Micro-D Twinax Connectors

Micro-D Twinax Connectors (MDTX) offer twinax blindmate assemblies fitted into a low-profile metalized Micro-D style shell. This series allows for modularity of PCB routing of high speed signaling capable of 100 Ohm differential pair matched impedance for IEEE 1394b firewire and gigabit Ethernet applications in a size 10 twinax contact. These connectors allow for maximum space utilization, ultra miniature size, high vibration capability and are extremely light weight and modular with true signal integrity. Insert arrangements are available in 2, 4, 6 and 8 way twinax assemblies with mixed signal and power contacts available in hybrid layouts. These connectors are available with locking post mechanisms or blind mate features.
