IR beam-breakers are commonly used as a “gate” detector. Either a bar, slot or other IR-blocking mechanical device breaks the beam between the infrared emitter and detector, and the resulting signal is cleaned up and presented as a nice digital signal. It’s very quick too, and can be used to measure the pulses on slotted-disk tachometers.


  • U-Shape type optical coupling IR emitter and detector pair
  • Clear/Blocked state LED
  • Signal blocked is output HIGH, otherwise LOW
  • LM383 comparator IC cleans up noisy signals, and offers a robust 15mA logic-level drive output signal
  • Mounting holes


  • 10mm gap width
  • 3.3-5V Working voltage
  • Digital output
  • PCB size: 2.3 cmx2cm
