Bulk Indium Arsenide BH-200 Series
Instrumentation Quality
Description
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 (-Ic), AWG 36-neutral (+lc), green (-lc)
d. Hall Voltage: (VH): AWG 34-blue (+VH), yellow (-VH), AWG 36-red (+VH), neutral (-VH)

BH-201 Ultra-thin, Transverse
BH-202 Small Axial
BH-203 General Purpose, Axial
BH-204 Mini Axial
BH-205 Mini Transverse

BH-207 High Resolution, Tangential
BH-209 Ultra-mini, Transverse
Electrical Specifications
*Approximate
NOTE: In a time varying field the voltage induced into the Hall output
leads, Vind, is proportional to the effective area, A, of the Hall output loop
and the amplitude and the rate of change of the field, Vind (measured with
Ic=0)=A dBdt x10-8
Vind=volts, A=cm2, B=gauss, t=sec.
