Industrial Automation
Pneumatic cylinder sensing, conveyor speed feedback, proximity switching — magnets paired with Hall and reed sensors for harsh environments.
What Buyers Need to Confirm Before Sampling
Risk Checks Before Price Comparison
The same-size magnet can fail if field direction, air gap, coating, or packing assumptions are wrong.
Will It Trigger the Sensor?
Review sensor type, sensitive axis, air gap, motion path, and target field before selecting shape or grade.
Will the Material Survive?
Choose material and coating around temperature, humidity, liquid exposure, adhesive use, corrosion risk, and demagnetization margin.
How Will the Lot Be Accepted?
Define dimensions, polarity, field measurement point, pole map, visual limits, packaging checks, and records before sample approval.
What Changes Cost or Lead Time?
Separate magnetizing fixtures, tooling, coating, sorting, reports, oriented trays, assemblies, and export packing from the base part price.

Hall Effect Sensor Magnets
Best for OEM engineering teams selecting magnets around a fixed Hall IC, PCB position, and housing envelope.
- Sensor IC model or target operate/release point
- Air gap range, housing material, and available magnet envelope
- Drawing, tolerance, coating, and magnetization direction
Reed Switch Magnets
Best for switch manufacturers and equipment OEMs that need stable operate and release distance in production.
- Reed switch model or target operate/release distance
- Actuation path, mounting direction, and required switching repeatability
- Magnet envelope, drawing, tolerance, material, and coating
Multipole Ring Magnets
Best for OEMs that need a repeatable magnetic pole pattern matched to an angular sensor or speed pickup.
- Pole count, pole pattern, and phase/reference mark requirement
- Ring dimensions, tolerance, material, coating, and mounting method
- Sensor type, air gap, speed range, and signal target
Diametric Sensor Magnets
Best for engineers using the rotating field of a diametric magnet as the sensing reference.
- Drawing or target diameter, length, and tolerance
- Required diametric direction mark or assembly reference
- Sensor IC, air gap, rotation angle, and expected output behavior
Micro Sensor Magnets
Best for buyers whose design is limited by small space, assembly handling, and tolerance stack-up.
- Drawing with dimensions, tolerance, chamfer, and surface requirements
- Material, coating, magnetization direction, and polarity marking needs
- Assembly method, adhesive or carrier details, and handling constraints
Custom Magnetic Assemblies
Best for OEM buyers who want to reduce internal assembly risk by sourcing a magnet as a controlled subassembly.
- Assembly drawing, exploded view, or CAD package
- Magnet material, coating, magnetization, and polarity datum
- Carrier material, retention method, and assembly environment
