Pepperl+Fuchs UGB-18GM50-255-2E1

Splice sensor

The UGB-18GM50-255-E1 is an ultrasonic joint sensor from Pepperl+Fuchs designed to detect joints and breaks in a variety of materials including paper, film, textiles and thin metal sheets. The sensor uses ultrasonic waves to detect changes in the acoustic impedance of the material occurring at the joint.

• Sensor frequency: 255 kHz
• Operating voltage: 18 ... 30 V DC, ripple 10% SS
• No-load current: < 60 mA
• Delay time before ready: < 500ms
• Input type: Educational input Level 0: -UB ... -UB + 1 V Level 1: + UB - 1 V ... + UB
• Pulse duration: ≥ 500 ms
• Impedance: ≥ 10 kΩ
• Output type: 2 output switches NPN, NC
• Rated operating current: 2 x 100mA, short circuit/overload protected
• Voltage drop: ≤ 3 V
• Turn-on delay time: ≤ 600 μs
• Off delay time: ≤ 600 µs
• Pulse extension: ≥ 120 ms programmable

Advantages:

• Insensitivity to print, color and shiny surfaces: The sensor can detect compounds on printed, colored and shiny materials that may be problematic for other sensors.
• Very high processing speed: The sensor can detect connections at a very high speed, making it ideal for use in high-speed applications.
• Suitable for joints with heterogeneous materials: The sensor can detect joints on joints with heterogeneous materials, such as wrapping paper.
