Pot magnet is a term buyers search for often, and it usually means a magnet fitted into a pot or housing, most closely matching the countersunk / counterbore pot category name on this site. This guide explains what pot means in that category sense, why this site publishes no pot magnet detail page, and what a buyer should send instead of a one-word pot request. The short answer is that pot is a starting point for an inquiry with dimensions, not a specification that can be ordered by name alone.
What pot means as a category
A pot magnet, in general usage, is a magnet mounted in a steel pot or housing, often with a hole or thread for fixing, so that the magnetic effect is concentrated on one face and the part can be screwed or bolted into place. That general description is useful orientation, but it is not a specification for any particular pot magnet, because pots vary in diameter, height, hole type, thread and housing material, and none of those variations is published as a verified range on this site. The company's navigation lists countersunk / counterbore pot magnets as one of eight assembly categories, and that listing is the extent of the pot evidence here: a name, not a table.
Two consequences follow. First, there is no pot magnet detail page on this site, and no pull-force figure, base-material figure or coating figure is published for pot magnets, because none was verified assembly by assembly. A guide that quoted a pull force for pot magnets in general would be inventing a figure for a category that spans many sizes. Second, a buyer who writes only pot magnet in an inquiry will necessarily be asked for dimensions, because the word alone does not distinguish a small pot from a large one, a countersunk pot from a counterbore pot, or a threaded fixing from a plain hole.
Countersunk, counterbore and threaded: three fixings, three questions
The assembly category name itself contains three fixing ideas: countersunk, counterbore and pot. A countersunk fixing uses a recessed hole that lets a screw head sit flush; a counterbore uses a flat-bottomed recess; a threaded fixing uses a thread rather than a through hole. Each implies different mating dimensions, and an inquiry should say which fixing is meant, with the screw or bolt size where it is known. The countersunk shape detail page publishes a hole range of M1–M10 for countersunk shape magnets, but that range belongs to the countersunk shape family, not to pot assemblies, and it must not be transferred to a pot inquiry as if it were a pot specification.
Threaded magnets appear separately in the assembly list as threaded magnets, and they too carry no published thread table on this site. A threaded inquiry should state the thread size and the housing dimensions explicitly, and ask whether the combination can be made, rather than assuming a standard thread from the category name. The same rule covers mounting, hook, channel, rubber coated, adhesive and PVC waterproof categories: names guide the inquiry, dimensions complete it.
What to send instead of a one-word pot request
Send the overall diameter and height of the pot assembly, the fixing type — countersunk, counterbore, threaded or plain hole — with its size, the magnet shape inside if known, the grade temperature series under discussion, and the operating temperature and environment. State whether the magnetic face must work in contact or across a gap, and describe the mating part the pot will fix into, because a pot inquiry without mating dimensions will need a second round of questions. Please confirm minimum order quantity and lead time before ordering. Coating is an open question: please confirm coating requirements before ordering, and do not assume a coating from the category name.
If the requirement is actually a plain countersunk magnet rather than a pot assembly, the countersunk detail page is the right specification source: round and rectangular forms customized, hole M1–M10, standard tolerance ±0.05 mm and minimum ±0.01 mm, directions axial and through thickness. Naming the right category at the start — shape or assembly — is the single most useful thing a pot inquiry can do, because it determines which page the specification is checked against.
Why this guide refuses to quote a pull force
Pull force is the figure pot buyers ask for most, and it is the figure this site most deliberately does not quote for assemblies. Pull force depends on the magnet size, the housing, the mating surface, the gap and the temperature, and a single number quoted without those conditions would mislead more than it helped. A buyer who needs a holding force should state it as a requirement — the force required, at a stated gap and temperature, against a stated mating surface — and let the review confirm whether a described assembly can meet it. That framing turns an unanswerable one-word request into a checkable engineering question, which is the purpose of this guide.
Questions to send with a pot magnet inquiry
A specification that can be answered names four items together: the shape family, dimensions inside that family's published range, the grade temperature series, and the magnetization direction exactly as listed for that shape. Add the operating temperature and the fixing method where they affect the choice, and ask coating and warranty as open questions. Please confirm minimum order quantity and lead time before ordering. Warranty terms are unavailable on the published pages — please confirm warranty terms before ordering. Certificates are available upon request; no certificate number or issuing body is published here.
An inquiry that names only a grade, or only a size, will be answered with questions rather than a confirmation, because neither item alone is a complete specification. The extra sentence that states the direction in plain words, or that gives the mating dimension for a fixing, is often the sentence that prevents a second round of correspondence, and it costs nothing to include at the start.
Frequently asked questions
Which grade series should I discuss for neodymium pot magnet guide?
Discuss the grade series against the shared grade maximum working temperature table, using the temperature the magnet will actually see in service, including heat from neighbouring parts. The series run from N35–N52 at 80°C through the M series at 100°C, the H series at 120°C, the SH series at 150°C and the UH series at 180°C to the EH series at 200°C. State the operating temperature as a figure in the inquiry, because a grade name without its temperature row has not been specified for a warm environment, and the review needs the temperature to confirm the series discussion rather than infer it from a name alone.
How exactly should I state the magnetization direction?
Copy the direction exactly as listed for the shape named in the inquiry, and do not substitute a synonym that feels equivalent, because the same word can describe a different arrangement on a different shape. Where a drawing uses a different convention, add a plain-words description of the pole positions alongside the listed term, so the review can reconcile the two without guessing. A direction that is assumed rather than confirmed is a common source of a magnet that is dimensionally correct and magnetically wrong for its fixing, so the extra sentence describing the poles is worth writing even in a short inquiry.
What should I ask about coating, warranty and certificates?
Please confirm coating requirements before ordering, because coating type names were not transcribed from the company illustration and no coating type is named on this site; state the operating environment with the coating question so the answer can be specific. Warranty terms are unavailable on the published pages, so please confirm warranty terms before ordering rather than assuming a term. Certificates are available upon request: name the certificate required and its purpose in the inquiry, because no certificate number, issuing body, scope or validity period is published here, and a named request can be matched to the order it belongs to.
What if my size or combination is not in the published range?
Ask whether it can be made, and send the dimension as written rather than rounding it into the published range. A value outside a shape range, a direction not listed for that shape, or a combination of features from two shapes should be raised as an explicit question, with a dimensioned sketch where the geometry is curved, holed or otherwise not captured by a single size figure. Please confirm minimum order quantity and lead time before ordering. A question asked before ordering costs one message; a forced fit into the nearest published table can cost the whole part, because a magnet that matches its order and fails its fixing is worse than an extra round of questions.
