AI Overview
An NPN input counter is a digital counting device that receives signals from sensors (like proximity or photoelectric sensors) that switch to ground (0V) when activated, commonly referred to as "sinking" or "NPN" sensors. They are widely used for counting, batching, and totalizing in automated systems, requiring a positive common terminal for the input signal.

What is an NPN input?
Learn the basics about sourcing and sinking sensors
When wiring a sensor, the “N” stands for “Negative” and the “P” stands for “Positive.” An NPN device can switch the negative side of the circuit, while a PNP device switches the positive side.

What is a counter input?
The counter counts the number of rising (or falling) edges occurring on the Source input between two edges of the Gate signal. You can calculate the high and low time of the Gate input by multiplying the period of the Source signal by the number of edges returned by the counter.
