The PCI Industrial Computer Manufacturers Group recently released an addition to the MicroTCA family of specifications. The Air Cooled Rugged MicroTCA specification extends MicroTCA into applications beyond its original telecommunications focus.
MicroTCA specification developers choose rugged and reliable combination D-subminiature connectors as the power input interface.
MicroTCA uses specific connector variants for various input voltage levels:
- 7W2 variant - 48 V
- 9W4 variant - 24 V
- 5W5 variant - 12 V
- 15W4 high density variant - 12 V
Positronic's "QB" series offers all four Combo D variants included in the MTCA specifications and offers a variety of features:
- Single or stacked dual port package
- Right angle PCB mount connectors offer standard mounting brackets or a unique "low profile" design which reduces the height of connectors off the PCB
- Power contacts have resistance values as low as 0.00035 ohms
- Current ratings as high as 80 amperes, when tested per U.L. 1977, are available. For details, see temperature rise curves in product literature. This is achieved with the use of high conductivity contact materials.
- Cable connectors are available with short hoods with internal cable clamps suitable for use in tight spaces
- A full range of contact plating options including military grade
- Power contacts have high reliability closed entry female as standard. Signal contacts are available with closed entry contacts options
