Speedy supply for MIL-C connectors
In2Connect now offers "stock to build" on a 7/10 day basis for many popular MIL-C connector types and styles from Array Connector Corp of the USA.
They are classic, reliable two-piece pin and socket connectors that offer a full range of configurations to meet CompactPCI applications.
The ept hm 2mm is a gastight, high-density pin-and-socket connector which meets the IEC1076 international standard.
Its low inductance and controlled impedance make it ideal for PCI signalling.
The connector has 47 rows with 5 pins per row giving a total of 220 pins (15 pins are lost to the keying area).
An additional external metal shield is also provided.
The large number of ground pins ensures adequate shielding and grounding for low ground bounce and reliable operation in noisy environments.
The connector's controlled impedance minimises unwanted signal reflections and enables CompactPCI systems to have eight slots, as compared with the desktop PC's typical four.
With CompactPCI PCBs can be exchanged without problems from system to system.
Important parameters like fixing, shielding and coding remain compatible to all applications.
ept offers different types with inverted mating configuration.
The male connector is a fixed module at the backplane and the female connector is a free component of the plug-in module.
The male connector has five signal rows and two shielding rows.
A male connector version with eight signal and two shielding rows is also available.
The outer shielding rows 'z' and 'f' of the male connector engage the shielding contacts of the female connector.
The shield is also designed for gas tight, press-fit installation.
The six basic ept hm 2mm connector types can be assembled end-to-end in any order to cover most eventualities.
The connectors are designed to "nest" with each other, which provides additional support for the sidewalls when fitted in longer runs.
The connector system offers 15 press-fit contact lengths.
Within the 15 contact lengths are three mating levels, achievable on both the plug-in and rear I/O side.
Press-fit contacts avoid exposing high-layer-count PCBs to the thermal stress of soldering.
