Backplane / VITA

There are two module sizes that provide application flexibility. Four-position modules (VITA 67.1) are intended for 3U VPX, in slots P2/J2. Suited for 6U systems, the eight-position modules (VITA 67.2) are to be used in slots P5/J5 or P6/J6

Precision machined from either stainless steel or aluminum, the 4 and 8 position housings are available with pre-loaded SMPM adapters or a cost effective, direct snap-in, cable mount SMPM contact. The right angle daughter card modules are offered with the direct snap-in SMPM contacts designed for both .047” and .086” flexible semi-rigid cable. To conform to the standard, the daughter card modules are right angled, and the Motherboard modules are vertical. Both are typically cable terminated.
