SICK WSU 26-120 5VA 110 120V Optic Photoelectric Sensor

SICK WSU 26-120 is a through-beam optic photoelectric safety sensor (sender) designed for machine guarding, operating from 110–120 V AC with a 5 VA load and intended to be paired with the WEU 26/2 receiver to form a single-beam safety light-beam system. It provides a sensing range from 0.5–30 m with a fast response time up to 22 ms, and its enclosure carries IP65 protection with standard connectors (IP67 when configured with a PG gland), making it suitable for harsh industrial environments. As part of the WSU26 family, it supports integration with common industrial networks and safety controllers, including fieldbus options such as EtherCAT, EtherNet/IP, PROFINET, CANopen/DeviceNet, and Modbus TCP, enabling safe interlock and stop signals within compatible safety circuits. This single-beam device is typically used to detect interruptions in the beam path and trigger protective action in compliant systems per EN 61496-1/2, providing reliable long-range sensing for manufacturing lines.
