216398-4

Backplane Connectors, specifically DIN 41612 connectors are commonly used in applications requiring reliable and secure electrical connections between printed-circuit boards (PCBs) and chassis. The 216398-4 series of DIN 41612 connectors is used especially in Data Communications, Industrial Automation, Telecommunications, Networking, Signal Processing and Data Acquisition applications.

The 216398-4 design is a shielded 2ROW vertical mount connector featuring two rows of 16x74V (3.96 mm) centers with 74 contacts (maximum). It helps ensure dependable, secure connections even in high-speed and amplified systems, as well as reduces overall system sizes. It is designed for frequencies up to 500 MHz and offers contact durability up to 500 mating cycles.

In addition, the 216398-4 connector is RoHS & UL compliant and features two grounding points. The four-point system connection makes it possible to achieve secure mating easily, even on printed-circuit boards with no machining provided. The 216398-4 series is ideally suited for demanding applications and environments such as in-car computers, industrial fieldbus solutions and powered mobile equipment.

Knowing the 216398-4 connector’s working principle and application field is important, because understanding how and why these connectors work is key to successful integration into a wiring assembly. In order to function, the 216398-4 assumes the basic principles of shielding and ground plane construction.

The 216398-4 connector includes a metal shield that surrounds the contacts as a conductor which helps provide galvanic insulation of the contact points and suppresses interference. It shields the contact points from external electric and magnetic fields and also shields external leakage from entering the contact points. The connector is designed to be positioned and mounted to a ground plane on the PCB, which reduces overall size and helps improve heat transfer.

The 216398-4 connector features a self-mating design, allowing each piece to slide together and lock. This is achieved by the use of a separate gasket that provides the compression force necessary for a steady connection, which also helps prevent disconnects due to vibration. Once the gasket and contacts have been fully engaged, the end forces prevent disconnection in even the harshest environments.

The 216398-4 series of DIN 41612 connectors by Backplane Connectors offer a reliable and secure electrical connection between a board and a chassis and are ideal for a wide range of applications. Knowing the working principle and application field is essential for the successful integration of the 216398-4 into a wiring assembly.
