LED Tachometer Hall Proximity Switch Magnet Sensor 4 Digit Red RPM Speed Meter NPN for Ship Distribution Box Control

Feature: 1. STABLE POWER SUPPLY: The LED tachometer hall proximity switch magnet sensor supports a wide voltage input of 40mA and is compatible with various power supply environments such as vehicles, industrial equipment, and small machinery. No additional voltage regulation is required. Can be used immediately upon connection, which is more worryless 2. UNIVERSAL INSTALLATION: The RPM speed meter hall proximity switch magnet sensor adopts a universal installation specification of 22mm and can be directly embedded in standard openings such as distribution boxes and control cabinets without additional modifications, which is more convenient to replace traditional indicator lights or small instruments 3. HIGH DEFINITION DISPLAY, COMPACT AND SMALL: The tachometer is equipped with a 0.56in screen and a red 0.2in LED four digit digital tube. The numbers are eye catching and easy to read. Even in strong light, the rotational speed data can be clearly recognized, which is small and does not take up much space, and is easy to install 4. ACCURATE MEASUREMENT: The LED tachometer RPM speed meter NPN data is accurate and reliable, with a measurement accuracy of + 0.1percent . The measurement range covers 30 9999RPM, meeting the speed monitoring requirements of most rotating equipment such as motors, fans, and wheels. The accuracy far exceeds that of ordinary tachometers 5. INTELLIGENT PROMPT, SAFER: 4 digit LED tachometer hall proximity switch magnet sensor with out of range recognition function: When the speed is below 30RPM, it shows 0000; when it is above 9999RPM, it shows High. This intuitively indicates that the equipment rotational speed is abnormal, avoiding operational errors caused by ambiguous readings Specification: Item Type: LED Tachometer Hall Proximity Switch Magnet Sensor Working Voltage: DC 40mA Display: 0.56in red LED screen, 4 digit reading Measurement Range: 30 9999RPM Measurement Accuracy: + 0.1percent , reading + 1 digit Overflow Display: Below measurement range, display 0000 ; beyond measurement range, display High LED Size: 0.2in Installation Specification: Approx. 22mm 0.87in . Package List: 1 x RPM Speedometer 1 x Switch 1 x Switch Accessory
