SICK MHT15-N4347S04 Tray Proximity Sensor

The SICK MHT15-N4347S04 Tray Proximity Sensor is a compact, M18-threaded photoelectric proximity device from SICK’s MH15 family designed to detect tray presence on conveyors and in packaging lines. It measures 18 x 18 x 36.8 mm with a cylindrical housing and M18 x 1 thread, using infrared light (950 nm) and an LED light source along an axial optical axis for reliable detection. The sensing range is adjustable from 10 mm to 350 mm via a 270° potentiometer, allowing precise tuning for different tray sizes and gaps. The light spot size is about Ø50 mm, with dispersion around 4.5°, making it suitable for tight sensing zones, and a health output indicates targets with high reflectivity (approximately 90% remission per DIN 5033). Designed for longevity, it offers an average service life up to 100,000 hours at +25 °C, supporting heavy-duty industrial use. Typical applications include tray presence/absence detection in packaging, inline sorting, and other automated processes where a small, rugged photoelectric sensor is advantageous. The part number is 1027544, ensuring exact model identity within the MH15 series for replacement or specification-integration in control systems.
