SICK Sensor Intelligence UF3-70B410 Ultrasonic Fork Sensor

The SICK UF3-70B410 Ultrasonic Fork Sensor is a compact, slot-style device designed to detect thin labels and small objects as they pass through a 3 mm-wide fork opening. It operates from 10 to 30 V DC with reverse-polarity protection and short-circuit protection in the supply circuit, and its housing measures 16 mm (W) × 48 mm (H) × 92 mm (D) with a fork depth of 69 mm. The sensor offers an ultrasonic sensing range of 0 to 3 mm and a minimum detectable object of about 2 mm, with label-detection functionality and adjustable sensitivity via a plus/minus button—performance depends on label thickness. Catalogued as UF3-70B410 (part number 6034888), this is a pre-owned unit suited for inline packaging lines, label verification on conveyors, or printers where a narrow fork sensor enables reliable detection without contact. Its design fits compact control schemes powered by 10–30 V DC, making it a practical choice for space-constrained applications requiring precise, non-contact detection of small features.
