Connector type 202135-4, also known as 26482, is a backplane connector for housing applications. This connector is especially suited for high-speed data transfer and is part of the well-known mil-spec 26482 family.

The 202135-4 of high-speed backplane connectors was developed by LEMO and features a 2mm pitch with a 2x50 contacts array. It has gold over nickel-plated contacts for maximum durability and longevity and high vibration resistance. This type of connector is essentially a housing with contacts suitable for paralleling, grouping or interleaving of multiple electronic components and cables to form a more complex, larger system. Connectors like these offer an effective and organized way of connecting components, allowing for easy and convenient assembly and disassembly of the system, and also the option of swapping or expanding components as needed.

The mil-spec 26482 family of connectors is compliant to industry standards, and is useful in any environment where insulation and high performance is needed. The connectors are available in 1x14, 2x17, 2x22, 2x50 and 3x44 terminations, providing designers with many options in terms of size, power handling and other performance related metrics. Mil-spec 26482 is suitable for a wide variety of applications, including aerospace, military, medical, industrial, computers, and consumer electronics.

The 202135-4 consists of a housing called the Flange Edge Housing, which is the protection and support enclosure for the contacts and is made from anodized aluminum alloy. This housing provides a water resistant seal that helps keep moisture out. There is also an insulator that comes installed into the housing and helps keep the contacts insulated from other components in the system. The contacts are made of spring pressure gold plated Beryllium Copper and are pre-assembled, allowing for easy installation into the housing.

The behavior of the contacts is determined by the contact layout and the contacting force, as the contacts must be able to make a reliable connection with a minimal chance of interference. The contact force of the 202135-4 is adjustable and can be changed either mechanically or electronically. The amount of contact force will depend on the type of use and application and can be adjusted accordingly.

The 202135-4 offers exceptional performance in terms of high contact reliability, low insertion force, minimal cantilever bending, and low electrical resistance. It is RoHS compliant, which makes it even more desirable for various applications. Some of the other features of the 202135-4 include a fine pitch for high density connection, flexible plugging arrangement, completely shielded contacts, and a robust design for secure contacts in harsh environments.

The 202135-4 backplane connectors are versatile and reliable connectors that make it easy to connect multiple electronic components together in a system. The connectors are available in a variety of configurations and contact types, making them suitable for a wide range of applications and environments. The connectors are dust and water resistant, as well as vibration and temperature resistant, and can be adjusted for optimal performance. The mil-spec 26482 standard compatibility ensures the 202135-4 can be used in any system requiring high-speed data transmission without risk of interference or electrical issues.
