This is not a part number. The marking "94V-0" (or 94V0) refers to the UL 94 Flammability Standard. It is a safety rating for the plastic material used in the component's casing or the printed circuit board (PCB) itself.
If the component is a black, square plastic box (about the size of a sugar cube) with 4 or 5 pins, it is likely a Relay.
The code SH1 identifies a robust Hall Effect sensor, while 94V0 assures you the PCB material is flame-retardant. When combined, you are looking for a safety-certified magnetic switch. sh1 94v0 datasheet free
Your fastest route to the free datasheet is to visit LCSC.com or Octopart, search for "SH1 Hall sensor," and download the manufacturer's PDF. Once you have the document, verify the supply voltage (4.5V to 24V typical) and the pinout (SOT-23) to integrate it into your project.
With this guide, you no longer have to guess. Go get your free datasheet and build with confidence. This is not a part number
Do not pay for datasheets. Reliable, free sources exist. Here is your verified list:
Since "SH1 94V0" is printed on the board itself, you likely need one of two things: Do not pay for datasheets
Scenario A: You want to know the PCB material properties.
Scenario B: You are looking for a component on the board.
A: No. It is rare to print "94V-0" on tiny SOD-123FL diodes. The marking is usually just "S1" or "SH1." The V-0 rating is a material property, not a body marking. Trust the datasheet and your supply chain.
A: Not legally, if you are selling the product in the US, EU, or Japan. Failure to use 94V-0 rated parts will cause your product to fail UL, CE, or PSE safety certification.
