Backplane Connectors - DIN 41612 are four row connectors situated between two PC boards and mainly used in backplane applications. They provide a way of linking a number of PC boards together, up to as many as 16, so that the data between them can be transferred.

One of the most popular types of DIN 41612 connectors is the 4-1392009-4. This type is an 8-bit, low-voltage connector suited to use in a variety of electronic equipment including fire alarm systems, broadcast equipment, office machinery, test instrumentation, and computer systems.

The 4-1392009-4 connector has four rows designed to accept either 8 or 12 contacts per row. The outer two rows are composed of two pin contact strips, each spaced by two pitches, allowing the contacts to stand higher than the middle two rows. This design provides fantastic connections without having to sacrifice board space.

The 4-1392009-4 connector has several key features that make it the ideal solution for connecting PC boards. It has a maximum current rating of 1,500 mA, a dielectric withstanding voltage rating of 1,110 VAC, and an operating temperature range of -25°C to +85°C. Furthermore, the connector has a plugging time of 5 seconds or less and a maximum contact resistance of 20mΩ.

The 4-1392009-4 connector has many applications in the modern day. It is increasingly being used for rear panel connectors in such devices as computers and monitors as well as for monitoring and control equipment. It is also used for cabling and power supplies in safety critical applications, such as fire alarms, as well as for specialized industrial equipment.

The working principle of a 4-1392009-4 connector is relatively simple. A housing unit has four rows of contacts and each row has either 8 or 12 contacts. When the housing and contacts are mounted to the PCB, the contacts can then be populated in the board. Once the contacts are populated, a plastic cover housing is slid over the contacts, pushing contacts into the contact holes of the board. The connection is made when the contacts have gone all the way into the holding holes, and the cover housing locks it into place.

This is the basic procedure of the 4-1392009-4 connector. The design stays the same across multiple versions of the connector, however, they may have slight differences in terms of size, contact types, and other features. Despite these minor differences, their working principle remains essentially the same.

In conclusion, the 4-1392009-4 connector is a popular 8-bit, low-voltage connector used in a variety of applications including computers, monitors, fire alarms, broadcast equipment, office machinery, test instrumentation, and industrial equipment. It has maximum current rating of 1,500 mA, a dielectric withstanding voltage rating of 1,110 VAC, an operating temperature range of -25°C to +85°C, a plugging time of 5 seconds or less, and a maximum contact resistance of 20mΩ. The working principle is relatively simple, with a housing unit and four rows of contacts. The contacts are populated in the board, and a plastic cover housing is slid over the contacts, locking it into place.
