General information about MCH Plug Connectors
An important component of a MicroTCA™ system is the
“MicroTCA™ Carrier Hub”, abbreviated MCH. The main
functions of an MCH module are hardware platform
management and the management of the fabric
connectivity. Since the MCH module requires many
more connections than a standard AdvancedMC™
module, an MCH may have up to 4 mating tongues
each with 170 contacts.
The MTCA.0 specification recommends the use
of a special Plug Connector to reduce the insertion
force of the module and to solve the tolerance stack-
up problem between the multiple tongues and the
backplane connectors.
The HARTING Plug Connector system consists of
three different Plug Connectors. The AdvancedMC™
Plug is required for an MCH module and is always
used in the MCH1-slot. Furthermore it can be used for
any conventional AdvancedMC™ module to replace
the pcb gold pads.
AdvancedMC™ Plug, MCH Plug, Piggyback Plug
If more than one mating tongue is needed, the MCH
Plug Connector is mated with the backplane MCH
connectors 2 and 3 depending on the MicroTCA™
MCH stacks in basic side version with 2, 3 and 4 tongues
configuration. Compared to the AdvancedMC™ Plug,
the MCH Plug insulator has standoffs ensuring the
correct distance for the slot width between two tongues
or backplane connectors respectively. The MCH and
AdvancedMC™ Plugs have different contact staggering
on the basic side, the extended side is equal.
The Piggyback Plug Connector is designed for the
MCH4 slot, but the connector itself is soldered on
the PCB3. For a MicroTCA™ system with more than
6 AdvancedMC™ modules using the switched fabric
fat pipe, an MCH module with 4 mating tongues must
be used. In general the switched fabric is located only
on the PCB3, so a high-speed connection is needed
between the MCH4 slot and the PCB3.
To build a connector stack for two, three or four mating
tongues, the HARTING Plug Connectors are mounted
like building blocks via pegs and the holes on the
adjacent Plugs. For additional mechanical stability,
the connector stack is fixed using metal stacking pins.
The complete connector stack can be installed easily
without any special tooling.

Piggyback Plug
As with the AdvancedMC™ Plug, HARTING offers the
Plug Connectors for MCH modules in versions for basic
side or extended side mounting. Only connectors with
the same mounting direction can be stacked together.
The Piggyback Plug is only available as basic side
version, therefore for a MCH module with four tongues,
the basic side version is preferred.
