The europacPRO family of subracks from electronics packaging specialist Schroff are designed to serve as versatile general-purpose enclosures for 19in. equipment and can also be configured for specific bus-based systems such as CompactPCI and VME64x.

The subracks' extruded-aluminium horizontal rails are available in either lightweight or heavy-duty versions, with the front rails featuring a long lip to allow the insertion and removal of CompactPCI or VME64x boards using IEEE 1101.10/11 and IEC 60297-3-103 extractor handles.

Subracks can also be supplied with optional, retrofittable EMC cover plates, front panels and contact strips to provide typical shielding levels of 40dB at 1GHz and 30dB at 2GHz.

The subracks are 84HP wide and come in a choice of 3U, 4U, 6U or 9U heights and six depths from 175 to 475mm.

All models in the range feature a robust aluminium construction and are resistant to shock and vibration in accordance with IEC 61587-2, EN 50155, SNCF standards NF F 67012/NF F 60002 and Deutsche Bundesbahn standards BN 411002/411003.

Schroff is also offering the Calmark Series 223 and 224 Card-Lok PCB retainers, which incorporate a patent-pending torque-limiting feature that enables a PCB assembly to be fixed into a chassis at a prescribed clamping force without the need for a torque wrench.

Primarily aimed at cold-plate heat-transfer applications within the defence and aerospace sector, these new five-wedge devices are designed to prevent damage to the PCB or to the Card-Lok itself due to over-tightening.
