CNA1015 Photo Interrupt Module
A photo interrupter sensor that consists of a light-emitting element (IR LED) and a light-receiving element (phototransistor) aligned facing each other. It works by detecting light interruption when a target object comes between both elements, acting as an optical switch. This changes the output of the sensor.
Features
- Wide voltage LM393 comparator.
- Operating voltage: 3.3V ~ 5V.
- Active low output i.e an interruption produces a low output (LED is activated).
- Maximum output sink current: 10mA.
- 5mm slot width.
- Two (Ø 3.5mm) mounting holes for easy installation.
- Dimensions: 26mm X 21mm X 6mm.
