D-Sub Connectors

D-sub connectors are one of the most popular and versatile connectors in the world, characterized by their unique combination of connector design, contact layout options and terminal assignability. The DDMM-50P-L is a type of D-sub connector with 50 pins. It can be used for a variety of applications, such as DMX (acronym for Digital Multiplex), MIDI (Musical Instrument Digital Interface) and video/audio connections.

Application Field

D-Sub connectors like the DDMM-50P-L offer a versatile range of uses, such as data transmission, communication, signal processing, power distribution and data protection and/or signal conditioning for automotive, aerospace and industrial control applications. The DDMM-50P-L is able to handle 9-pin through 90-pin contacts and larger-diameter pins provide greater contact assurance and increased current capacity.

Working Principle

The DDMM-50P-L working principle is similar to the other types of D-sub connectors. It is designed with a contact system architecture consisting of a pin row and a socket row. The connection for each pin is made up of two metal contacts, one soldered to each side of the contact and the other one to the extending dead wedge or “pinning”. The contact must be ordered in the proper orientation so that the contact and pinning can be soldered and pinned together. The two mating contacts are then trapped together by the mated plug and socket.

The contact system of the DDMM-50P-L combines high mechanical stability and high contact density, allowing for the transmission of reliable, high-quality signals. It also provides support for hotplug connection modes which allow the user to plug and unplug devices safely while maintaining a high signal quality level. Furthermore, the DDMM-50P-L features an EMI/RFI shielding system integrated into its cable and EMI interface cable which helps prevent signal interference and line noise.

Benefits

Besides its versatile and reliable performance, other benefits associated with the DDMM-50P-L include a higher packing density for smaller connections, an improved cable shielding for greater EMI/RFI protection and a secure mated connection with no chance of accidental uncoupling or misalignment.

The DDMM-50P-L is a reliable, versatile choice for a broad range of applications and is one of the most popular and trusted connectors of its kind. It is ideal for applications in the automotive, aerospace and industrial control industries due to its impressive range of features and benefits.
