D-Sub, D-Shaped Connectors - Housings

D-Sub (D-Subminiature) connectors, characterized by their distinctive D-shaped metal shield, are a widely recognized type of electrical connector used for reliable signal and power transmission. The housings in this category serve as the protective outer shells that securely hold the contacts and ensure proper alignment, shielding, and mechanical stability in interconnected systems. These components are essential for maintaining the integrity of connections in demanding environments.

This product classification includes various housing types designed for different D-Sub connector configurations, such as standard density, high density, and mixed-layout variants. Housings may feature materials like thermoplastic, metal, or composite alloys, offering varying levels of durability, EMI/RFI shielding, and environmental resistance. Common sub-types include solder cup, crimp, and PCB mount housings, catering to diverse assembly requirements in industrial, telecommunications, and computing applications.

When selecting D-Sub connector housings, consider factors such as gender (plug or receptacle), pin count (e.g., 9, 15, 25, or 37 positions), and shell size to ensure compatibility with existing hardware. Evaluate environmental needs options with IP-rated sealing or ruggedized designs are ideal for harsh conditions. For high-speed data applications, prioritize EMI-shielded housings to minimize signal interference. Always verify mating interfaces and mounting styles (e.g., through-hole, flange mount) to streamline integration. Investing in quality housings enhances connection longevity and system performance.
