BARTINGTON INSTRUMENTS 1. About this Manual This manual provides the information necessary to help Mag646 customers connect, install and operate, the Mag646 magnetic field sensor. Technical specifications of the products, including power supply requirements and analogue output details, can be found in DS3836, while outline drawings of sensor head, electronics board...
BARTINGTON INSTRUMENTS 3. Introduction The Mag646 is an unpackaged single-axis fluxgate sensor that provides highly linear magnetic response and low hysteresis. The sensor consists of a single, feedback-stabilised, fluxgate sensing element arranged along one of two directions, in line with the PCB or perpendicular to the long side of the PCB.
Caution: When providing your own power supply, do not exceed the voltage rating, provide sufficient current, and ensure correct polarity is respected, see DS3836. Caution: Connect the Mag646 electronics board before the supply is energized, as this prevents high surge currents which could cause damage.
BARTINGTON INSTRUMENTS 6.2. Electromagnetic Compatibility Note: The Mag646 sensors are not shielded for immunity from, or emission of, electromagnetic fields. Note: The Mag646 sensors are intended for integration into other systems. Ensure these meet the appropriate level of shielding. 7. Troubleshooting The sensor is unlikely to suffer any defects in normal use: no internal components are serviceable.
(at least twice the breakthrough frequency). 8. Care and Maintenance Surface dirt contamination on the Mag646 probe should be removed using a mild detergent solution only. Electronics should be cleaned with an antistatic cloth only. ESD protection should be used when handling the Mag646 electronics board, to prevent irreparable damage.
