Product Description
The JST PH 2.0mm 3-Pin Male Connector Header (B3B-PH-S) is a miniature through-hole mounting connector designed for secure, polarized wire-to-board connections in compact electronic devices. Featuring a 2.0mm pitch spacing and a robust shrouded design, it ensures reliable mating with matching JST PH female cable assemblies while preventing reverse polarity insertion.
Essential for microcontroller peripheral wiring, sensors, telemetry modules, and custom electronic harnesses, this right-angle or straight header solders cleanly onto printed circuit boards for durable three-conductor electrical connections.
⚠️ Polarity & Pinout Tip: Always verify your circuit’s pin assignment (such as VCC, Signal, and Ground) against your mating cable before powering on your devices to prevent accidental short circuits or reverse-voltage damage.
Technical & Architectural Highlights
-
Standard 2.0mm Pitch: Compact pin spacing designed for high-density modern electronics and miniature circuit layouts.
