DC Coax/Barrel Jack 2.1 x 5.5mm Panel Mount with Protective Cap

This panel-mount DC coax barrel jack offers a robust and dependable power entry solution for a wide range of electronic enclosures and equipment. Designed to accept the ubiquitous 2.1 x 5.5mm centre-positive plug, it provides a standardised interface for powering devices from external adaptors or regulated supplies. The inclusion of a protective cap is a thoughtful addition, effectively shielding the socket from dust, debris, and accidental short circuits when not in use, thereby prolonging the connector's lifespan and maintaining reliable contact integrity.

Ideal for use in audio equipment, test instruments, small amplifiers, or DIY projects, this socket allows for a clean, professional panel installation. It is particularly well-suited for applications where the power connection may be frequently disconnected or where the equipment is used in less-than-pristine environments, such as workshops or on stage. The cap ensures the socket remains clean and ready for use, preventing common issues caused by contamination.

Technically, the socket features a standard 2.1mm centre pin and a 5.5mm outer barrel diameter, rated for 2.5A at 24V DC. The panel-mount design incorporates a threaded barrel and nut for secure fixing to panels up to a typical thickness, providing a stable and vibration-resistant connection. The robust construction ensures consistent electrical performance and long-term durability, making it a reliable choice for both prototyping and permanent installations. This component is an essential, practical addition to any power supply or device requiring a clean, protected DC input.
