Product Introduction of HJ-2S Hall Effect Sensor
The HJ-2S is a magnetic sensing device utilizing the Hall effect principle, where a voltage differential (Hall voltage) is generated when current flows through a semiconductor material under perpendicular magnetic field. Featuring compact design with IP-rated enclosures in ABS, stainless steel or aluminum alloy, it offers reliable operation in harsh environments. The sensor provides digital switching output with configurable logic (NPN/PNP, NO/NC) for seamless integration into automation systems. Its non-contact detection mechanism ensures long service life without mechanical wear. The product incorporates visible LED status indication and supports both cable outlet and connector interface options. Optimized for speed monitoring on conveyor belts, position feedback in machinery and rotary encoding applications, the HJ-2S demonstrates consistent performance across temperature variations through precision signal processing circuitry. 21318
核心工作原理
基于霍尔效应，当电流垂直于磁场方向通过半导体基片时，载流子受洛伦兹力作用产生横向电势差（霍尔电压）。HJ-2S通过内置霍尔元件捕捉该电压变化，经差分放大和施密特触发器处理后输出规整电信号。传感器对N极磁场敏感，触发阈值稳定，响应频率可达数千赫兹，适用于高速计数和动态测量。其无触点设计消除了传统机械开关的磨损问题，特别适合长期连续作业场景。91518
Technical Specifications
Operating on DC 4-25V power supply with ≤20mA current consumption, the HJ-2S achieves magnetic sensitivity of ≥50mT. The output delivers clean switching signals compatible with TTL/MOS logic circuits. Environmental resilience includes operation at -20℃~70℃ ambient temperature and 95% RH humidity resistance. The sensing distance varies with magnet selection (typically 5-15mm for standard ferrite magnets). Modular construction allows flexible mounting via M12 threaded housing or bracket fixtures. Typical applications include: speed detection in material handling systems, position feedback for automated equipment, and safety interlock mechanisms in industrial machinery. 41113
