SICK AG OD50-10P840 Optical Displacement Sensor

Sick OD50-10P840 is a compact optical displacement sensor from SICK AG that measures distance to a target without contact, using a visible red laser. The OD50 family offers a nominal measuring range of 50 mm with a ±10 mm tolerance (40–60 mm) and is designed for non-contact distance determination in automation environments. The OD50-10P840 variant provides a PNP output and a 4-20 mA analog current output through an 8-pin M12 connector, enabling both digital switching and continuous distance monitoring in a single device. It supports teach-in operation for quick reference or zero setting and uses a 650 nm laser diode with a maximum output of 2 mW (laser safety Class 2 per IEC 60825). This sensor is intended for integration into automated systems such as end-of-line inspection, position verification, and alignment tasks on conveyors, fixtures, or robotic workstations where precise, contact-free distance measurement is essential. The model is referenced as OD50-10P840 (part number 6020641) and is documented in SICK OD displacement sensor literature alongside related variants like OD50-10N840 and OD50-10P142, indicating availability in PNP/NPN configurations and multiple output options.
