D-Sub Connectors

A D-Sub connector is a type of electrical connector that is widely used in the electronics industry. It consists of two or more pins or contacts which are held together by a metal shell and are usually mounted on a printed circuit board (PCB) or backplane. The design of the D-Sub connector makes it highly versatile in terms of application field and working principles.

The 182-009-112-561 D-Sub connector is a 9-pin connector that is commonly used for audio and video applications. The connector includes two types of contacts, an insulation displacement contact (IDC) and a solder contact.

The insulation displacement contact (IDC) type is the most common. It uses two pieces of conductive metal to make electrical contact. One piece is a flat spring-like piece which is pressed against the insulation between the contacts. The other piece is an insulated blade which is pushed in between the contacts to make contact. The IDC-type contact is used primarily for low-voltage and low-current applications.

The solder contact type is used for higher current and voltage applications. It uses two pieces, a copper contact which is pre-tinned and a contact pin to complete the electrical contact. The pre-tinned copper contact is soldered onto the contact pin which is then inserted into the D-Sub shell. The pin is secured using a locking mechanism.

The 182-009-112-561 D-Sub connector is highly versatile and can accommodate a variety of audio and video signals. Its robust construction makes it suitable for many industrial, consumer, and automotive applications. The IDC-type of contact is used for low-voltage and low-current applications, while the solder contact type is used for higher current and voltage applications.
