Oil Pressure Sensors and Switches: Two Catalogue Families

Topic: oil sensor · From the TruckSensorFactory editorial desk

Two families, told apart by entry

Oil pressure devices appear in two places in this catalogue: the dedicated oil pressure family of 8 entries, and switch-type devices carried within the 31-entry pressure root family. The two are separate catalogue items, filed under separate entries, and an order states the OE number of the device that came off the engine: the entry that number lands on is the type the confirmation is made for. The deep-checked entries of both families are walked below, field by field, exactly as their records print them.

OE211202, field by field

The Scania entry referenced OE211202 sits in the oil pressure sensor family. Its replaces list reads 1457306, 1471744, 1535521, 1862817 and 1862892. Its warranty line is printed in the source record as one of the entry's own fields. Those fields — the reference, the replaces list, the warranty line — are what the entry states, and a confirmation for this number is made from them, together with the vehicle and engine named in the inquiry.

OE212083, field by field

The Mercedes-Benz entry referenced OE212083 records an operating pressure to a maximum of 20 bar and a thread of M10 x 1, with its warranty line as printed. It is one of the few entries in these families that prints a pressure figure and a thread together, and both figures belong to this entry alone: they are not carried across to any other entry in either family, and a quote for another number is confirmed against that number's own record.

OE211777: read the entry, not the title

The entry referenced OE211777 carries the title ‘Oil Pressure Switch Sensor for Volvo 20886108’, while its applicable-models line reads DAF and its reference numbers are 1673078, 1737643 and 1470270256. Its packaging is listed as one piece in a bag, and it carries a warranty line as printed. Its record states no contact, threshold or output form, so nothing in the entry itself establishes whether the device is a sensor or a switch: the type is settled from the old part at inquiry rather than assumed from the title. This entry is the family's standing lesson — the entry's data decides, not its heading, and not the vehicle named in it.

Titles that mix the two words

Several titles in these families mix the words sensor and switch in one line — OE211777's title is the deep-checked example. A mixed title is not a third device type and not a contradiction to resolve by guesswork: it is a title, and the entry behind it records what it records. Where the record settles the type, the confirmation follows the record; where it does not, the type is settled from the old part at inquiry. Buyers quoting a number from a mixed title should expect the reply to quote the entry's fields back exactly for this reason.

The root family around the switch entries

The pressure root family's 31 entries are the wider shelf these switch records sit on. Most are listed by title, brand and application; the two deep-checked records walked in this article — 20428459 with its switch point and thread, 20382500 without printed specification fields — show the range of depth a buyer will meet. The family's discipline is the oil family's discipline: the number first, the entry's own data second, and no field borrowed from a neighbouring entry to fill a gap in the record being quoted.

Warranties, as printed

Warranty lines in these families are entry-level facts like any other field. Each of the three entries walked in this article prints its own warranty line in its source record. The lines are entry-level facts, reported here as the records carry them; the warranty applying to an order is the one confirmed in the quotation for the confirmed entry, and an order's own terms are settled in its quotation before payment, as the ordering pages of this site state.

A worked inquiry

A complete oil pressure inquiry names the vehicle and the engine, gives the OE number from the device removed, and states which port it came from where two devices are fitted. Where a gauge reading was taken, the reading is included as recorded. The reply names the entry the number lands on — in the oil family or the root family — quotes the fields that entry carries, and states where a field the order turns on is not recorded, so it can be confirmed against the old part. Nothing in the reply is filled in from the family title.

The root family's switch-point entry, and the gauge record

Within the pressure root family, the Volvo entry referenced 20428459 (article OE211113) records a switch point from 0 to 15 bar and a thread of M16 x 1.5 — the root family's deep-checked switch-type record. When an inquiry follows a low-pressure warning, one record is worth sending with the OE number: a mechanical gauge reading taken at the gallery, recorded alongside the instrument's reading, the two compared as recorded — the engine's oil supply is judged from the gauge reading and the engine's own state, not excluded by this comparison alone. The catalogue entries behind both families are listed by vehicle and engine application; send the number, the vehicle and the engine, and the reply confirms the entry it lands on.

One more root-family record

The root family's second deep-checked record is the entry referenced 20382500, carried under article OE211169. Unlike the 20428459 entry walked in this article, its record prints no specification fields beyond its title, brand and application as listed. The pair of entries shows the family's range in miniature: one entry printing a switch point and a thread, the next printing neither. Both are confirmed the same way — by their numbers, against their own records — and a field that matters to an order and is not printed is asked for with the OE number rather than assumed from a neighbouring entry.

Key takeaways

Oil pressure devices are filed in two places: the 8-entry oil pressure family and the 31-entry pressure root family. OE211202 (Scania) and OE212083 (Mercedes-Benz, to max. 20 bar, M10 x 1) are sensor-family entries; the root family's 20428459 records a switch point from 0 to 15 bar. The OE211777 entry records no contact, threshold or output form, so its type is settled from the old part at inquiry. Send the OE number, the vehicle and the engine.
