1. INTRODUCTION
This specification covers the requirements for the application of Z–PACK 2 mm HM Interconnection System for
Board–to–Board Connections and provides information on the standard modules (Types A, B, C, A/B, D, E, F,
and D/E) and modules with cavities for special contacts (Types L, M and N). Other parts of the Z–PACK 2 mm
program are mentioned for reference only, as these applications are described in other separate application
specifications. Refer to Paragraph 2.4.
The Z–PACK 2 mm HM Interconnection System is a two part connector system intended to connect free
boards (daughterboards, printed circuit (pc) boards) to a fixed board (motherboard, backplane or backpanel);
and to feed this connection through the fixed board. Also the connection of the free boards and the connection
of cables to pc boards allows for multiple configurations.
The Z–PACK 2 mm HM Interconnection System consist of the combinations shown in Figure 1.
1.1. Board-to-Board Connections
A. Free Board to Fixed Board Connections
1. Standard Connections
(a) Standard (= Right–Angle) Female Connector on the Free Board
(b) Standard (= Vertical) Male Connector on the Fixed Board
2. Midplane Connections
In a midplane connection, a free board can be connected to the rear side of the fixed board. This
connection is composed of the feed–through pins of the standard male connector and a shroud at the
rear side, with a spacer to fix the shroud to the feed–through pins.
B. Free Board to Free Board Connections
1. Card Extender Applications
(a) Right–Angle Male Connector
(b) Standard (= Right–Angle) Female Connector
2. Mezzanine and Baby Board Applications
(a) Standard (=Vertical) Male Connector
(b) Vertical Female Connector
1.2. Cable-to-Board Connections
A. Cable to Fixed Board Connection
This backpanel connection is composed of:
1. Feed Through Pins
Feed through pins of the standard male connector and a shroud at the rear side, with an integral
retention plate to fix the shroud to the feed through pins.
2. Cable Connector Female
B. Cable to Free Board Connection
This front connection is composed of:
1. Right–Angle Male Connector
2. Cable Connector Female

1.3. Components
All pc board connectors are connected to pc boards by miniaturized ACTION PIN* contacts. In order to meet
the signal requirements, connectors can be stacked along the edge of the pc board as specified in
Paragraph 3.4.
All complete pc board connectors are equipped with guide and polarization posts. Connectors are also
available with a Multi–Purpose Center (MPC) which can be used with a coding device as specified in
Paragraph 3.6. These alignment features can also be used to guide connectors (Types B and E) which do not
have any alignment features.
Thirteen different Types (styles) of connector modules are defined:
110 signal contacts, 50 mm length, with MPC, guiding and polarization
125 signal contacts, 50 mm length/110 44 mm/95 38 mm
55 signal contacts, 25 mm length, with guiding and polarization
125 signal contacts, 50 mm length with guide and polarization/110 44 mm /95 38 mm
6 cavities for special contacts, 50 mm length, with MPC, guiding and polarization
3 cavities for special contacts, 55 signal contacts, 50 mm length, with MPC, guiding and
polarization
S
Type N:
3 cavities for special contacts, 25 mm length, with guiding and polarization
S
Type M–MSC: 4 cavities for fiber–optic plugs, 55 signal contacts, 50 mm length with MPC, guiding and
polarization
S
Type L–MSC : 8 cavities for fiber–optic plugs, 50 mm length with MPC, guiding and polarization
S
Type D:
176 signal contacts, 50 mm length, with MPC, guiding and polarization/128 38 mm
S
Type E:
200 signal contacts, 50 mm length
S
Type F:
88 signal contacts, 25 mm length, with guiding and polarization
S
Type D/E:
200 signal contacts, 50 mm length with guide and polarization
Male connectors of Type A, B, C, A/B, and M have 5 rows of signal contacts, and D, E, F, and D/E have 8 rows
of signal contacts. Optionally they can have 2 additional rows for ground return. Female connectors of these
types always have 5 or 8 rows, a two–part ground return shield is also offered. Refer to Paragraph 3.7 or
Application Specification 114–19036 for ground return shield details.
Reduced–crosstalk shielding is based on signal transmission in wire–pairs. The shields are located between
the columns (chicklets) in the female connectors. The shielding between rows is accomplished by grounding
the entire row c. Reduced crosstalk shielding combined with ground return shields is applied mostly for
differential pairs. The special contact cavities used in Types L, N and M can be equipped with coax, power or
fiber–optic contacts, which must be separately ordered.
