DIN 41612 is a specification of backplane connectors that is primarily used in Compact Peripheral Component Interconnect (CPCI) applications. This specification is developed by and named for Deutsches Institut fur Normung (DIN), an international standard organization. This connector type is often referred to as a compact stab, or a rectangular mated pair, connector.

The 72904-223 backplane connector from DIN 41612 is a three row right angle, male connector. It uses the same contact layout as described by the DIN standard, with three rows of signal contacts and two rows of key contacts for polarizing and keying purposes. All three rows of signal contacts are configured as ‘super co-axial’ contacts, each contact having a maximum current rating of 8.5A. The connector also features an integrated twist and pull protection for improved robustness and security.

The 72904-223 from DIN 41612 meets the requirements defined by the DIN 41612 specification, offering optimal electrical performance and reliability in industrial, telecommunications and other applications. It is specifically designed to provide reliable and secure signal integrity in a wide variety of backplane configurations.

The 72904-223 offers excellent shielding properties and superior electrical protection. Its contact assembly uses a slide-in technique that allows for easy and reliable contact insertion. The contact design is staggered to reduce frequency-dependent cross talk, and an integral twist and pull protection gives added assurance and improved robustness. Additionally, the contacts are plated with a Nickel-Barrier and Tin finish for superior corrosion resistance.

The 72904-223’s backplane connector utilizes a standard stacking design, with a standard pitch of 2.5mm. This ensures that the connector can be used with all popular Compact Peripheral Component Interconnect motherboards and backplanes to provide signal integrities. The key spacing of the receptacle is 5mm, offering secure polarisation and keying to ensure a proper connection and all connectors have a minimum contact retention force of 30N.

The 72904-223 offers a reliable and secure connection for a wide range of applications. With its combination of robust construction, superior electrical protection and reliable signal integrity, this backplane connector is an ideal choice for any project requiring a high-quality connection between components in a Compact Peripheral Component Interconnect system.
