Connectors & Sockets

Connectors and sockets are essential interface components that ensure reliable signal and power transmission in electronic circuits. A proper connector choice directly affects the mechanical durability and performance of your project. In this category, you will find a wide selection of connection solutions ranging from prototyping to industrial applications, including pin headers, DIP sockets, barrel jacks, USB connectors, terminal blocks, and many more.

Common Connector Types and Applications

• Pin Headers and Female Headers: Standard for development boards like Arduino, ESP32 and PCB-to-PCB connections, usually with a 2.54mm pitch.
• DIP and IC Sockets: Allow solderless replacement of integrated circuits; available in 8-40 pin counts.
• Power Connectors (Barrel Jacks): Used for DC adapter connections; outer diameter, inner diameter, and current rating compatibility are critical.
• USB Connectors: USB-A, USB-B, microUSB, and USB-C types provide data and charging interfaces.
• Terminal Blocks: Screw, pluggable, or spring-type options offer secure wire termination, commonly found in control panels.
• D-Sub, RCA and Jack Connectors: Employed in audio, video, and serial communication applications.

Key Selection Considerations

To choose the right product, evaluate the number of pins (how many contacts), contact pitch (e.g., 2.54mm, 1.27mm), current/durability rating, mounting style (DIP, SMD, wire-to-board), and plating material (gold, tin). Selecting an incorrect pitch leads to board incompatibility, while undersized current capacity can cause overheating and failure. Also pay attention to the thermal resistance of the legs during soldering and their mechanical strength to prevent breakage under stress.
