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
基于霍爾效應，當電流垂直于磁場方向通過半導體基片時，載流子受洛倫茲力作用產(chǎn)生橫向電勢差（霍爾電壓）。HJ-2S通過內置霍爾元件捕捉該電壓變化，經(jīng)差分放大和施密特觸發(fā)器處理后輸出規(guī)整電信號。傳感器對N極磁場敏感，觸發(fā)閾值穩(wěn)定，響應頻率可達數(shù)千赫茲，適用于高速計數(shù)和動態(tài)測量。其無觸點設計消除了傳統(tǒng)機械開關的磨損問題，特別適合長期連續(xù)作業(yè)場景。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
