High Density Miniature
Circular Connectors
(HDMC)
HDMC 2010
Sabritec’s High Density Miniature Circular Connectors
(HDMC) have the performance of a MIL-DTL-38999
connector in a smaller size with significant weight savings.
These connectors are offered with Size 23 crimp
removable contacts or Size 12 High Frequency Coax
(MDHC) contacts and are compatible with industry
standard backshells.
MDHC Coax contacts have a frequency range up to 40
GHz and offer a low VSWR (1.3:1 typical up to 30 GHz and
1.5:1 typical up to 40 GHz) per mated pair.
A wide variety of high density space saving shell sizes with
Size 10 High Speed Twinax, rugged Fiber Optic signaling,
Coax, shielded Triax and EMI filtered layouts are
available in larger shell sizes. Size 10 Twinax/Quadrax
contacts are ideal for applications exceeding 2 GBits/sec.
Please consult factory for more information on alternate
shell sizes and layouts.
