SICK DL50-P1123 Industrial Photoelectric Sensor

DL50-P1123 is a time‑of‑flight laser distance sensor from SICK that provides non‑contact distance measurements from 0.2 m up to 50 m with 1 mm resolution, enabling precise sensing in industrial environments. It operates on 10–30 V DC and draws roughly 20 mA, delivering a PNP output through a 5‑pin M12 connector for easy integration into control systems. The device is IP65 rated, resisting dust and water spray typical of factory floors, and uses visible red light at 658 nm to perform measurements. The DL50-P1123 lists a repeatability of ≥ 2 mm across its range, with response times in the 15–30 ms band and output times of at least 4 ms depending on configuration. A representative spot size at 10 m is about 15 mm × 15 mm when using a Diamond Grade reflective tape target, illustrating the influence of target reflectivity on measurement. Operating temperature ranges from −30 to +65 °C, making it suitable for demanding environments, and its long‑range capability supports applications such as part distance checks, presence/absence verification, and process monitoring within automation lines.
