C operating temperature range ensures stability in extreme climates .
The HT25C/4P-M12 excels in intralogistics, packaging, and factory automation by detecting objects on conveyor belts, sorting systems, or assembly lines. Its background suppression technology eliminates false triggers from reflective surfaces or adjacent objects, making it suitable for detecting transparent films, glossy plastics, or small parts. The sensor’s adjustable range (50–1,200 mm) and small light spot design (15 mm x 40 mm at 300 mm) enhance precision in tight spaces. Additionally, its c UL us certification and compliance with IEC 60947-5-2 standards ensure global compatibility. Whether used in food processing plants (due to Ecolab-compliant materials) or automotive manufacturing, this sensor optimizes productivity by minimizing downtime and improving process reliability .
