XH2.54 Wire To Board Plug Connector

The XH2.54 (2.54 mm pitch) wire-to-board plug connector provides a compact, reliable cable-to-PCB interface for low-voltage electronics. The plug features a shrouded, polarized keying to prevent mis-mating; optional friction lock/self-lock mechanisms improve retention under vibration or maintenance. It mates with vertical or right-angle headers (THT as standard, SMT optional) to form a complete end-to-end connection.

Key features

• 2.54 mm pitch with shrouded, polarized housing for clear alignment and smooth mating
• Optional friction lock/self-lock to enhance vibration and pull-out resistance
• Compatible header orientations: vertical (top-entry) and right-angle (side-entry); THT standard, SMT optional
• Complete BOM: housing, crimp terminals, headers; wire harness customization available
• Drawings, 3D models, PCB footprints, and assembly guidance provided

Typical specifications (vary by supplier/series)

• Circuits: 2–13 pins
