SICK WE260-F270 Weighing Sensor

WS/WE260-F270 is a compact through-beam photoelectric sensor from SICK (part number 6020973) in the W260 family, designed for reliable non-contact detection along conveyors and packaging lines. The 25 mm x 78 mm x 63 mm housing fits tight mounting spaces, and the unit provides a sensing range of 0 to 30 m with a maximum range of 0 to 35 m; the optical focus is about 1.4°, and the light is a visible red LED with a light spot of about Ø700 mm at 30 m. It is powered from a 10 V to 30 V DC supply with ripple under 5 Vpp, drawing roughly 20 mA on the emitter side and about 35 mA on the receiver side. An adjustable potentiometer (270°) lets you dial in the sensing distance for your application, and the average service life is rated at 100,000 hours at 25 °C. The device offers a switching output configured as a change-over (relay) contact, suitable for use in standard automation circuits with light/dark ratio of 1:1. Common applications include presence and part-detection checks on conveyors, stack-and-pack lines, and other automated material-handling setups where non-contact sensing and long-range reliability are required. This WS/WE260-F270 model pairs SICK’s precision optics with robust electronics in a compact form factor, making it a straightforward fit for installations requiring long-range, single-beam sensing without complex wiring.
