1. Overview
1.1 input pulse signal: NPN / PNP open collector, contact switches, non-contact switch, limit switch, etc. level pulse.

1.2 input voltage: high H = 4 ~ 30V, a low level L = 0 ~ 0.6V, falling edge triggered

1.3 Measurement range: 0 to 9999 counts up

1.4 count input frequency: less than 2000Hz

2, the characteristics of
2.1 exhibits a high word : 0.56 "high brightness the LED

2.2 power: voltage 5V ± 10% the DC ; current is less than 80mA (other voltage, such as 9V, 12V, 24 etc. indicate when ordering)

2.3 working temperature: -10 ~ 60 ℃ (relative humidity 80% or less)

2.4 dimensions: 43 is 79 × 25mm ×

2.5 mounting hole size: 75 × 39.5mm

4, the working demonstration:

 In operation, let  the magnet close to the magnetic proximity switch from 0.5-1 cm, and then let the magnet  away from magnetic proximity switch a certain distance (typically 3-5 cm), the counter counts plus 1, repeat the process, the accumulated counter is count : 0,1,2,3,4,5,6 ...... (Note: the magnet close to the count) .

5, Attention:

  a, the count signal and the clear signal input switch or circuit counter should be as close to the terminal of the counter, the signal line as short as possible

 B, such as to avoid the other: the strong electric power wires or twisted wires or tubes and the like with traces, in order to avoid unnecessary interference, use shielded wires if necessary, shield connected to the "+" terminal of the counter.

  C, is not recommended to use a mechanical switch or micro switch , because of their relatively short life lot, after a long time be easily mistaken count; when such mechanical switches or micro-switches, try the mass little better, so as to avoid counting Qiang Lie recommended MagSwitch
