Below is a summary of the pin details for the JST B2B PH K 01x02 Connector as used for the + PMID - entry. Note that as a passive through‐hole shrouded header the connector does not include active circuitry; its pins are simply the physical terminals for signal or power continuity. The datasheet (from the JST document) provides mechanical and electrical ratings rather than functional assignments. In many designs the assignment is made in the schematic, so the functions below represent typical usage:
Table
| Pin | Function | Electrical Characteristics | Special Considerations |
|---|---|---|---|
| Pin 1 | Typically assigned as the positive side (or the “active” terminal) in your design. This terminal is used for supplying power or carrying a positive signal. | Rated for up to 2A (AC/DC) with a voltage limit of 100V AC/DC. It is designed to operate within a temperature range of -25°C to +85°C. Contact resistance and insulation resistance meet the datasheet guidelines. | Ensure that the PCB footprint (pad dimensions and solder hole sizes) meets the recommendations in the datasheet. Proper soldering is critical to maintain reliable contact, especially since dimensions may vary with PCB material and method of hole plating. |
| Pin 2 | Typically assigned as the negative or return side. It serves as the counterpart to Pin 1—completing the circuit by providing a return or ground path as defined in your design. | Shares the same ratings as Pin 1: up to 2A at 100V AC/DC and operating in the -25°C to +85°C range with similar low contact resistance. | Verify that the pad layout and soldering parameters (including hole size and placement) conform to the datasheet’s mechanical guidelines. Uniform solder quality and alignment are important for optimal performance. |
Note:
– Exact assignment (positive/negative) should follow your schematic’s labeling.
– Always refer to the manufacturer's datasheet for detailed mechanical dimensions (e.g., hole diameter, pad size, and spacing) and any additional recommendations provided by JST.
– As this connector is passive, its “input/output” traits are defined solely by its electrical ratings and mechanical robustness.
