Item Type: Digital Electronic Counter Product Model: BEM-04NK-L-CT Counter Model: JDM11-6H Power Consumption: 10W Counting Range: 1-999999 Counting Speed: 10 times/s Working Method: Continuous working system Counting Method: Contact count, level count and sensor count Operating Temperature: -5-45 Storage Temperature: -20-70 Reset Time: 0.5s Power Restart: 1s Sensing Distance: Approx. 4mm / 0.2in Detection Object: Metal object Reset Method: Panel reset Counting Error: 1 Data Retention: 10 years Power Cord Length: Approx. 1.5m / 4.9ft Sensor Cable Length: Approx. 1.8m / 5.9ft Application: Widely used in petroleum, chemical, textile, machinery, mining, national defense, agriculture, food, printing and other industries; but for the control of valuable equipment or the situations where the product is damaged and safety is endangered, please do a secondary protection. Working Principle: The sensing distance is 4mm. When metal object passes through the sensor, it starts counting. How to Use: The contact input should be reliable to avoid malfunction caused by contact bounce. Reset Function: Press the panel reset button at any time. The counter returns to the initial state, and the reset time is 0.5 seconds The maximum speed of the calculator is the maximum speed when the duty ratio is 1: 1, and the pulse width of on or off is greater than 50 milliseconds. In the control system, the counter control line is wired separately from other power lines; in a strong current environment and the counting terminal wire is long, please use a shielded wire.
