D-Sub, D-Shaped Connectors - Contacts

D-Sub connectors are one of the most popular types of connectors available today. The D-shaped connectors are named for their unique shape, which is formed by two flat sides and two round sides. The shape of the D-Sub connector makes them easy to recognize and easy to interface with other types of devices. DM53744-109 is among the most widely used D-Sub connectors on the market today.

Application Fields

DM53744-109 is widely used in many application fields. It’s perfect for applications that requires a reliable connection in areas with high electrical interference. Common applications include equipment with high voltage, high current, and high frequency electrical components. Examples of these include digital audio/video equipment, computer devices, medical equipment, instrumentation, and automotive applications.

Working Principle

DM53744-109 is a low profile, panel mount, D-shaped connector. It has two rows each containing 9 pins. It also has multiple mounting screws that facilitate secure panel mounting. The housing is made of a rigid and robust polycarbonate material, making it suitable for a variety of operating environments.

The pins on the DM53744-109 are securely locked in place due to the springs on the back of the pins. When a signal is applied to the connector, the pins are pushed out from the front of the connector and electrical connection is established. This is known as a “pull out” design and is employed in many connectors due to its reliability and low profile. The housing also helps keep the pins securely in place even when the connector is exposed to vibration or extreme temperature.
