AJMRTC 20Pcs ITR9608 ITR9608F DIP-4 Photo Interrupter Sensor, Slotted Optical Optocoupler Infrared Beam Break Sensor for Counting, Speed Detection, Arduino Electronic DIY

AJMRTC ITR9608 photo interrupter is a widely used slotted optical sensor for electronic prototyping and industrial auxiliary detection. It contains an infrared emitting diode and a phototransistor mounted face-to-face inside the U-shaped slot. When a thin object passes through the gap and blocks the infrared beam, the phototransistor changes its conduction state to produce a detectable switching signal. No complicated peripheral circuit is required, and it can be matched with LM393 comparator or directly read by MCU IO port. The DIP-4 through-hole package is convenient for hand soldering on custom PCBs and fits standard breadboards. This sensor is commonly used for rotary speed measurement, pulse counting, paper detection, limit position trigger, encoder sensing and automatic induction circuits. It works perfectly with Arduino, STM32, ESP32 and other microcontrollers. Each package includes 20 pieces to meet multi-channel testing, batch production and spare replacement needs.
