Design Assistance

BJA Magnetics Applications Engineering staff offer comprehensive design assistance.

Magnetic modeling: 2D and 3D analysis of your application, for example:
Design relationships for your Hall sensor and application specifications.
Complete analysis includes studying the effects of the operate and release point of the Hall sensors compared to the magnetic output waveform.
Switches and latches
Ratiometric / Linear Halls
Pulse counters
Complex holding force calculations.
Manufacturability analysis.

Boundary Element Analysis (BEA)

Complex devices can be modeled using boundary or finite element analysis.

Magnetic circuit analysis can lead to design innovation and optimization, and significantly reduce the cycle time for prototypes.
