We are currently using a rotary encoder that provides 200 pulses per revolution to a programmable 6-digit LED display (Crouzet CTR24L) to measure the distance and speed for a cable installation device. While this combination works very well with our prototype, we need to reduce the size of the display. The Crouzet CTR24L is is the smallest display I can find on the market. We only need a 4-digit LED or backlit LCD display. I thought if I can separate the display from the logic portion of the display I could place them in the enclosure in such a way to reduce the overall size of the enclosure. Can someone help me with identifying a 4-digit LED or backlit LCD display along with a logic board that we can program to give us distance and rate in Ft. & Ft./Min. or Meters & Meters/Min. with the signal we are getting from the rotary encoder similar to the Crouzet display?
