Ask for availability. BKS-3/CIU. The Microsonic bks-3/CIU is an ultrasonic web edge sensor designed for precise edge detection of sound-impermeable materials such as foils and paper. Operating within a measuring range of 6 mm (±3 mm), it is ideal for guiding highly transparent materials like thin films. The sensor features a fork-shaped housing with a 30 mm width and a 33 mm depth, housing a transmitter and receiver that emit and detect ultrasonic pulses, respectively. When material enters the fork opening, it attenuates the ultrasonic signal, allowing the sensor to determine the material's position based on the degree of attenuation. The bks-3/CIU offers analog outputs of 0-10 Vdc and 4-20 mA, providing flexibility for integration into various control systems. It operates on a voltage supply of 20-30 Vdc and is housed in an aluminum casing with an IP65 protection rating, ensuring durability in industrial environments. The sensor's response time is 2.5 ms, with a repetition rate of 2 kHz, making it suitable for high-speed applications. Additionally, it includes a teach-in button for easy calibration and LED indicators for center position and deviation detection. This sensor is part of Microsonic's bks series, known for their precision and reliability in web edge control applications.
