D-Sub, D-Shaped Connectors - 211669-1 Housings

A 211669-1 housing is a type of D-sub, D-shaped connector commonly used in the industry. This connector is made from die-cast zinc alloy and typically comprises of two separate, equal-sized and semi-circular ‘shell’ parts that contain pins or contacts for pulse communications. By interlocking the two parts, the housing forms a securely locked connector.

The 211669-1 connector housing is particularly useful for high-performance applications due to its capability to support higher performance data rates over relatively long distances. As such, this type of connector is frequently used in within industrial communication systems, such as those found in routers, switches, modems, satellite receivers and a range of other electronics.

Working Principle

The 211669-1 housing uses crimping technology for connection. This technology works by inserting the wire into the connector and applying pressure and heat, which causes the metal (normally copper) to deform and sustain contact. This superior connection method is very reliable, enabling the connector to maintain a positive contact even when external forces are applied to it, such as when the device is bumped or dropped. The outer shells of the connector also serve to protect and strengthen the connection.

The 211669-1 housing also has a lower contact resistance than most other types of connectors. This helps to reduce resistance and noise in data signals, resulting in clearer and more reliable communication performance over extended distances.

Applications

Due to its superior performance qualities, the 211669-1 housing is used widely in a variety of applications, such as industrial automation, building and system automation, robotics and motor control, communication and data networks, biomedical systems, security systems, and military equipment. It is also suitable for use in high vibration environments, making it a reliable choice for tough, long-term applications.

The connector is also a popular choice for applications that require a hermetically sealed connection. The two shell-like components allow the connector to provide a uniquely tight and secure seal, protecting it from dust, water vapor, and other potentially damaging external elements.

The 211669-1 housing is typically designed for use with various standard low-temperature thermoplastic insulators. This allows it to perform in extreme temperature environments, from -55°C to 125°C, making it an ideal choice for harsh industrial and outdoor applications.

Conclusion

The 211669-1 housing is a reliable, secure and durable type of D-sub connector that is ideally suited for industrial communication systems and numerous other applications. It provides a secure hermetic seal to protect against dust and other external elements, while the lower contact resistance enables it to maintain reliable data transfer over distance. In extreme temperature environments, the connector can also perform up to temperatures of 125°C.
