2.54mm Terminal Block - 4-pin

This 2.54mm 4-pin terminal block makes it easy to connect four wires securely to a PCB or perfboard. With a reliable cage clamp design, it's ideal for prototyping, tidy builds, and quick adjustments.

These compact 2.54mm (0.1") terminal blocks are a handy solution for making wire-to-PCB connections more secure and manageable. Ideal for prototyping and perfboard work, they offer a neat and reliable alternative to loose wiring, especially when working with multiple connections. Each terminal block is spaced at a standard 2.54mm pitch, making them compatible with most perfboards and through-hole PCBs. We found they work just fine in breadboards - just make sure you push them in firmly, or the connection can be a bit so-so. They have the nicer 'cage' style clamp rather than the less-reliable 'screw crushing the wire' type, which everyone here prefers. They're easy to use with a small precision screwdriver, handle a range of wire gauges, and don’t take up much space on your board — great for keeping things tidy and easy to maintain. Oh - and they fit our USB-A Horizontal Breakout just dandy! Specifications
