Working principle and introduction: The 711A pre selection electronic counter is the latest counter developed by our company for the Chinese market based on the 711 pre selection electronic counter from Huntsler, Germany. It uses highly integrated surface mount components, occupies small space, has strong counting function, and can be driven by signals such as voltage pulses, proximity switches, photoelectric switches, shaft encoders, or mechanical contact switches for counting. The counting frequency is high. This counter can be reset by both the front panel and external electrical signals, making it easy to use. Its unique internal memory can store the count value for ten years without the need for batteries after power failure or shutdown. 6-digit red digital tube (LED) display, high clarity, easy identification, not easily affected by temperature and light, can be used for intermittent zeroing counting work, such as statistical counting, mechanical rotation, currency counting, flow counting, group selection counting, etc. It is widely used in industries such as packaging, spinning, machinery, printing and dyeing.
