Connector keeps VME64x backplanes in order
The new Har-bus 64S from Harting is a passive mechanical switching connector for use in VME64x bus systems.
The built-in switching elements close the daisy chain when no daughtercard is inserted, removing the need for active components or jumpers on VME64x backplanes.
The switching configuration is based on five pairs of switching contacts which short-circuit the VME interrupt lines when the daughter card is removed, preserving the integrity of the entire system.
The mechanical features of the switching elements guarantee reliable switching of the daisy chain without contact losses.
The switching elements are located in contact positions a21-a22, b4-b5, b6-b7, b8-b9 and b10-b11.
The new connector is an addition to Harting's har-bus 64 family, and is fully compatible with the daughtercard connectors in the range.
It also offers full backward compatibility with existing VME standard systems using 3-row type C daughtercard connectors with 2.54mm pitch according to the DIN 41612 standard.
har-bus 64 uses the same PCB layout and hole configuration of other connectors in the family, and is pressed in with the same flat rock press-in tools.
