Datasensing DG Photoelectric Sensors with UR remote amplifiers are recommended for the vehicles detection in washing and drying tunnels, either for cars or even trucks and trains. Vehicle washing plants are characterized by high-pressure water jets, which on the one hand put a strain on electronic devices and on the other complicate detection by photoelectric sensors. DG through beam sensors, thanks to IP69K protection degree on optics and sensing distance up to 75 m, guarantee the vehicles detection through high pressure water jets and dense clouds of misting water.UR control unit is used to interface DG sensors with the washing plant automation, offering 24 Vac or Vdc power supply, 250 Vac 3 A NO-NC relay output and NO alarm output, with adjustable timing function.
