D-Sub Connectors

D-Sub connectors are a type of electrical connector commonly used in the telecommunications, computing, and industrial automation markets. They are designed to provide reliable electrical connections between two or more modules, often through multi-pin wiring configurations. The primary components of the D-Sub connector are a set of metal shells, contacts, and insulation material.

DEM9SF179A Application Field and Working Principle

The DEM9SF179A is a type of D-Sub connector designed for reliability and performance in harsh conditions. It features an industry-standard 9-pin wire-to-wire contact configuration and is suitable for use in a variety of applications, including aerospace, military, and industrial automation. The DEM9SF179A connector has a rated mating cycles life of up to 5000 cycles, a nominal voltage of 1KV, and a current rating of 6A.

The DEM9SF179A connector utilizes a threaded coupling mechanism for reliable connection, and has a built-in latch retention system for secure and repeatable mating. The connector utilizes two shell components: an outer shell with threaded inserts to hold the contact pins in place; and an inner shell with threaded screws to ensure secure contact and electrical connection. The electrical contact pins used in the DEM9SF179A are typically made from copper or brass and are made to provide reliable electrical contact in low- to high-voltage applications.

The DEM9SF179A connector is also designed to provide shielding from electromagnetic interference (EMI). The connector utilizes a special type of EMI shield that is integrated with the contact pins and is designed to block the passage of disruptive electrical signals from the external environment. The EMI shield also serves to protect the contact pins from dust, dirt, and moisture.

The DEM9SF179A connector is designed for use in a variety of harsh environments, including extreme temperatures, vibration, dust, and moisture. The connector is also resistant to corrosion, making it suitable for use in outdoor and marine applications. Additionally, the connector is RoHS compliant and UL listed.

In summary, the DEM9SF179A is a reliable, high-performance D-Sub connector designed for use in a variety of applications. The connector features a 9-pin wire-to-wire contact configuration which provides reliable electrical connections, a threaded coupling mechanism for secure mating, and an integrated EMI shield to block signal interference from the external environment. The connector is RoHS compliant and UL listed, making it suitable for use in a variety of harsh environments.
