Terminal Blocks

About

Terminal Blocks are used to provide a secure and reliable semi-permanent wire connection to PCBs and modules. The blocks are usually soldered to a PCB with strong through-hole connections. We stock a range of terminal blocks in different pin arrangements to cater for most projects and PCB designs, with the most common using 2.54mm/0.1" pin spacing. Wiring to a terminal block is easy - simply loosen the screw or clamp mechanism, pop your wire in (using ferrules ideally, or a tinned wire), then tighten the screw/mechanism back up. Always test the connection - you should be able to give the wire a decent tug without it budging! We also stock a range of terminal block adapter modules, which you can find over in our Breakouts & Modules section .
