Digital Tach case and mount
thingiverse
I am building a 2" X 72" belt sander/grinder and this Tachometer will show me the speed of the belt. I added a back and pivot mount so it could be mounted in a standing or hanging, or from behind just install the module in the case orientated as you like. The Digital Tachometer has a push in type attachment so there is a thin lip inside the front edge which give it a tight fit. The back cover is a tight fit and may require a small amount of sanding to the inside edge where the back attaches. I wanted a full cover to keep any dust from getting to the electronics. There is a hole in the back for the cables to exit. The digital Tach was bought from eBay. https://www.ebay.com/itm/1PC-4-Digital-LED-Tachometer-RPM-Speed-Meter-Hall-Proximity-Switch-Sensor-NPN/132553574576?ssPageName=STRK%3AMEBIDX%3AIT&var=431904489837&_trksid=p2060353.m2749.l2649
