SICK WT45-R260 Photoelectric Sensor

The SICK WT45-R260 is a compact, background-suppressed photoelectric proximity sensor with a built‑in relay output designed for reliable object detection on industrial lines. It senses targets from 200 mm up to 2,000 mm away using infrared light emitted by a LED, with a light spot about 35 mm at the 2 m distance. The rectangular housing measures 60 mm wide by 105 mm high by 105 mm deep and is adjusted via a potentiometer for sensitivity. It provides a cable gland for conductors from 0.14 mm2 to 2.5 mm2 and is available in a 2 m cable-length variant, powered from 20 to 250 V DC with a relay output. The performance specification notes 90% remission (DIN 5033) for object reflectivity, ensuring reliable detection of bright or reflective surfaces. Life expectancy is rated around 100,000 hours at 25 °C, suitable for demanding industrial environments. The WT45-R260 is well suited for production-line sensing tasks where background suppression reduces false triggers and improves consistent presence detection.
