Rectangular Connectors - Housings

The 1612035-2, or commonly known as the “3M™ Tri-Start Series Connectors,” are a unique class of rectangular connectors that provide superior durability and environmental resistance when used in harsh environments. This series of connectors is designed to utilize a “tri-start” design, which uses three separate contact points to ensure reliable connectivity and high signal integrity. This series is available in multiple sizes and configurations to meet the specific needs of many applications, including medical, mission-critical, and industrial.

Application Field

The 1612035-2 is primarily used for connecting and protecting sensitive electronic devices in harsh environments. Approved to meet IP68 standard, the series provides water and dust proofing for industrial, marine, and operation theatre applications, and is suitable for applications ranging from medical to mission-critical. In addition, these connectors are also suitable for computer, airplane, and automotive applications, due to their highly reliable vibration proofing characteristics. The use of these connectors are not limited to harsh environments and are heavily used for securing signals, surge protection and ground points, even in low-voltage applications such as light or low-current wiring.

Working Principle

The 1612035-2 provides 3 separate contact points, or ‘points of engagement’, between the connectors which ensures a highly reliable and low signal-loss connection. First, two of the contact points look like two intersecting circles that connect the two connectors. The third contact point consists of a round cross-section and flat tip that is pushed securely into the wedge-shaped groove. When the connectors are mated, the wedge-shaped groove latches securely against the two ‘intersecting circles’, creating the circular contact point. This creates a robust connection, and prevents the connection from disconnecting or slipping out after long periods of use.

The connectors are designed to be highly resistant to shock, vibration, and environmental contaminants. These connectors feature a unique seal that forms a seal between the two connectors, which provides better shock and vibration resistance as compared to traditional connections. In addition, the connectors include a dust cover that is designed to protect the connection from dirt, dust, and other contaminants.

In addition, the 1612035-2 features a ‘travel limiter’ that helps to prevent accidental disconnection. The travel limiter is designed to keep the connectors securely mated, regardless of how much force or tension is applied. This feature is especially useful in applications that require a secure and reliable connection while in transit.

Conclusion

The 1612035-2 series of connectors provide superior durability and environmental resistance when used in harsh environments. With 3 points of contact, the series provides a secure and reliable connection in a wide range of applications. In addition, they are also vibration proof and water/dust proof, making them the perfect choice for harsh-environment applications.
