Sick UFN3 Series Ultrasonic Slot-Style Ultrasonic Sensor, 3 mm Detection, NPN Output, 10 → 30 V dc, IP65

The UF ultrasonic sensors reliably detects labels and materials, regardless of printed design, transparency or surface characteristics. Unlike optical sensors, the UF3 relies on damping – a process where the thickness of a material determines the degree to which the sensor absorbs sound waves. A high level of positioning accuracy and stable response times make the fork sensor suitable for nearly any environment. Due to its small, compact metal housing, the UF can be used in harsh conditions and where spaces limited. As a result, the UF3 can distinguish between labels located just 2 mm apart from one another on an adhesive tape.

Applications include detecting transparent labels on transparent substrates, detecting labels with different printed designs or differentiating between single- and two-ply materials.

Detection of transparent, opaque or printed labels
Unaffected by metallic foils and labels
Fast response time of 250 μs
Simple and accurate adjustment via teach-in button, or plus/minus buttons
Rugged, IP 65 aluminium housing

Great flexibility: UF identifies labels reliably - regardless of whether they are transparent, opaque or printed
Fast response times enable precise detection – even at high web speeds
Teach-in function enables quick and easy commissioning
The aluminium housing meets all requirements for use in harsh industrial conditions
High process reliability: Ultrasonic technology prevents false detection, which may be caused by ambient light or shiny surfaces

Detection of transparent, opaque, or printed labels
Double sheet detection
