D-Sub, D-Shaped Connectors have been used for a variety of applications, from telecommunications and electronic equipment to high-end industrial applications. The 204351-1 is one such D-Sub connector, and is primarily used for the transmission of digital and analog signals.

Application Field

The 204351-1 is designed for use in military, space, and high-performance applications. It provides robust performance in harsh environments with extreme temperatures, vibration, and magnetic fields. It is also designed for use in high-speed applications, such as high-speed Ethernet and digital transmission systems. The 204351-1 is fully compliant with MIL-STD-1553, the military specification for bus architecture, and can support data transmission rates up to 100 Mbps. The connector has a high current rating of 5A per pin, making it suitable for a variety of high-power applications.

The 204351-1 supports up to 50 pins, with two shell sizes: 2x25 and 2x50. It is a shielded connector, providing additional protection from external interference. The connector is also designed for blind mating, allowing for quick and easy installation in tight spaces.

Working Principle

The 204351-1 is a press-fit connector, designed for mating digital or analog signals. The electrical contacts utilize a three-barrel design, providing a low-resistance connection and a secure mechanical engagement. The contacts are corrosion resistant and provide a high degree of reliability, as they are designed for thousands of mating cycles.

The 204351-1 utilizes a standard insulation displacement contact design. This design uses a wire-size pre-programmed, semiconductor device that precisely guides the contact into the insulation for a secure connection. The contact is then pressed into the insulation material with a mechanical force, providing a permanent, low-resistance connection.

The contact’s gold-plated surface provides additional corrosion resistance and also a low contact resistance. In addition, the contact can accommodate a variety of wire gauges and insulation types.

Conclusion

The 204351-1 D-Sub Connector is a high-performance contact designed for use in military, space, and high-performance applications. It provides a robust connection and superior resistance to harsh environments. The connector is designed for blind mating and supports up to 50 pins. It is a press-fit connector with a three-barrel design and a gold-plated surface, conferring corrosion resistance and a low contact resistance.
