Pulse Counter

1. What Is A Pulse Counter?

A pulse counter is an instrument used to count the number of pulses in a given period of time.

It can count pulses from either the rising or falling edge of the pulse.

Our pulse counters can be used to count voltage pulses, voltage-free pulses (e.g. button presses, micro switch closures, etc.) or transistor output pulses.

2. How Many Types Of Pulse Counters We Provide?

According to the different working modes, pulse counters can be divided into mechanical pulse counters, electromechanical(electromagnetic) counters and digital pulse counters.

Mechanical and electromagnetic pulse counters use a counting wheel to indicate the number of pulses, while digital pulse counters use an LCD display or LED tube to display the counting result.

Lorentzzi® can provide both types of them, our typical electromechanical counters are CSK6-YKW 6 digits counter, CSK4-YKW 4 digits counter etc, our typical digital counter is H7EC-N 7 Digits No Input Voltage Counter, JDM11-6H counter etc. 

In addition, we can also provide preset counter relays such as JDM9-6 preset counter relay, DH48J preset counter relay, ZN48 preset counter
etc, which are used to perform certain actions when the count number reaches the preset value.

3. How to Use a Pulse Counter

Different counters have different operating modes.

Generally, our pulse counter needs to be used in conjunction with a no-voltage switch, a voltage pulse signal, or a proximity sensor.

If it is a proximity switch, it doesn’t matter whether the proximity sensor is inductive, capacitive, or photoelectric.

When an object enters the sensor’s sensing range, the pulse counter will record one time.

Alternatively, you can use this pulse counter in conjunction with a no-voltage switch or circuit breaker to count the number of times it is pressed.

4. How Pulse Counters Work

Pulse counters work by taking an input signal and counting the number of transitions from one state to another within a specified time. They can be set to count up or down depending on the application.

5. Pulse counter Applications

Pulse counters can be used to count product quantities, batches, and perform routine equipment maintenance.

Preset counters can perform operations such as issuing alarms, cutting off power, and sending completion signals to other devices after a specified number is reached(you can learn more about the differences between the two types of counters in this article: Totalizing Counters vs Preset Counters: What Are the Key Differences?).

You can also use it with a preset count relay with a pulse counter for batch counting. For more details, you can read this article: How To Wire an Electromagnetic Counter to a Repeat Cycle Timer Relay?.

In terms of specific applications, pulse counters can be used in game consoles to count coins, lightning rod counting devices, laser equipment etc.
