New sensor for autofocus installed.

Postby Techgraphix » Sat Sep 12, 2015 1:45 pm

After years of using a proximity-sensor with a metal reference block, i could lay my hands on a Ultrasonic sensor UB300-12GM-E5-V1.
This sensor has a Teach-in input where the distances of the trigger-gate can be set: connecting it to +24V for longer than 1 sec and the furthest distance is set. Connecting it to GND for longer than 1 sec and the closest distance is set.. Between those two the output is low.
I used a small self-centering toggleswitch to program the sensor.
almost all material gives the same distance within ~0.2mm except a thick layer of felt.. but when i lay a piece of paper on it, it's ok too..

On the pictures you can see the switch and the new aluminum bracket that i made for it..
