Oil Pressure Sensors & Switches
The reading that stops an engine before it seizes
Oil Pressure Sensors & Switches
Switch or sender, fixed or variable, for every engine family we cross — with the thread, taper and warning threshold the OE part uses.
Oil pressure is the one signal a driver will act on immediately, which makes the sensor's failure mode as important as its accuracy: a sender that reads high is worse than one that reads nothing.
We supply discrete switches with fixed or adjustable set points and analog senders with linear output, matched to the thread, taper and warning threshold of the OE part being replaced.
Every unit is pressure-cycled on our bench and ships with its actual switch-point record, not just the nominal one.
Representative series and where they fit
Representative series, not an exhaustive price list. Series codes are our internal naming; the connector and range cells are what a buyer actually checks first. For any OE number you fit we will return the exact SHR equivalent with its own datasheet.
| Series | Sensing element | Range | Connector | Typical fitment |
|---|---|---|---|---|
| OPS-1xx | Diaphragm switch | Fixed set point 0.3 – 1.8 bar | M10 × 1 / spade | Passenger car engines |
| OPS-2xx | Diaphragm switch | Adjustable 0.5 – 4 bar | M14 × 1.5 / spade | Commercial vehicles |
| OPS-3xx | Linear sender | 0 – 10 bar ratiometric | 1/8-27 NPT / 3-pin | Truck, marine, gensets |
OE numbers in demand
Numbers harvested from current after-market demand in our categories, with the application the demand carried. This is a statement of what we cross-reference routinely — not a fitment guarantee. Send your OE number and we will confirm coverage and return the datasheet before any order is placed.

Why distributors buy from SHR
Switch or sender from one family
Discrete warning switches with fixed or adjustable set points and linear senders share the same diaphragm and thread options.
Thread and taper per the OE part
M10, M14 and 1/8-27 NPT with the correct seat — a cross-threaded taper is the most common fitting failure in this category.
Actual switch point shipped with each unit
Pressure-cycled on our bench and shipped with its measured switch point, not just the nominal figure.
Failure mode designed for the driver
A sender that reads high stops an engine that is fine; we test the failure direction, not only the accuracy.
12 V and 24 V vehicle systems
Covering passenger car and commercial vehicle electrics from the same family.
