The 3M Mini D Ribbon (MDR) Cable Assembly is a high-speed video data transmission system designed for demanding applications. Featuring a .050 pitch and 50 positions, this assembly supports LVDS Channel Link signaling, making it ideal for high bandwidth requirements. It offers robust construction with individually shielded twisted pairs, a high-density MDR connector with rugged ribbon-type contacts, and EMI shielding for reliable performance. The system includes 20 shielded pairs (100 ohm) and 4 drains, along with 3 unshielded twisted 28 AWG pairs. Designed for durability, it incorporates rugged thumbscrew retention for secure connections and is RoHS compliant.
