Also known as barrel connectors, concentric barrel connectors or tip connectors, these small cylindrical connectors come in an enormous variety of sizes. Barrel plug connectors are commonly used to interface the secondary side of a power supply with the device. Some of these jacks contain a normally closed switch; the switch can disconnect ...
Small cylindrical connectors come in various sizes. They may be known as "coaxial power connectors," "barrel connectors," "concentric barrel connectors," or "tip connectors." These plugs are intended for use on the cable connected to an external AC adapter (power supply). The matching jack or socket is permanently fitted to power the equipment.
This is a unique-looking barrel connector, apparently intended for providing a DC output jack (most DC jacks are used for power input). Possibly available in multiple voltage ranges, the one for voltage classification 2 (3.15 to 6.3 V) has an outside diameter of 4.75 mm and a protruding pin of 2.5 mm diameter. Previously known as EIAJ RCX-5321.
The connector was formally adopted as part of PCI Express 5. [1] The connector was replaced by a minor revision called 12V-2x6 (H++), introduced in 2023, [2] [3] which changed the GPU- and PSU-side sockets to ensure that the sense pins only make contact if the power pins are seated properly. The cables and their plugs remained unchanged.
A six-way connector on a "universal" DC power supply, consisting of a four-way X connector and two separate individual connectors (one is the nine-volt battery connector). The X-connector here provides 3.5 and 2.5 mm phone plugs and two sizes of coaxial power connector Universal laptop power supply with adjustable voltage between 12 and 24 volts
The connector typically has 2 to 24 contacts and is polarized or keyed to ensure correct orientation. Pins and sockets can be arranged in any combination in a single housing, and each housing can be either male or female. There are three typical pin sizes: 1.57 mm (0.062 in), 2.13 mm (0.084 in), and 2.36 mm (0.093 in).
