MachTach Gear Tooth Sensor Housing

thingiverse

This housing features a MachTach Gear Tooth Sensor and cable, making it simple to attach the sensor to your machine tool. The sensor allows the MachTach to measure the speed of a machine by monitoring a gear with up to ninety teeth. The MachTach is a machine tachometer that displays speed in RPMs, Surface Feet Per Minute, and Surface Meters Per Minute. You can use this sensor with the MachTach or other tachometers. This sensor requires a pull-up resistor, which is built into the MachTach. If you are using another tachometer, you may need to add the pull-up resistor to this PCB. The sensor can be mounted facing inline with the housing or perpendicular so that you can mount the house in the same plane as the gear you are sensing or perpendicular to the gear.

The cost is seventy-five dollars for 75 boards. Yes, that's not a typo! This board is so small that they can only economically make them in quantities of 25 per board, and the minimum order is three boards for $75. I have recently added printed covers that can be glued into place to seal the housing. One style is for the vertical mount, and the other is for the horizontal sensor mount.
