MHD Series

High density PCB connectors

Featuring the Hypertac® hyperboloid contact technology, MHD Series are high density board to board interconnects available in up to 400 positions, with insulators to accommodate coax and power contacts. Space grade/ESA/ESCC qualified are also available.

Features & Benefits

  • Signal and HE 807 cavities for power and coaxial contacts
  • Housing with ruggedized metal shell
  • High density: up to 400 signal contacts
  • Space grade/ESA/ESCC qualified available
  • Featuring Hypertac Hyperboloid contact technology


The MHD Series has been designed to resist the high levels of shock and vibrations in the harshest environments of the Commercial Aerospace and Space applications. The MHD connector is equipped with signal and HE 807 cavities for power and coaxial contacts. With a 0.5mm contact diameter, the series is available from 52 to 400 signal contacts with straight, surface mount tail and 90° termination styles and can support up to 32 power or coaxial contacts (2.00 contact diameter). The metal shell improves system reliability by ensuring high levels of shock and vibration and by eliminating contact fretting, hence reducing wear rates, and avoiding system failure and down-times.

    Understanding the Test Criteria of Optical Fiber Transceivers Used in Space

    In space, high performance components must be able to deliver reliably in the punishing environment. It is optical transceivers that drive transmissions, converting signals to and from a copper-resident format. Fiber optics communications provide high bandwidth and low latency signaling. Signal transmissions through fiber optic cables (FOCs) provide immunity to EM/RFI interference, crosstalk, and voltage level surges. Fiber optics’ accuracy and reliability exceeds traditional cabling. Covering 1,000 feet requires four pounds of FOC versus 39 pounds of copper wiring, and fiber optics also consume less energy than copper. To convert electrical signals from circuitries with copper output to fiber optics, optical fiber transceivers are usually required.
