B 5544 ulk Indium Arsenide BH-200 Sries Hall Sensors Instrumentation Quality Description The BH-200 sries 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 S驩ries are built in various configurations to measure axial, transverse, and tangential magnetic field components. Sensitivities range from 6 to 75 mVAG with input and output rsistance of several ohms. Mechanical Spcifications 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) Models BH-200 General Purpose Transverse BH-201 Ultra-thin, Transverse BH-202 Small Axial BH-203 General Purpose, Axial BH-204 Mini Axial BH-205 Mini Transverse BH-206 High Sensitivity, Low-cost Transverse BH-207 High Resolution, Tangential BH-209 Ultra-mini, Transverse Electrical Sp驩cifications *Approximate 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 lc=0)=Af xlO8 Vjnd=volts, A=cm2, B=gauss, t=sec. f SPECIFICATIONS UNITS BH-200 BH-201 BH-202 BH-203 BH-204 BH-205 BH-206 BH-207 BH-209 Input rsistance, Rj ohms 2.5 max. 3 max. 3 max. 3 max. 3 max. 3 max. 7 max. 2.7 max. 2.5 max.
