148684-1

Backplane Connectors - DIN 41612 provide a high-speed signal transmission solution for many applications. They use a modular, field-repairable and quick-connect contact system, allowing the user to select appropriate contact density for the application and easily repair damaged contacts in the field. The standard contact arrangement allows for traces to be divided into precisely equal-sized segments for better margins and crosstalk isolation in high-speed wiring designs. The electrical contact reliability of these connectors and the ability to quickly replace damaged contacts makes them a preferred choice for many applications.

The 148684-1 is a type of backplane connector from the DIN 41612 series, available as a plug, receptacle or header. This series is designed to mount on a printed circuit board and its primary goal is to provide users with a cost-effective and high-speed signal transmission solution. It is suitable for both panel mount and protrusion mounting. It is a dual row connector with 12 gold-plated pins that can form up to 40 signal contact pairs. It is available with antistatic protection as standard.

The maximum current rating of the connector is 5A per pin, with an operating voltage of 250VAC. The operating temperature range is from -55°C to +105°C, while the contact resistance rating is 20mΩ max at an initial voltage drop of 5mV. It comes with an insulation resistance of 5000mΩ minimum at 500VDC. It also features a dielectric strength of 2500VAC (rms) between contact and ground, and 1000VAC (rms) between two contacts.

In terms of working principle, the 148684-1 functions by providing mating between its two parts, plug and receptacle. This mating takes place by coupling the solder tails of the plug to the pads of the receptacle, using either two- or four-point contact. The plug contains a spring-loaded dual row of pins that create contact points with the receptacle when it is fully inserted. In order for the plug and the receptacle to be correctly mated, they both must have the same number of pins and contact points.

The 148684-1 is available in several versions and options, such as right angle and vertical connection. It is usually employed in network communication systems, servers and high-speed wiring systems, and is compliant with RoHS, UL, and CSA standards. The 148684-1 provides a reliable, high-speed signal transmission solution for many applications, making it an excellent choice for users who need a cost-effective and durable solution.
