Coordination dimensions
and tolerances
The accompanying diagrams show the
depth dimensions used in the equip-
ment practice, used for both 2 and 2.5
[.079 and .098] systems, and allowable
tolerances for subrack and backplane
bending.
Coordination Dimension M
As defined in the DIN 43356 and IEEE
1301 Hard Metric equipment practices
for the 2.5mm system, and used in IEC
61076-4-101, the dimension M
range for free board engagement with
the backplane.
The specified contact mating must be
maintained on a mated pair of connectors,
within the range of M = 14 to 16.5 [.551
to .650] for the shortest mating level 1.
For mating levels 2 and 3 the contact
ranges are 14 to 18 [.551 to .709] and
14 to 19.5 [.551 to .768].
See page 67 for further details on
AMP Z-PACK 2mm HM contact mating
levels.
Misalignment and inclination
tolerances
Guiding and polarizing lugs of Type A,
M and L connectors, also at ends of
Type C and N, allow the mating
tolerances shown here.
Tolerances apply only when guide lugs
are separated by only one Type B
module without lugs.
