DIN 41612 is a type of backplane connector that is explicitly designed to facilitate the high density, modular interconnection of circuit boards. The components necessary to make such connections, are then classified into three distinct component groups that make up the DIN 41612 backplane system — namely, female receptacles, cable plugs and female pin headers. The specific DIN 41612 connector that will be the subject of this article, is the 5650870-4.

The 5650870-4 is a relatively small but extremely robust DIN 41612 backplane connector suitable for use with mezzanine circuit boards. It provides up to 44 signals and a maximum pin count of 88. It is enclosed in an all plastic, two part construction housing, providing better protection for the system and enabling increased power capability; both of which make it especially suitable for use in cramped or difficult to access locations.

These housings are filled with a specialised insulated material to protect the cables and contacts from damage and to maintain signal integrity under the influence of shock and vibration. As well as being shielded against EMI and ESD, this insulation also helps reduce the risk of arcing and failure due to excess heat. Additionally, the 5650870-4 connector has built-in supply voltage and overvoltage protection which helps to reduce contact resistance.

The 5650870-4 backplane connector is most commonly used in mezzanine connectivity applications such as in fields involving industrial automation, HVAC, electronics, communications, printing, railway systems, lifts, etc. As such, it is particularly suitable for applications where space is limited as is often the case in the previously mentioned industries.

In addition to its great versatility in applications, convenient size and durable construction, the 5650870-4 connector also stands out due to its reliable performance and the ease with which it can be installed. The connectors are designed to make a secure connection so there is no need to worry about debris or other contaminants entering the system. Furthermore, the installation of the connectors is easy and straightforward, thanks to the push-in connection system which eliminates soldering. This ultimately translates to a cost-effective and time-efficient approach to connector assembly.

In terms of its working principles, the 5650870-4 connectors are designed to ensure a reliable and secure connection between two systems, be they circuit boards or otherwise. The contacts of the connector are designed to ensure maximum contact area for reliable contact. This is further reinforced by the shielded housings which ensures EMI and ESD protection, and ensures that any contact resistance is kept to a minimum. The insulation also helps to protect the system from electrical shocks or overvoltage. Ultimately, this means that the 5650870-4 connectors provide a secure and reliable connection that is safe, reliable, and cost-effective.
