MachTach Gear Tooth Sensor Housing

This housing retains a MachTach Gear Tooth Sensor and cable making it easy to mount the sensor on your machine tool. This sensor allows the MachTach to measure the speed of a machine by monitoring a gear with up to 90 teeth. The MachTach is a machine tachometer that displays speed in RPMs, Surface Feet Per Minute and Surface Meters Per Minute. You may use this sensor with MachTach or other tachometers. This sensor requires a pull up resistor which is built into the MachTach. If you use another tachometer, you may have to add the pull up resistor to this PCB. See www.machtach.com for more information I've included the PCB design file which can be manufactured at http://www.expresspcb.comThe cost is $75 for 75 boards. Yes 75! That's not a typo. This board is so small they can only economically make them with 25 to a board and the minimum order is 3 boards for $75.
