Revision 3.0 of the Compact PCI core specification comprises hot swap and computer telephony specifications such as pin sequencing. For Compact PCI, Erni's metric ERmet connectors are specified in accordance with IEC 61076-4-101 which are available in types A, B, AB and as monoblock versions. This new version of the CompactPCI specification has the consequence that for 3 HE backplanes on position P2 a male connector, type B with long connection pins for AB transfer and AB shrouds are inserted into position rP2.
At the rear card end, on position rJ2, a shielded female connector type AB is specified. For 6 HE backplanes, on P3 and P5, the male connector - type B with long connection pins - for AB transfer and AB shrouds have to be inserted in position rP3 and rP5. At the rear card end, on positions rJ3 and rJ5, a shielded female connector, type AB, has been specified. On P4, a blade contact strip, type A with long connection pins for A shroud and A shroud frames, has been specified on position rP4.
For the rear card end, a shielded connector type A, has been defined on rJ4. For male connectors with shrouds in types A and B, the specification requires a series grounding for the upper screening panel.
All necessary connectors required in accordance with the new CompactPCI specification are available from ERNI. In addition, for CompactPCI applications, ERNI also offers an economic solution for a male connector with long terminal pins, which is populated with shield contacts on row a only. In addition to the new AB compatible male connectors for CompactPCI, ERNI also supplies shrouds. Here, all shrouds are available in four different heights (3,9 mm, 4,5 mm, 5,3 mm and 6,1 mm) in order to adapt to the PCB thickness of the backplanes.

A cordless ESD (Electrostatic Discharge) wrist strap does not work by grounding the person in the same way as a traditional wired wrist strap. Instead, it works by reducing or balancing the static charge on your body so that you are less likely to discharge electricity into sensitive electronic components.
