Shielded DC Power Jacks

Shielded DC Power Jacks 12v are equipped with a brass shell for RF / EMI shielding and are designed for harsh environments. These Switchcraft shielded jacks feature a front-mount jack with a metal housing and a thru-hole PCB mount jack with a metal shield. Both types are available in multiple center-pin sizes. The jacks operate over a -40°C to +65°C temperature range and feature 5000 cycles minimum durability.

Shielded DC Power Jack connectors are a special type of DC power connector designed to protect the internal circuitry of your electronic device from electromagnetic interference (EMI) and radio frequency interference (RFI). These interferences can cause noise, signal degradation, and even malfunctions in sensitive electronics.

A shielded DC Power Connector is a type of barrel-style DC connector that includes metal shielding around the body of the jack to provide electromagnetic interference (EMI) protection, enhanced durability, and better grounding performance. These jacks are commonly used in sensitive or high-reliability electronic applications where reducing electrical noise and ensuring signal integrity are important.

A shielded DC power socket /jack is a smart upgrade from standard barrel connectors when your design requires clean power, robust construction, and electrical noise protection. It’s ideal for mission-critical or noise-sensitive applications, especially in environments with lots of other electronics or wireless signals.
