RS PRO 25 Way Panel Mount D-sub Connector Plug, 2.77mm Pitch

From RS PRO a durable, highly reliable D-Subminiature connector designed for use in environments where high reliability is key. This connector has a steel shell and a diallyl phthalate insulator. Diallyl phthalate is a type of plastic which has good electrical properties, high heat resistance, good dimensional stability and high strength. The qualities of this material enhance the electrical performance of the connector. This connector is a commercial version of M24308 military connectors.

Solder bucket contacts

A D-Sub connector is a popular type of I/O (input/output) connecter that is commonly used in the computer and datacoms industry to provide power and point-to-point communications between two devices such as a computer and a monitor. The d-sub contains two or more parallel rows of pins or sockets surrounded by a D-shaped metal shell which provides mechanical support and ensures the correct orientation is used when mating. These d-subs are available as female D-sub sockets (or d-sub receptacles) with female contacts or male D-sub plugs with male pin contacts. The socket style female connector mates with the plug style male connector. Please note that a D-sub with a plastic shell cannot be mated with a D-sub with a metal shell.

These d-subs feature solder cups which are hollow cup-like cavities into which the wire is inserted and secured by soldering. Firstly make sure the connector is held securely while working on it. Strip the ends of each wire using the depth of solder cups to gauge how much insulation you need to remove. Tin the exposed wire strands with a soldering iron and partially fill the solder cup with solder. Apply a soldering iron to the edge of the cup allowing the solder to melt. Insert the end of the tinned wire into the cup and hold it in place until the solder becomes solid. If the wire gauge is large enough to support itself in the cup place it in the cup and feed in the solder whilst applying the soldering iron to the back of the cup.

These d-subs are designed to be panel mounted. A hole is cut in the panel which is determined by the panel cut-out dimensions of the plug or socket. Two mounting flanges either side of the connector incorporate mounting holes. Holes are drilled into the panel to align with these mounting holes. The connector is then inserted into the panel cut-out and secured in place by inserting screws through the holes in both the connector and panel.
