CNA1015 Photo Interrupt Module

From the shop's description

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. Specifications Parameter Value Operating Voltage 3.3V – 5V Output Type Active-Low Max Output Sink Current 10mA Slot Width 5mm Position Detection Accuracy ≈ 0.3mm Mounting Holes Two, Ø 3.5mm Dimensions 26mm × 21mm × 6mm Optical Elements GaAs IR LED & Phototransistor Applications Object or shaft passage detection in robotics and automation. Counting, stopping, or alignment sensors in conveyor and machine systems. Contactless optical switches in DIY and embedded electronics. Prototyping and educational electro-optical sensor learning modules. Package Contents 1× CNA1015 Photo Interrupt Module.
