Introduction

D-Sub, D-Shaped connectors, sometimes called D-Subminiature connectors, are electrical connectors that feature two rows of pins or sockets usually surrounded by a D-shaped metal shield. They have a variety of applications ranging from PCB connectors to computer connectors. The 211651-1 connector is one of the connectors in this type of connector family.

211651-1 Application Field and Working Principle

The 211651-1 is a rear-mount D-subminiature connector which features a protecting cover and is PG-braised and UL-rated for high vibration/shock resistance. This connector is a perfect solution for applications with stringent requirements in terms of durability, vibration, and climatic conditions. It is highly used in the industrial and military fields due to its high durability, providing great flexibility for a wide range of applications. It can be used in harsh industrial environments.

The 211651-1 is composed of two mating connectors, one male and one female. It is designed with a square-in-square contact configuration due to the box configuration used. The box contact helps reduce the risks of contact fault which can benefit from the use of this connector in ruggedized applications. The pins/sockets are made of brass, which helps provide additional durability and stability of the connection. The contact pins are also gold plated to protect against corrosion and provide better electrical power transmission. The backshell of the connector is designed with a protective cover, which helps protect the contact pins from shock and vibration.

The 211651-1 connector has a male connector with 25 contacts and a female connector with 25 contacts arranged in two rows on each side of the connector. The contact pins/sockets are rated at 20-amp current, and the female-to-male connection is rated at 1500V for a maximum of 12 cycles at a given temperature.

The 211651-1 connectors feature a secure locking mechanism, which helps ensure a secure mechanical connection. The locking mechanism is designed to provide a strong connection that is resistant to vibration and shock. Additionally, the connector is designed with a polarization feature, which helps ensure that the connectors are accurately aligned for reliable electrical connections.

Aside from its technical specifications, the 211651-1 connector also has some additional advantages. It is easy to install and requires minimal force for proper insertion and removal. It also features an environmental protection rating of IP68. This ensures robust protection from dust and liquid penetration, making it an ideal choice for various applications.

Conclusion

The 211651-1 is a high-quality D-shaped connector designed to ensure reliable electrical connections in various applications. It features a secure locking mechanism, gold plated contact pins, a protective cover, and an environmental protection rating of IP68. This makes it an ideal choice for applications that require a reliable solution even when exposed to harsh conditions.
