Safe power transmission with new power connectors

Paul Boughton
Embedded computing systems based on the MicroTCA standard (Micro Telecommunications Computing Architecture) are now used not only in the telecommunication sector, but also in areas like industry, the military, and traffic or medical technology.

The PICMG MicroTCA.0 basis specification relies on the use of Advanced Mezzanine Cards (AMC). The small footprint of the AMC allows systems to be built in extremely compact and robust form.

For shelf management, the system can be assembled with an MCH plug (MicroTCA Carrier Hub). Yamaichi offers suitable connectors that are especially notable for their high-speed transmission properties.

Besides high-speed signal connectors, Yamaichi Electronics  also has MicroTCA power connectors in its product line.

MicroTCA power connectors are implemented as a 96-pin version and are compliant with the PICMG specification. Besides the 72 signal pins, there are 24 power contacts available for transmission of more than 11A. The robust plug housing design allows blind plugging. The angled male connector is used on the Advanced Mezzanine Cards for this purpose; a straight version of the female connector is installed on the backplane. Due to the leading and lagging contacts, the connectors are hot-swap capable. Standard press-fit tools can be used to mount them onto the backplane or the Advanced Mezzanine Card.
