As a leader in infrared system solutions, Vishay Telefunken has developed a new rain detector in cooperation with ITT Automotive. The TSRF900 is designed for use in rain-sensor systems in automotive applications. The unique system design detects the reflected infrared transmission from the windscreen surface by applying the different reflections of wet or dry windscreen surfaces. The detector system is built onto a pc-board that contains the emitting and detector chips and is covered with a special plastic hood in which the optical system is implemented. This special flat design enables a second pc-board to be implemented for the control circuitry allowing it to fit easily into the foot of the rear mirror.
Samples are available now.
