The Standard IEC 61076-4-101 The hardmetric connector system ept hm2.0 was developed and manufactured according to the international standard IEC 61076-4-101. Thus the user can rely on a worldwide standard for the connection of printed circuit boards using connectors with a large number of contacts. The printed circuit boards can be exchanged between systems without difficulty. Important parameters such as the fixing, shielding and coding of the printed circuit boards are compatible regardless of the individual application. ept hm2.0 connectors are designed with a 2 mm metric grid. They can be...

System Modularity ept hm2.0 modules offer a number of possibilities to optimize large contact densities, especially in combination with coaxial or fiber-optic connections. Anzahl Kontakte: Number of contacts: 110 Using module type A, connections with a length of 50 mm can be set up in increments of 25 mm to achieve an overall length as required. The connectors with a multifunction block (types A, M, L) are preferably arranged at the beginning of a connector row. The type B module on the other hand is only arranged between other modules. Due to their inverse-polarity protection the 25 mm type...

hm2.0 Overview CompactPCI Connectors Overview CompactPCI Connectors CompactPCI as the PICMG standard places high requirements on 19-inch high-end systems with passive backplanes as regards robustness, reliability, and performance. CompactPCI platforms are cost optimized, scalable, suitable for harsh environmental conditions, and highly durable. This is why system designers rely on robust, modular, standard-compliant CompactPCI platforms. The PICMG® standards for CompactPCI provide specifications for hard metric connectors. ept’s hm2.0 connectors are optimally suited for use in CompactPCI applications....

Electrical Characteristics The connector system ept hm2.0 has been especially developed for high data rates. Below some HF characteristics are described as example. A SPICE model is available for simulation when developing systems. The simulation model was verified by means of TDR measurements.

Cross Talk ‘Crosstalk’ means that independent signal channels are influencing each other in an unwanted manner. This effect is expressed in decibels. Near end and far end cross talk was measured and simulated for different arrangements. A 200 mV input signal and a signal rise time of 25 psec. were applied. Cross talk from a pin in row d to an adjacent pin in row d (from C to G) Near end Measured cross talk, near end Simulated cross talk, near end Background noise Measured cross talk, far end Simulated cross talk, far end Cross talk from a pin in row d to a diagonally positioned pin in row e (from...
