Introduction
Product Overview
The Amphenol DSub TW Hybrid Series offers a versatile solution for mixed-contact connectors, integrating signal, power, shielded, and high-voltage contacts within a single housing. Evolving from a military-grade design, this economic series features enhanced components including new contacts and a high-temperature black thermoplastic insert. Preloaded PCB configurations with fixed contacts and brackets ensure ease of use. These connectors are supplied with screw-machined contacts secured in the insulator, with a comprehensive range of housings available for cable applications. Ideal for commercial, medical, industrial, and telecommunications sectors, this series is designed for applications requiring optimized space and reliable performance.
