D-Sub connectors are widely used in many electronic application fields, including computer peripherals, telecommunications, medical instruments, industrial electronics, and instrumentation. The L77TWC21WA4SHCSV series of D-Sub connectors are specifically designed for applications that require high performance and flexibility. This series of connectors feature two different shell sizes, two color shell options, and multiple contact configurations and polarizations (9, 15, 25, 37, or 50-pin variants).

The L77TWC21WA4SHCSV series of D-Sub connectors are designed for easy installation, allowing quick and easy connection to a computer or other equipment. The two-part steel shell provides a firm connection and prevents contamination from interference. Its durable housing also provides robust resistance to shock and vibration, making it suitable for rugged applications. Additionally, the connector comes with built-in strain relief to help secure cables and increase the longevity of the connection.

The L77TWC21WA4SHCSV series of D-Sub connectors use a two-part system for their contact arrangement. This contact system is composed of an internal female contact and an external male contact, each with multiple contact configurations and polarizations. The internal female contact consists of three or four individual terminals that can be configured to provide different contact polarities. The external male contact, also referred to as the hood, contains an insulating shield that can provide up to 500 volts of insulation between the contacts.

The L77TWC21WA4SHCSV series of D-Sub connectors are available in multiple variations, such as the High-Density (HD) version, which allows for more efficient use of space in an electronic panel. Another variation is the HD version with an anchor-mounting option, which allows the connectors to be mounted directly onto a PCB. For additional mounting options, the L77TWC21WA4SHCSV also features a rear-mounting option and a variety of plated seals.

The working principle of the L77TWC21WA4SHCSV series of D-Sub connectors is based on the electrical contact of two dissimilar metals, usually copper and brass. This contact creates a low-voltage electric current between the two metals, forming a conductive pathway through which data and power can be transmitted. When connected, the two different types of metals create an electrical connection that provides an uninterrupted signal path for electricity or data signals.

The L77TWC21WA4SHCSV series of D-Sub connectors are able to meet the highest performance requirements due to their combination of excellent electrical performance, high quality construction, and reliable connection. These benefits make the L77TWC21WA4SHCSV series the ideal solution for applications that require a secure, high-performance connection in a variety of industrial, instrumentation, and computer-related applications.
