2mm Hard Metric Press-Fit connectors

Connectors in the 'ept' hardmetric connector system, ept-hm 2.0 comply with IEC 61076-4-101 and are intermateable with all other similarly compliant products from other manufacturers like Harting, Erni, Hirose and Tyco, etc.

Developed for high speed telecom backplane and PC104 for embedded systems, the signal connector for CompactPCI hardware platform is a classic example for the use of hardmetric connectors. The 'hm' 2mm is a gas tight, high density pin-and-socket connector which meets the IEC-61076 international standard. These connectors are now being used more and more in the computer / peripheral market as well as the industrial and instrumentation markets. Important parameters such as the fixing, shielding and coding of the printed circuit boards are compatible regardless of the individual application.

'ept' offers 5 row and 8 row 2.0mm hard metric connectors according to IEC 61076-4-101.

The product family includes all standard types and variants for CompactPCI, Hot Swap and CTI (Computer Telephony Integration). The modules are defined as the 5+2 row types A, B, AB and C and the 8+2 row types D, E and DE.

11.25mm contacts for shielding rows z & f

The grid

ept hm 2.0 connectors can be easily connected in series to form a continuous 2 mm grid. This grid pattern is advantageous when creating a printed circuit board since no space is lost in the individual connector modules.

Connecting modules

The ends of the insulator material are chamfered to simplify the connection of additional modules and avoid twisting the connectors. The chamfers ensure exact positioning on the printed circuit boards and stabilize the modules.

Coding

The connectors must be coded in a modern BUS system to avoid mixing up the printed circuit boards. "Coding keys" can be manually snapped onto the multi-function block of the connector types A, D, L and M. The different inserts are colour-coded and can thus be kept apart.

Multi-function block

The modules A, D, L and M are equipped with a multi-function block. This in turn can be equipped with the coding keys. The moulded guides ensure the correct alignment of the male and female connectors to each other and they offer anti-twist protection before contacting. The coding keys can be inserted or withdrawn using a simple insertion or withdrawal tool.

Contact lengths of the mating and termination side

ept offers three different lengths for the front and four different lengths for the rear side. The different contact lengths are necessary because certain signal or ground contacts need to be the first to be connected/disconnected when adding/removing a module. The 11.25 mm long contacts are mainly required for the shielding rows z and f.
