Connectors & interconnects
Board, wire and I/O connectors that join assemblies together — from pin headers to USB and FFC/FPC.
Connectors join boards, cables and enclosures: pin headers and sockets between boards, wire-to-board and wire-to-wire housings for harnesses, terminal blocks for field wiring, and USB, FFC/FPC and DC power connectors for I/O.
Connectors are rarely interchangeable across series. The mating half decides the match, so the series or part number of the existing connector — or a clear photo next to a scale — is the most useful thing to share.

What to include in an enquiry
The more of these details an enquiry has, the quicker a requirement can be reviewed. A full manufacturer part number or a BOM line covers most of them.
- Pin count
- Pitch
- Orientation
- Number of rows
- Mounting style
- Gender or mating type
- Pitch
- Centre-to-centre spacing of the contacts, for example 2.54 mm, 2.0 mm or 1.25 mm.
- Pin count and rows
- Number of positions, and single or dual row.
- Mounting and orientation
- Through-hole or surface-mount; vertical (straight) or right-angle.
- Gender and mating half
- Header or socket, plug or receptacle — and the part number of the connector it must mate with.
- Wire size and termination
- For wire connectors: wire gauge (AWG or mm²) and crimp, screw-clamp or spring-clamp contacts. For terminal blocks, also the current and voltage rating.
- Locking and polarisation
- Whether a latch, friction lock or keyed housing is needed to prevent mis-mating or loosening under vibration.
Matching a connector takes more than the pin count. Pitch, rows, orientation, mounting style and the mating half all need to agree — a part number or photo of the mating connector helps.
