If I have the sensor mounted on the toolhead and shining down, with a chuck and a bit in between, two inches might be alright. Adafruit has another breakout that only measures between 5 mm and 200 mm.

Question for you sensor experts... I'm looking to do a project that would involve detecting when an item passes through a doorway near ground level (~6 inches above ground level). Doing a bit of ...

The CLI700 reflective object sensor consists of an 880-nm aluminum-gallium-arsenide (AlGaAs) infrared emitter and an npn, buffered, open-collector IC. Both are mounted on a custom, four-leaded TO ...

Operating at distances from 2 mm to 40 mm, the 6 mm x 3.76 mm x 3.9 mm, surface-mount TCND5000 reflective optical sensor integrates an IR emitter and PIN photodiode in a single ...
