Bulk Indium Arsenide BH-200 Series Hall Sensors Instrumentation Quality The BH-200 series of Hall effect magnetic field sensors consists of ten models designed to meet the requirements of most magnetic field measurement applications. Models in the BH-200 Series are built in various configurations to measure axial, transverse, and tangential magnetic field components. Sensitivities range from 6 to 75 mV/kG with input and output resistance of several ohms. Mechanical Specifications a. Polarity: With the magnetic field vector (+B) entering the top of the Hall plate and lc entering the red lead, the positive Hall voltage will appear at the blue lead. b. Material: AWG 34 or AWG 36 copper with heavy polyurethane insulation. c. Color Code: Control Current (lc): AWG 34-red (+lc), black (-lc), AWG 36-neutral (+lc), green (-lc) d. Hall Voltage: (VH): AWG 34-blue (+VH), yellow (-VH), AWG 36-red (+VH), neutral (-VH) BH-200 General Purpose Transverse BH-203 General Purpose, Axial BH-206 High Sensitivity, Low-cost Transverse BH-207 High Resolution, Tangential Electrical Specifications NOTE: In a time varying field the voltage induced into the Hall output leads, Vjnd, is proportional to the effective area, A, of the Hall output loop and the amplitude and the rate of change of the field, Vjnd (measured with Vjnd=volts, A=cm2, B=gauss, t=sec.
