JST B7B-XH-A XH Series 7-Pin Vertical SMT/THT Connector Header (2.50mm Pitch, Top Entry)

Establish reliable high-density power and signal wire-to-board connections with the genuine JST B7B-XH-A (often referenced as S7B-XH-A series) top-entry vertical header. As part of JST’s industry-standard 2.50mm pitch XH series, this 7-pin shrouded connector is designed for secure board mounting with integrated friction-lock polarization to prevent loose connections or accidental reverse insertion.

Its straight 180-degree (top-entry) orientation routes cables perpendicular to the printed circuit board, making it ideal for open-chassis designs, power distribution boards, lithium battery management systems (BMS), stepper motor harnesses, 3D printers, and custom DIY electronics.

Key Features:

• Standard 2.50mm Pitch: Perfectly compatible with all standard JST XH female crimp housings and pre-crimped wire assemblies.

• Top-Entry (Vertical) Orientation: Direct 180° wire entry allows easy top-down cable plugging and efficient board layout.

• Polarized Friction Lock: Keyed shrouded housing prevents reverse-polarity insertion and holds the mating plug securely.

• High Current Capacity: Supports up to 3A AC/DC continuous current per pin.
