DIGITEN DC 12V 4 Digital Red LED Counter Meter Up Down+Hall Proximity Switch Sensor NPN

Added this to a mini lathe to be able to set the 'sweet' spot on the speed for frequent projects.

Instructions were clear and unit worked perfectly first time. I used the unit to count rotations of the anchor windless so as to know the amount of anchor chain that is paid out. This unit came with a nice quality hall effect proximity sensor. The counter has independent up and down count inputs. Connect the sensor, via a SPDT toggle switch to select when counting up or down. A reset switch or button is also needed.

I bought two of these for a putting green and am installing them to count attempted or made putts. In the testing phase, the first one I tried would come on but the switch would not activate. The second one worked great. I have a plethora of hall sensors and can wire one up that works, but quality testing must be one of those things they scrimp on to keep the price low.

Insufficient information for buyer to know all that will be required before this counter will function.

This counter works well in my application. Easily set up . Although I give this product 4 stars there are two things that I would change. First the magnet for the sensor is not very strong. Also this unit does not have a reset switch included. Which i knew prior to purchase.

Created counter for maxiclimb exercise machine. Perfect.

I have this item and it works perfectly. I got it three years now and still working very well. I use it as a bobbin thread counter for my sewing machine.

This counter works well but it didn't last long at all; maybe 4 hours total usage time. You would think that in today's electronics an item would last a loooong time. But this one does not. I ordered another one so I can have something in the meantime while I find a better counter.EDIT: Just received another one thinking the one I had was just a bad one. The new one is no better! They say it is good for 100 Hz but I can only get it to operate reliably up to 16.6 Hz. Anything over 1000rpm it stops counting.
