What should be included in the first RFQ email?

Include sensor type, drawing or available magnet space, material and coating target, magnetization direction, working environment, quantity plan, and destination.

How quickly can we get an actionable response?

Complete RFQs receive practical engineering feedback, quotation direction, and clarification questions after review by the factory team.

Can we discuss custom OEM requirements before PO?

Yes. We encourage pre-PO engineering clarification to reduce prototype and mass-production risk.

RFQ Checklist Before You Send

Required Item	Example	Why It Helps
Sensor and application	Hall sensor, reed switch, encoder, proximity, or level sensor	Quickly narrows magnet type, geometry, and magnetic output assumptions.
Drawing and magnet envelope	Diameter, length, tolerance, housing space, air gap	Prevents quotation based on a magnet that cannot fit or switch reliably.
Material and coating	NdFeB / SmCo / ferrite, nickel / epoxy / custom finish	Aligns magnetic output, corrosion resistance, and working temperature.
Quantity plan	Prototype qty + annual forecast	Improves production planning and quotation accuracy.
Destination and terms	Country, Incoterm, requested ship date	Aligns packaging, documents, and shipping plan early.

RFQ clarity

Attach enough magnet context for an actionable first reply

A useful inquiry should connect the image-level product family with the drawing, sensor type, air gap, material, coating, magnetization direction, quantity plan, and destination. That lets the factory reply with engineering direction instead of only asking basic clarification questions.

What Happens After Inquiry

Engineering pre-check for magnet fit, signal assumptions, and data completeness.
Quote direction with material, coating, lead-time assumptions, and risk notes.
Sample scope alignment and validation acceptance criteria.
Production and delivery planning for approved programs.

Common Clarification Questions

Can I send a rough requirement before final drawings are ready?

Yes. Send your current assumptions first, then mark pending items clearly so we can return a provisional quote scope.

How should we handle engineering changes after sample approval?

Use a revision-controlled change request with effective lot and impact scope agreed by both teams.

Can we align on compliance files before mass production?

Yes. Please list required document types in the RFQ stage so they are included in validation and delivery planning.

Suggested First RFQ Email Format

If your team needs a fast start, use this structure in the first email. It improves quote precision and reduces clarification cycles.

Project background and application scenario.
Magnet target: shape, dimensions, material, coating, magnetization direction, and tolerance.
Sensing context: sensor model, air gap, movement path, temperature, and environment.
Commercial scope: prototype quantity, annual forecast, destination, and target ship date.

What You Should Review Before Sending RFQ

Products for architecture-level selection and magnet-family fit.
Solutions / Applications for scenario-specific constraints and validation priorities.
OEM Capabilities for design collaboration, quality controls, and delivery process.
Engineering Blog for practical checklists you can copy into buyer workflows.
Diametric Magnet Guide when your inquiry includes rotary angle sensing, diametric axis marking, or magnetic orientation constraints.

Typical First Response Package

Output	Purpose	Buyer Action
Magnet and assembly direction	Narrow viable options against sensor, air gap, material, coating, and assembly assumptions.	Confirm baseline magnet path before cost-detail discussion.
RFQ clarification list	Close data gaps that affect quotation and lead-time accuracy.	Return missing values and drawing references in one reply.
Validation recommendation	Define sample test scope and acceptance evidence for technical sign-off.	Align internal engineering and procurement gates before PO.
