The NOx Sensor Family: 109 Entries by OE Number
One family, 109 entries
The NOx sensor family is the largest single family in this catalogue: 109 entries, each filed under its own OE number. The deep-checked entries carry full records, cross-reference lists among them; the remaining entries are listed by number in the family listing. The deep-checked entries carry Scania, Volvo, Iveco, Cummins and Mercedes-Benz applications. Every entry in the family is confirmed the same way: the number from your old sensor is read against the entry that carries it, and the reply names that entry — its title, article number and application as listed — before any price is set. Nothing in this article goes beyond what the entries themselves record: where an entry prints a full specification block it is walked row by row below, and where an entry records only a title, an article number and an application, that is what is reported.
The flagship entry, field by field
The family's flagship entry is the Scania sensor 5WK96612E, article number OE212472. Its OEM number list reads 1782596, 1872080, 1908536, 2020691, 2247379 and 2296799 — six cross-references carried on one entry. The specification block lists a supply voltage of 24V, a NOx measurement range of 0–500 ppm or 0–1500 ppm, and lambda figures printed as Lin. λ 0,75 to air and Bin. λ >0,75V at λ=0,9 and <0,2V at λ=1,1. It removes most of the free oxygen from the gas it samples. The application line reads Scania P-, G-, R- and T-Series trucks, plus Bus 4-, F-, K- and N-Series. The entry also prints a warranty line, and its packaging unit as one piece. Those rows are the whole of what the entry states, and they are what a confirmation for this number is made from.
Rows that differ across the family
The flagship's rows are not the family's rows. The entry for 5WK97373 lists a supply of 12V / 24V where the flagship lists 24V, with the same printed NOx range and lambda block; its title names Volvo while its applicable-models line reads ‘for BENZ’, and both are reported here as the entry prints them, because the entry is the authority and the two lines are what a buyer holding that number needs quoted back. The Mercedes-Benz entry A0091539328 / 001 (article OE211965) lists 24V, a packaging unit of one piece and a packaging-unit weight of 0.310 kg. Voltage, weight and application are entry-level facts: they are confirmed with the entry your number lands on, never assumed from the family title.
The other deep-checked entries
Seven NOx entries are deep-checked in the catalogue's records. Beyond the three walked above, they are the Iveco sensor 5WK96733B (article OE211771) and three Cummins references — 5WK96751C (article OE212148), 5WK96740 (article OE211906) and 5WK96741B (article OE212211) — which are walked on the Cummins article of this blog. For each of these the record holds the title, the article number and the application as listed; construction and calibration detail are not recorded, and are not filled in here. The remaining entries of the 109 are listed by number in the family listing, and a number not printed on any page is checked against the full family when it is sent.
The Mercedes-Benz entry in full
The Mercedes-Benz entry A0091539328 / 001, article OE211965, records a supply voltage of 24V, the printed NOx range of 0–500 ppm or 0–1500 ppm, and lambda figures printed as Lin. λ 0,75 to air and Bin. λ >0,75V at λ=0,9 and <0,2V at λ=1,1. Its packaging unit is one piece at a packaging-unit weight of 0.310 kg, and its application is carried by its title and listing rather than by a series list. It stands in this article as the family's reminder that entry depth varies: which rows an entry carries is read from that entry, and the reply states the rows the entry carries and the rows it does not. A buyer comparing two Mercedes-Benz numbers is comparing entries, not titles.
A worked inquiry
A complete NOx inquiry is short. It names the vehicle and the engine, gives the OE number from the old sensor's module or label, adds the position wording from the fault text where the fault text names one, and states the quantity and the packaging option. Sent that way, the number is read against the family's 109 entries, the entry it lands on is named in the reply with the rows that entry carries — voltage, range and application where printed — and the quotation is made for that entry. A number that lands on a title-only entry is confirmed on the fields that entry does record, and the reply says which fields those are.
What to send with a NOx inquiry
The inquiry should carry the OE number from the old sensor, the vehicle model and the engine, and the position wording from your fault text where it names one. The discipline is the family's: identify the position, read the OE number from the old unit, and match it against the entry that carries it. The company states that more than 100 catalogued items can be dispatched within 3 days and more than 2,700 within 15 days. The company's FAQ states that a single-piece NOx sample order is accepted when the item is in stock. Four packaging options are offered across the family — OEMEMBER branded, UAP branded, blue neutral and white neutral boxes. Warranty terms for an order are confirmed in the quotation before payment, and product certificates are available upon request.
Reading a cross-reference list
A cross-reference list is read as a set of doors into one entry. A workshop holding any one of the flagship's six OEM numbers — 1782596, 1872080, 1908536, 2020691, 2247379 or 2296799 — is holding a reference to the same catalogue entry, and the search starts from whichever number is stamped on the old sensor or printed in the parts system. The same reading applies across the family: the entry a number lands on carries that number's application and, where printed, its specification block. A number that appears in no printed list is not outside the family; it is checked against the family's 109 entries when it is sent, and the reply names the entry it belongs to.
Key takeaways
The NOx family holds 109 entries, each confirmed by its OE number against its own entry. The flagship entry 5WK96612E (Art. OE212472) lists six OEM cross-references, a 24V supply, a NOx range of 0–500 ppm or 0–1500 ppm, Scania P-/G-/R-/T-Series and bus applications, and its warranty line as printed. Rows differ across the family — the 5WK97373 entry lists 12V / 24V — so the entry, not the title, is quoted back in a confirmation. Send the OE number, the vehicle and engine, and the position wording from your fault text where it names one.
