More power to the backplane

Edited by the Electronicstalk editorial team Jan 20, 2005

A new hard metric power connector with a current rating up to 23A per contact provides a reliable and cost-effective solution for connecting plug-in units to backplanes.

Harting has a new hard metric power connector with a current rating of up to 23A per contact at 70C.

The new har-bus HM Power connector is designed to be used in conjunction with Harting's 2mm har-bus HM signal connectors, providing a reliable and cost-effective solution for connecting plug-in units to backplanes.

Both ranges of connectors meet OBSAI (Open Basestation Architecture Initiative) specifications, and offer full compatibility and intermateability with basestation modules.

The right-angle HM Power male connector for daughtercards can be supplied for either press-in or PIHIR (pin-in-hole intrusive reflow) assembly.

The compact high-temperature moulding can be loaded with up to four high current contacts.

Four different contact mating lengths make sequenced and non-sequenced loadings possible.

The straight female connector for backplanes is fitted with press-in contacts.

Each contact can carry up to 23A at 70C.

The footprint of the individual contacts on the backplane is symmetrical.

For boards with a thickness of at least 8mm, the connector can be pressed in from both sides, using the same holes, thereby saving additional space on the board.
