Infrared beam break (cut) detetor circuit (short distances)

  • Posted on August 6, 2011 at 2:45 am

Link to page: pcbheaven.com A very sensitive IR beam-cut detector pair, for small distances (up to 2.5cm – 1 inch). Can be used for rotary encoders, limit switches or other applications that require precision but no long distance beams. It can be fine adjusted to the point that it will not only detect a beam cut, but it will also detect semi-transparent objects such as plastic bags and other semi-transparent films.
