Rectangular connectors are a type of connector typically used in industrial or automotive applications. They can be simplex, duplex, or multiplex; however, the most commonly used type is the single-sided, which is used in a variety of applications. The 171822-9 is one of the most popular varieties of rectangular connectors due to its small size, high electrical and mechanical reliability, and excellent contact resistance.

The 171822-9 is typically available in two different housing configurations, including a standard housing and a smaller, mini-housing. The traditional style is the most popular, offering the highest electrical current capacity and rated up to 25A. The mini housing is compact and best suited for applications with space restrictions. Additionally, the mini housing is typically rated up to 15A.

The 171822-9 housing is typically constructed of high-temperature thermoplastic material – polyamide based. This material has the ability to withstand high levels of vibration and shock in industrial environments. It is also extremely resistant to oil, chemicals, and water. The housing is designed with a locking mechanism that is actuated with a wire and the connector slides into a groove.

The 171822-9 housing has a total of twenty contact positions, with two each at the top, bottom, and sides, and four each at the front and rear. Each contact is rated up to 2.5A and four of the contacts feature 6.3mm press-fit terminals. Depending on the application, higher rated contacts are available. Additionally, the contacts are protected from debris and other contaminants.

The 171822-9 housing features a series of pins and sockets making it a polarized connector. The pins are typically designed with one or two plated sprinclaws, and are installed into corresponding sockets. The sprinclaws ensure ease of mating, with the contacts of the mating connector compressing the sprinclaws firmly against the socket. This helps to ensure small vibrations do not separate the connection.

The 171822-9 connector housing is typically rated up to 300V and 500V in case of high current contacts, making it suitable for a range of applications involving high-voltage electrical potentials. The housing is also sealed against water ingress with an IP67 rating, and resists salt fog, shock and vibration.

The 171822-9 connector is widely used in industrial, automotive, and other applications where reliable connection and high-voltage requirements are needed. It is a popular choice for many complex systems, and its rugged housing makes it suitable for use in harsh environments. Additionally, its small size and relatively high current ratings make it ideal for applications with limited space.
