SICK ET3-P5728 Photo Sensor PNP Lo M12 Health 10-30VDC

The SICK ET3-P5728 Health variant is a compact ELF3 photoelectric sensor with a PNP switching output and a 10–30 V DC supply, designed for reliable object detection across a 5 mm to 155 mm range using infrared light at 880 nm. It features an M18 housing with an M12 4‑pin connector, measuring 23.8 × 43.4 × 33.6 mm and offering IP67 protection for demanding industrial environments; its focused optics and a light spot of roughly 31 mm × 31 mm at 150 mm support stable sensing of small or reflective targets. The unit typically draws about 20 mA, operates from −25 °C to +50 °C, and is built for long service life with an estimated 100,000 h at 25 °C. This configuration makes it suitable for compact installations on conveyors or packaging lines where a rugged, low‑voltage sensor with a PNP output is required and health/status monitoring is desired.
