Screw Terminal Block: 4-Pin, 0.1″ Pitch, Side Entry (2-Pack)

These side-entry screw terminal blocks have a pitch of 0.1″ (2.54 mm), and can be used as alternatives to standard 0.1″ male or female headers on many PCBs and prototyping boards. Each block has four terminals for the stripped ends of 26 – 18 AWG wires. They are rated for 150 V, 6 A and ship in packs of two .

Overview

These side-entry terminal blocks have terminals that hold and release wires through the simple adjustment of a small screw, allowing you to easily make temporary connections to a PCB. Since each terminal has a single corresponding pin spaced every 0.1″ (2.54 mm), these terminal blocks can be used with prototyping boards and PCB holes intended for standard 0.1″ male and female headers (if there is sufficient clearance from nearby components).

Nine sizes are available, from 2 terminals through 10 terminals.

Note: These terminal blocks do not slide together like our stackable screw terminal blocks , and they do not fit next to each other on a 0.1″ grid, so you will need to get the exact size required for application. Additionally, they do not work well in solderless breadboards (their pins are too short).

Other terminal block options

We carry several different sizes and styles of terminal blocks in addition to these 0.1″ screw terminal blocks; the picture below shows a side-by-side comparison:
