mag-03 Three-Axis Magnetic Field Sensors

Three-Axis Magnetic Field Sensors

Product model:mag-03


Product classification:Magnetic field measurement

These compact, high performance fluxgate sensors with integral electronics provide precision measurements of static and alternating magnetic fields in three axes.
They are available in a variety of enclosures. Powered from any ±12V supply, outputs are in the form of three analogue voltages from 0 to ±10V, proportional to Bx, By and Bz.
The sensors have a very wide range of applications in physics, bioelectromagnetics, geophysical exploration,and defence
A range of power supply and data acquisition units are available

Product name Package Noise specification* Range in µT
Mag-03 MC= Cylindrical
MCFL = Cylindrical, connections via flying leads
MCUP = Cylindrical, unpackaged
MCTP = Cylindrical, two-part construction
IE = Independent elements
IEHV = Independent elements, for use in a high vacuum
MS = square section
NC = no con
B – Basic
L – Low
Standard – no letter

Example: Mag-03MC100 is a standard noise sensor with a range of ±100µT.
* If no “L” is specified then the sensor is standard noise.
Note: For some Mag-03 magnetometers (Mag-03 MCFL, MCTP, MCUP, IE), lead lengths must be specified and this
length is included in the product identification. For example, Mag-03MCFL250-1000 is a Mag-03MCFL with a range
of 250µT and flying leads of 1000mm.
