Magnetic Sensors
Magnetic sensors detect the presence, strength, and direction of magnetic fields for position sensing, current measurement, speed detection, and proximity switching. This category includes Hall-effect sensors, magnetoresistive (GMR/TMR/AMR) sensors, and magnetic encoders from Allegro, TDK Micronas, Honeywell, Infineon, and ams-OSRAM.

How to Choose Magnetic Sensors
A practical selection framework for Magnetic Sensors covering specifications, packaging, lifecycle, and sourcing on Octatronics.
Define electrical and environmental requirements
Start with the required function and operating conditions for Magnetic Sensors, then lock in critical parameters such as measurement range, accuracy, interface, supply voltage, and response time. Match these against datasheet limits, not catalog summaries alone.
Validate package and land pattern compatibility
Confirm the Magnetic Sensors package matches your PCB footprint, pick-and-place constraints, and moisture sensitivity handling. Verify reel/tape or tube packaging for production.
Check lifecycle, compliance, and alternates
Review lifecycle status (Active, NRND, EOL), RoHS, and approved alternate sources for Magnetic Sensors before committing to high-volume builds. Use Octatronics cross-reference data when a drop-in replacement is needed.
Compare manufacturers and request pricing
Filter Magnetic Sensors by manufacturers such as ROHM and Infineon Technologies, compare key specs side by side, then submit an RFQ with quantity, target delivery, and traceability requirements.
