D-Sub Connectors are a type of electric connector designed to join two devices in an application. The 1218532-1 is a D-Sub connector, and its field of application and working principle will be discussed in this paper.

This particular D-Sub connector comes with the female end having a 9mm shell and a maximum current of 10A, and the male end having a 9.5mm shell and a maximum current of 8A. It has a screwlocking retention and can be wired in configurations of 2 to 3 positions. It also features a one-piece design with a reliable connection performance.

The 1218532-1 is generally used for multipurpose wiring applications in the automotive, railroad and industrial sectors, such as in engines, driving systems or signals. It is suitable for harsh environments, boasting exceptional heat resistance, alongside being shielded against electromagnetic interference and excellent noise control, along with maximum current and insulation voltage of 10A and 250V rms respectively.

The working principle of this D-Sub connector is based on each outlet having an internal male and female contact, which can be secured through a square nut connection or a inner and outer locking mechanism. During installation, the two contacts are connected together so that electricity may flow between the two outlets, providing a secure connection. As a screwlocking retention connector, once it is locked it provides the least possible electrical connections and excellent leak-tightness.

The 1218532-1 D-Sub connector is used in a wide variety of applications due to its combination of reliable performance, easy installation and maximum connection efficiency. Its 9mm and 9.5mm shells, along with its shielded design and insulation voltage of 250V rms, help to provide protection in potentially harsh electrical applications, making it suitable for use in the automotive, railroad and industrial sectors. Its use of a screwlock retention, alongside its internal male and female contacts, not only result in a quick and secure connection, but also ensures minimal electrical connections, making sure the connection remains secure.
