Sunx SX-23 Photoelectric Sensor

The Sunx SX-23 Photoelectric Sensor is a compact beam-type sensor designed for reliable non-contact detection in tight industrial spaces. As part of Panasonic SunX’s ultra-compact photoelectric family, the SX-23 is well suited for conveyors, packaging lines, pick-and-place cells, and end‑of‑line presence checks where a small footprint matters. The SX-23 shares the through-beam style common to SunX’s EX-23 lineage, offering robust sensing in challenging environments, with typical system specs including a 12–24 V DC supply, NPN output, an IP67 enclosure, a sensing range around 2 meters, and a 2 m cable. Users can usually choose light-on or dark-on operation and adjust sensitivity via a compact one-turn potentiometer, enabling stable performance across varying object colors and finishes. The sensor’s rugged enclosure and straightforward mounting support panel, rail, or machine-frame installations, and its slim profile is advantageous for tight spaces along conveyors or inside recessed areas. Common applications span part detection on food, packaging, pharmaceutical, and electronics assembly lines, carton empty-detection, and automation safety interlock contexts where a durable, low-profile sensor is required.
