Vishay Triple-Channel Transmissive Optical Sensor 

Vishay's TCUT1630X01 is a three-channel transmissive sensor, also called a photo interrupter. It can be used to detect not only the speed and direction of an encoding wheel but can also detect a vertical push function. The push function is made possible by the addition of a third phototransistor and a slightly deeper channel. Great for turn and push knobs like the radio volume knob or climate control knobs in your car. The TCUT1630X01 provides a 3mm gap to accommodate various types of code disks, strips, and wheels, and it has a typical collector current of 1.3mA per channel. The device is AEC-Q101 qualified, with a maximum junction temperature of 110°C, and can be used in cabin interior automotive applications as well as in industrial applications.
