以下是關于SNJ-603電子可逆計數(shù)器的產(chǎn)品中英文介紹：

SNJ-603電子可逆計數(shù)器是一款功能強大的工業(yè)級計數(shù)設備，其核心特點是具備加減可逆計數(shù)功能，能夠根據(jù)運動方向自動進行加法或減法運算。該產(chǎn)品采用進口單片微處理器集成電路，配備紅色LED數(shù)碼管顯示，顯示位數(shù)為6位，可清晰呈現(xiàn)計數(shù)值。它還支持斷電記憶功能，確保數(shù)據(jù)在斷電后仍能長期保存。

在技術參數(shù)方面，SNJ-603具有6位顯示容量（999999），計數(shù)頻率分為低速30次/秒和高速5000次/秒兩檔。輸入信號兼容雙路光電或電平信號（5-30V），并提供DC12V/0.1A傳感器供電輸出。其工作溫度范圍為-10℃至+45℃，濕度≤85%RH，能夠適應多種復雜的工作環(huán)境。

該計數(shù)器特別適用于既有前進又有倒退的計數(shù)場合，如繞制各種線圈、電線、電纜長度計量等。在實際應用中，它可廣泛用于線圈加工、薄膜分切、倉儲物流等領域，有效解決了傳統(tǒng)計數(shù)器在倒退操作時需手動修正的痛點。用戶可通過輕觸按鍵直接設置初始值和參數(shù)，操作界面簡潔直觀。當計數(shù)達到預置值時，可自動觸發(fā)繼電器動作，實現(xiàn)設備啟停或報警。

The SNJ-603 Reversible Electronic Counter is an industrial-grade counting device with a core feature of bidirectional counting. It can automatically perform addition or subtraction based on the direction of movement. Equipped with a single-chip microprocessor integrated circuit and a bright red LED display, the counter has a 6-digit display capacity, which can clearly show the counting results. Additionally, it supports non-volatile memory, ensuring that data is preserved even during power outages.

In terms of technical specifications, the SNJ-603 has a 6-digit capacity (999999) and offers dual-speed counting modes, with a low-speed setting of 30 times per second and a high-speed setting of 5000 times per second. It accepts dual-channel photoelectric or level input signals (5-30V) and provides a DC12V/0.1A sensor power output. The operating temperature range is from -10℃ to +45℃, with a humidity level of ≤85% RH, making it suitable for various complex working environments.

This counter is particularly suitable for counting applications involving both forward and backward movements, such as coil winding and cable length measurement. In practical applications, it is widely used in coil manufacturing, film slitting, and warehousing logistics, effectively solving the problem of manual correction required by traditional counters during reverse operations. Users can directly set initial values and parameters via tactile buttons, with an intuitive and user-friendly interface. When the count reaches the preset value, the relay action is automatically triggered, enabling equipment control, start/stop functions, or alarms.
