Honeywell 103MG5 HCS Magnetics for Hall-Effect Sensor Applications
The Honeywell 103MG5 HCS Magnetics part belongs to Honeywell’s MG Series magnet portfolio and is intended for use as an actuator with Hall-effect and magnetoresistive sensor ICs. In magnetic sensing design, the magnet is not a secondary accessory. It is a core performance element that directly influences activation distance, signal stability, and overall sensing behavior.
Technical Characteristics of Honeywell 103MG5 HCS Magnetics
Honeywell’s MG Series documentation describes the family as a range of compact magnets offered in different materials, shapes, and strengths to help engineers match the right magnetic field to a sensing requirement. The Honeywell 103MG5 HCS Magnetics model is identified as a rare earth pressed square magnet with dimensions of approximately 1.98 mm x 1.98 mm x 1.02 mm. The series documentation also places it in a temperature-capable group up to 200°C, depending on part design and application conditions.
That compact size is important because many sensor assemblies need a strong magnetic field without sacrificing installation space. In those cases, a small rare-earth magnet can be a practical engineering solution.
Where the Honeywell 103MG5 Magnet Fits Best
The Honeywell 103MG5 HCS Magnetics magnet is relevant in applications involving door and lid position detection, equipment home-position sensing, drawer monitoring, compact motion systems, and speed or RPM detection when paired with the appropriate sensor. MG Series literature also highlights industrial and medical use cases, including hospital equipment and electronically controlled containers.
Because the magnet affects how reliably a Hall-effect sensor actuates and releases, choosing the right geometry is essential. A magnet that is too weak or poorly matched to the sensor’s operate point can create unstable switching behavior, while a correctly selected magnet supports cleaner and more predictable detection.
Why Honeywell 103MG5 HCS Magnetics Matters in Design
When engineers search for Honeywell 103MG5 HCS Magnetics, they are usually solving a system-level question: how to achieve dependable magnetic actuation in a very small footprint. That is where the MG Series stands out. It is not just a generic magnet offering; it is a sensor-oriented magnet family with published guidance intended to help match field strength to sensing requirements.
