DIGITEN DC 12V 24V 4 Digital Blue LED Counter Meter Up Down+Hall Proximity Switch Sensor

Met my needs and was on time

Excellent ... very well made and quite accurate.

works great

What the heck is this??? Second time, same item?!??!??!

The Counter itself is great and allows upwards, downwards counts and resets to zero. Reason I gave it 3 stars, the counter requires a positive signal from a PNP, NO sensor, because it needs a positive impulse to count (up or down). But the sensor included in this package is a NPN,NC type. Means, this sensor can never work with this counter, because: a:) it switches minus, but the counter needs a plus impulse b:) it is NC (normally closed), and should be normally open, only close to give impulse Ironically, the instructions for the counter even specify the use of other sensors as long as they are PNP, NO type. I suppose, somebody really slept when they put the counter/sensor package together. I've ordered 2 of this counters and they both came with wrong sensor type. With PNP, NO sensors the counter works flawless.

It seems nice. I like the blue color of the counter. However, as another reviewer mentioned, it ships with the incorrect sensor. This requires a PNP NO (NKJ-5002C) sensor but ships with an NPN NC (NKJ-5002O). Maybe the fact that the sensor manufacture uses the "C" designation for the normally open model and the "O" for the normally closed model is causing some confusion somewhere along the way. Expect to spend another $10 to replace the sensor with the correct one.

Buen servicio

Study purpose

説明書通りに配線してしっかり反応しました。 センサーに反応させようとしたものがうまく出来なかったので赤外線のセンサーにすると反応しました

Does exactly what I wanted
