Screw terminal blocks are the clean, maintainable solution for PCB-to-wire connections — no solder, no loose ends, easy to swap out later. These 3.5mm pitch 2-pin blocks are a practical size: wide enough for a range of wire gauges, compact enough not to dominate your board, and designed to snap together to build up any terminal count you need.
Key Features
- Pitch – 3.5mm
- Pins – 2-pin per block
- Snap-Together – Link multiple 2-pin and 3-pin blocks side-by-side for custom lengths
- Screw Adjustment – Standard flathead screwdriver, easy to tighten and release
- PCB Mountable – Fits most perf/proto-board (mount diagonally for 2.54mm grid boards)
- Pack of 5 – 5× 2-pin blocks per order
Note: These are 3.5mm pitch — they do not fit 2.5mm spaced PCB holes and do not fit into solderless breadboards.
Ideal For
- PCB-to-wire connections on custom and proto boards
- Power input terminals, sensor connections, and signal wiring
- Any project where re-wiring or maintenance is anticipated
Jargon buster
Plain-language definitions for the technical terms used above.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- screw terminal
- A connector that clamps bare wire using a small screw, making it easier to attach and remove wires without soldering. Screw terminals are useful for power wiring or thicker wires that are not suited to small plug-in connectors.
