D-sub, d-shaped connectors are commonly found in a variety of applications, from consumer electronics to a wide range of business and industrial applications. The configuration of these connectors, also known as High-Density(HD) connectors, is what makes them extremely versatile and reliable in virtually any environment. Commonly used in many industries, these connectors have evolved over the years to meet the demanding requirements of the most challenging applications while addressing the changing needs of today\'s technology. The XM4Z-0021 is a special type of d-sub connector designed for use in a variety of high density applications.

XM4Z-0021 is a high-mylar insulator-made crimp contact connector. It has 21 pins, four rows; two rows each with eight pins and two rows each with four pins. The entire unit has a two-row design, which is more suitable for higher altitude application fields, such as in motherboard, LCD, MRAM, or backplane applications. The pins are made from tinned phosphor bronze with insulation, which is extremely resistant to corrosion and further guarantees a secured connection. The contact pins are also gold plated, giving this d-shaped connector excellent electrical conductivity.

Aside from providing high density connections, the XM4Z-0021 also features an elastomer seal and contact ramps that lock when the connector is properly mated, providing a secure seal that is highly immune to shock, vibration, and most environmental influences. The connector\'s high mating and unmating characteristics make it highly suitable for applications that require frequent reconfiguration, such as mobile applications. Furthermore, XM4Z-0021 also has excellent EMI protection characteristics due to its four-row EM shielding structure, which is composed of an elastomer that contains conductive particles.

When it comes to the working principle of XM4Z-0021, it works in a relatively simple way. When a plug and receptacle are connected, the contacts are simultaneously pressed into the contact bore between the elastomer sealing elements and the contact ramps. This elastic contact clamping removes undesirable contact forces and keeps the electrical contact resistance low. At the same time, the contact ramps provide mechanical locking and electrical shielding. In the event of environmental influences, the SEAL-LOCK ensures mechanical reliability and prevents power loss.

In summary, the XM4Z-0021 is a reliable and versatile high density connector that is suitable for a wide range of applications. Its four-row EM shielding structure and mechanical locking features make it highly suitable for applications that need to be constantly reconfigured and environments with heavy environmental influences. Furthermore, its high mating force and low contact resistance also make it a highly reliable connection. It’s easy to see why XM4Z-0021 is a popular choice in various industries.
