DL50-P1123 Laser Distance Sensor 200-50000mm Analog PNP | SICK

The Original New SICK DL50-P1123 (1047361) is a mid-range laser distance sensor from the Dx50 series, designed for precise, non-contact distance measurement in automated industrial applications. Using time-of-flight measurement with a visible red laser (Class 1, 658 nm), it achieves a measuring range of 200 mm to 50,000 mm on “Diamond Grade” reflective tape, with 1 mm resolution and ± 7 mm accuracy. The sensor provides one PNP digital output and one analog output (4–20 mA or 0–10 V), and supports teach-in, parameterisation, and invertible output functions. Housed in a rugged enclosure rated IP65/IP67, it is suitable for logistics, material handling, and positioning tasks where optical challenges such as ambient light are present. The sensor includes an LC display for on-site configuration and connects via an M12 5-pin connector.

Core Engineering Highlights:
