This catalog is built from supplier listings, which means every figure published here has been read off a page designed for a different audience. Four habits on those pages cause most of the errors, and knowing them is useful whether you are reading a listing directly or checking a quotation built from one.
1. The price cell is two numbers glued together
A cell reading ¥3399983 usually means ¥33 with 99,983 pieces in stock, not thirty-three thousand yuan. The same pattern produces ¥1000 and ¥999 rows that are not prices at all but placeholders — the row is labelled 'contact customer service' and the number is there to satisfy a required field. On one service-switch listing, six of nine rows carried a placeholder while the seventh carried the real price of ¥183.
The reliable source is not the visible cell but the SKU data embedded in the page, which separates price from stock. Anything published in this catalog was taken from that data, and rows that only carried a placeholder were published as quote-on-request instead of being given a price.
2. Sold-out sizes stay in the list
A variant that cannot be ordered still appears, often without a visible warning, and the stock figure is the only clue. Three families in this catalog have 4.0 and 6.0 mm² positions sitting at zero while 2.5 mm² is available. A buyer who reads a variant list as an availability list will plan a build around a contact that cannot ship.
3. Part of the spec list can be behind a login
Some pages show one or two variants and then 'log in to see all specifications'. That is not a paywall; it is a feature for registered trade accounts. It does mean a public reading of the page understates the range: one MNS switch shows a single 350 A option publicly while the supplier's full ladder runs to nine ratings in two mounting versions. Where the full list is not public, the catalog publishes only what is visible and says so.
4. Spec fields get filled with template values
The most misleading field is voltage. Three energy-storage listings print DC5–24 V in a rated-voltage column for connectors that take up to 107 mm² cable — a value inherited from a template, not a specification. One high-voltage connector listing leaves the field as 'contact customer service'. Neither is usable, and both are exactly the kind of number that ends up on a drawing and causes a problem two years later.
Treat any spec field that is same across obviously different products as suspect, and ask for the value in writing.
A reading routine
- Open the SKU data, not the price cells.
- Mark every row with zero stock before you plan anything.
- Cross-check the spec table against the title — a mismatch means one of them is stale.
- Ask for the missing fields in writing, in one message, with the part numbers listed.
