can be locked at up to 20 positions without the need for reinforcement ribs. In addition, the plastic locking
and latching profiles have compact geometries. For example, the overlap between the connector and
header fronts has a wedge shape that ensure a smooth guiding-in of the two halves during connector
mating. When fully mated, the overlap results in a strong, positive connection formed by two wedge
shapes securing each other.
8 | HOW NanoMQS TERMINALS DELIVER UP TO 50% SPACE REDUCTION
NanoMQS series terminals are designed for a nominal pitch, corresponding to the distance between
the pins connecting with the PCB of 1.8 millimeters. Therefore, the same number of positions on a
NanoMQS header requires only approximately half the space on a PCB compared to an MQS header
needs (Figure 6).
As depicted in the figure, the
header footprint of the MQS plat-
form is reduced from 840 mm

to
411 mm

with NanoMQS system.
Clearly, high-position intercon-
nections will be much in demand
with next-generation car architec-
tures with significant packaging
density. In an engine ECU Nano-
MQS terminals could save 60 per-
cent of the ECU's spatial footprint.
Current NanoMQS terminal ver-
sions can accommodate up to
320 positions. This makes the
NanoMQS platform ideally suited
for hybrid connectors, as every
contact of the MQS family can be
integrated into a grid as a multi-
ple of the next size up (Figure 7).
This capability is enabled by the
fact that the secondary locking
device is on the same level on all
housings.
