122A13119X

The DIN 41612 connector is a modular backplane connector system which is designed to minimize power losses and make efficient use of space in applications where many contacts have to be present. It is one of the most commonly used connectors in industrial and consumer electronics applications. The DIN 41612 connector is a standardized interface whose 12-way, in-line design is easily adaptable to many different power, signal and data transfer applications. The two most popular versions are the 122A13119X-series, used in aerospace and industrial applications, and the 122A13119X2-series, used for personal computers, telecommunications and electronic equipment.

122A13119X Application Field and Working Principle

The 122A13119X connector is a high-density connector series developed for many industrial and aerospace applications, including high-speed data transmission. Its housing is made of plastic or die-cast zinc with gold-plated contacts for use in high-reliability applications. It has a narrow pitch of 2.54 mm and features three rows of four contacts on each side of four contact rows to provide a total of 12 contacts in a single row, with staggered pin layout for improved mechanical stability.The 122A13119X connectors have an optimized mechanical design which provides self-guiding polarization with three contact orientations. This allows the connector to be mated in any orientation to ensure an accurate and secure connection. The connector has surface mount or through-hole contacts which accept wire or printed circuit board (PCB) contact termination.The contact arrangement of the 122A13119X is designed to allow fast and easy assembly, with strong mating force retention and reliable signal transmission. It employs a dual beam contact design, which distributes contact forces more evenly across the contact area, minimizing internal resistance and improving cold pull tab resistance. It is also designed to minimize the effects of insertion and removal on electrical performance. The connectors are designed to withstand extreme temperatures and power fluctuations and can sustain up to seven times the rated current.

Conclusion

The 122A13119X connector series is a popular choice for many industrial, aerospace and consumer electronics applications due to its high-density and robust design. It is easy to assemble and offers reliable power and signal transmission. Furthermore, its design allows for flexibility in mating orientation and its dual beam contact design ensures strong mating force retention and reliable signal transmission. With the ability to tolerate extreme temperatures and power fluctuations, the 122A13119X is an ideal choice for many high-reliability applications.
