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 l
c
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 (l
