DIGITEN 0-99999 5 Digit LCD Digital Punch Counter with UP Gauge & Proximity Switch Sensor

cumple con lo esperado y es de facil implementacion

Good

brought to fit on a sentro knitting machine as counter had started to not tick over on row count ,easy to fit and set up . I used Velcro to attach so could use between two different machines, works and keeps count perfectly.

Muy rapido de instalar. Considerar adquirir baterias

First, this device works as advertised. There are connection instuctions in English (simple). Battery replacement is easy although lasts a very long time. The sensor is more sensitive than they say, maybe 1/2 - 3/4 inch and that is with their little button magnet. The stronger the magnet the greater the distance. A great deal since the hall sensor or the counter is worth the price alone. The provided sensor doesn't have to be used. Any switch, of any sort, will work. It is also very nice that they include that small bracket that holds the sensor and the sensor has a long threaded neck, with two nuts, that allow adjust the distance from the magnet after installation. They don't mention but to reset the counter, you can used an attached switch or just press the pause button a couple of times. See the attached picture for my application where I count the revolutions of the rear tire of my lawn tractor (I just snapped the button magnet on the tire rim (two magnets would give two counts per revolution). It bounces around quite a bit but that doesn't phase the sensor. They provide a bracket for mounting the counter or you can use a another magnet. Just remember that this is not a high speed counter, maybe 10-20 counts per second or 600-1200 rpm and depends to some extent on the strength of magnet and sensing distance. In addition, it only counts up since the sensor can't tell whether the magnet is coming or going.
