█ITR-20402 Opto Interrupter Descriptions
The ITR20402 consists of an infrared emitting Diode and a silicon phototransistor encased in a black Thermo-plastic housing. The advantage of the device is the small package. Phototransistor receives radiation from the IRLED only, and avoids the noise from ambient light
