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 two terminals for the stripped ends of 26 – 18 AWG wires. They are rated for 150 V, 6 A and ship in packs of four.
This extra-tall stackable 40-pin female header features two rows of 20 pins spaced with a 0.1″ (2.54 mm) pitch. It includes three 0.1″-thick spacers for additional clearance, and the extended pins allow multiple units to be stacked as popularized on Arduino shields.
