The unit works efficiently with systems that also use an \u003cstrong\u003enpn proximity sensor\u003c\/strong\u003e, and it can support applications requiring an \u003cstrong\u003einductive position sensor\u003c\/strong\u003e. With high accuracy, strong anti-interference ability, and stable readings, it fits perfectly into automation, testing setups, and industrial environments. This digital counter features a vivid LED display, excellent stability, and easy installation. It retains the count even during power loss and operates on AC\/DC 8–24V at 40mA. Designed for dependable performance, it is suitable for a wide range of digital instrumentation needs where a \u003cstrong\u003eproximity switch sensor\u003c\/strong\u003e setup enhances measurement precision.\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eTechnical Details\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eOperating Voltage: 8-24VDC\u003c\/li\u003e\n\u003cli\u003eDC Current: 30mA\u003c\/li\u003e\n\u003cli\u003eCounting Range: 0-9999\u003c\/li\u003e\n\u003cli\u003eMeasurement Range: 10-9999 RPM\u003c\/li\u003e\n\u003cli\u003eInput Voltage: Low (-30V to 0.6V), High (4-30V)\u003c\/li\u003e\n\u003cli\u003eColor Options: Blue, Green, Red\u003c\/li\u003e\n\u003cli\u003eSwitching Frequency: 320KHz (Hall NPN sensor)\u003c\/li\u003e\n\u003cli\u003eSupply Voltage: 5-24VDC, 6-36VDC (Hall NPN sensor)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eFeatures\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e4-digit bright LED light, clear to read.\u003c\/li\u003e\n\u003cli\u003eGood stability, high accuracy, and easy installation.\u003c\/li\u003e\n\u003cli\u003eThe counting value will be retained when power fails.\u003c\/li\u003e\n\u003cli\u003eWide application to automation equipment and test equipment.\u003c\/li\u003e\n\u003cli\u003eCompact size, attractive appearance with multiple color options.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003eHall NPN sensor\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eAppearance: M12mm cylinder\u003c\/li\u003e\n\u003cli\u003eOutput: NPN three wire normally open type\u003c\/li\u003e\n\u003cli\u003eThe detection distance: 10 mm\u003c\/li\u003e\n\u003cli\u003eSupply voltage: 5-24VDC,6-36VDC\u003c\/li\u003e\n\u003cli\u003eOutput current: 200 mA\u003c\/li\u003e\n\u003cli\u003eObjects can be detected: permanent magnets\u003c\/li\u003e\n\u003cli\u003eSwitching frequency: 320 KHZ\u003c\/li\u003e\n\u003cli\u003eWiring: brown- +Ve, blue- -Ve, black-signal\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch2 class=\"sing--sub-heading\"\u003e\u003cspan style=\"font-size: 18.72px;\"\u003eApplications :\u003c\/span\u003e\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMotor Speed Measurement\u003c\/strong\u003e – Ensures accurate RPM detection when paired with a \u003cstrong\u003eproximity switch sensor\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIndustrial Automation\u003c\/strong\u003e – Works effectively with rotating machinery and systems using an \u003cstrong\u003enpn proximity sensor\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConveyor Belt Systems\u003c\/strong\u003e – Helps regulate speed and maintain operational stability with support from an \u003cstrong\u003einductive position sensor\u003c\/strong\u003e.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFan and Pump Speed Monitoring\u003c\/strong\u003e – Provides consistent speed tracking in HVAC and fluid systems.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePhysical Attributes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003eColor(Optional): Blue, Green, Red\u003c\/li\u003e\n\u003cli\u003eAppearance(Hall NPN sensor): M12mm cylinder\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"product_info\"\u003e\n\u003ch3 class=\"sing--sub-heading\"\u003ePackage Includes\u003c\/h3\u003e\n\u003cdiv id=\"p_info\"\u003e\n\u003cul class=\"pro-ds\"\u003e\n\u003cli\u003e1 x 4 Digital red measurement indicators tachometer\u003c\/li\u003e\n\u003cli\u003e1 x Hall NPN proximity sensor\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"KitsGuru","offers":[{"title":"Default Title","offer_id":43179708449020,"sku":"KG981","price":979.0,"currency_code":"INR","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0587\/2130\/4757\/files\/led-tachometer-4digit-rpm-display-front.png?v=1765430091","url":"https:\/\/kitsguru.com\/de\/products\/led-4-digit-red-display-indicators-tachometer-hall-proximity-switch-sensor-npn","provider":"KitsGuru","version":"1.0","type":"link"}
