What is it?

The E660 is a 6-digit electro-mechanical counter. It is a reliable and versatile counting device designed to accurately tally and display numeric values in various industrial and commercial applications. This compact and robust counter combines the precision of electronics with the durability of mechanical components to provide a dependable solution for tracking and monitoring purposes. Note: This counter can only count upwards, but not downwards.

Using this counter is straightforward as it features only three pins:

• VIN: (5V) The custom circuit board offers a built-in voltage step-up converter, increasing the 5V input to 24V required to drive the counter.

• CNT: Count - when this pin detects a falling edge, it increments the counter by one

• GND

To employ the counter, connect these three pins as described. To increase the counter by 1, transmit a single falling-edge pulse. If you wish to advance the counter by 8, send 8 falling-edge pulses, and so on. Allow 20+ milliseconds delay between pulses. Watch the demo video provided below. It showcases the electro-mechanical counter connected to an Arduino Micro Pro. A rotary encoder is utilized to select the desired increment, displayed on a separate OLED screen. By pressing the rotary encoder's button, you can increment the electro-mechanical counter by the chosen amount.

Electro-mechanical counters offer several advantages over other counting technologies, such as digital counters. Here are some of the key advantages:

• No Power Dependency: They don't rely heavily on electrical power sources, making them suitable for remote locations or situations where power supply is limited or unstable. These electro-mechanical counters will not lose their count during power failures, or from electrical noise.

• Physical Feedback: The tactile and satisfying audio feedback provided by the mechanical components can be useful in some applications, allowing operators to feel the counting action and confirming that each count has been registered.

• Durability and Longevity: Electro-mechanical counters are known for their robust construction and mechanical components, making them highly durable and capable of withstanding harsh industrial environments. They tend to have a longer lifespan compared to purely electronic alternatives.

• Reliability: These counters are highly reliable because they are less susceptible to electronic failures or glitches. They can continue functioning even in situations with power fluctuations or electrical interference.

• Accuracy: Electro-mechanical counters provide precise and consistent counting results. They are less prone to errors caused by electronic noise, calibration issues, or digit rounding.
