RPR220 Reflective Optoelectronic Sensor Module - Photo Transistor Output
The RPR220 is a reflective optoelectronic sensor module integrating an infrared LED and a phototransistor for proximity and surface detection within a 1-13mm range. It operates on a wide DC voltage up to 30V and is designed for direct PCB mounting in automation and consumer electronics.
Features
- Reflective infrared sensor with integrated IR LED and phototransistor.
- Detection distance range of 1mm to 13mm from the reflective surface.
- Wide operating voltage range up to 30V DC for flexible power supply integration.
- Photo transistor output capable of sinking up to 30mA maximum current.
- Compact black plastic housing with a 4-pin through-hole footprint for easy PCB mounting.

The RPR220 reflective optoelectronic sensor operates on the principle of infrared light reflection. The integrated infrared LED emits light, which is then reflected off a target surface and detected by the adjacent phototransistor. The output signal from the phototransistor varies based on the intensity of the reflected light, allowing for proximity detection, line following, or surface color discrimination.
Designed for reliability in automated systems, its plastic lens provides focused sensitivity, making it suitable for integration into space-constrained applications like optical encoders, paper detection in printers, and object sensing in vending machines. The module’s straightforward interface requires only power and a pull-up resistor for the open-collector output.
