Registered Jacks

Registered Jacks

Registered jacks provide a reliable mechanical and electrical interface for wired communication in embedded and automation projects. RJ45 sockets, often paired with built‑in magnetics and status LEDs, support standard Ethernet cabling such as Cat5, Cat5e and Cat6, making them ideal for network‑connected controllers, robotics platforms and IoT devices. RJ11 connectors offer a compact solution for telephone‑line signalling or low‑pin count serial links. Most of these jacks are supplied as through‑hole parts with PCB mounting posts, allowing straightforward soldering and easy integration into prototype boards or custom PCBs. Breakout boards expose each pin on a 0.1 in grid, simplifying connection to breadboards and wiring harnesses. Key attributes include mechanical robustness, compatibility with common cable types, built‑in shielding for noise reduction and clear visual feedback through LEDs, all of which contribute to dependable performance in a range of wired projects.
