2.0 Connector System IEC 61076-4-101 Definition of Terms Contact length of the rear and front mating area Connector according to IEC 61076-4-101 ept offers 3 different lengths for the front mating area and 4 lengths The hardmetric connector system ept-hm 2.0 was developed for the rear mating area for the hm 2.0 male connectors. Different according to the international standard IEC 61076-4-101. As a contact lengths are required for signal and ground contacts to result, a worldwide standard for the combination of PCBs is establish first make and last break features. safeguarded by multicontact plug-and-socket connectors for The long contacts with 11,25 mm are predominantly used for the customers. shielding rows z and f. PCBs can be exchanged without problems from system to system. Important parameters like fixing, shielding and coding remain compatible to all applications. Thru hole specification of the PCB Throughplated holes for signal contacts and shieldings in press-fit techniques. The spacing The ept-hm 2.0 connectors have been developed with a spacing Hmole 0,6m of 2 mm between contacts. These connectors are modular and therefore can be stacked together without interrupting the 0,68-0,72mm Drillhole continuity of the 2 mm design. No space is wasted within a row of connectors. min.25m Cu Sn 5-15m Module stacking Platedthrough 0,55-0,65mm To improve stacking and to avoid accidental reversal of hole connectors the end of the housings engage the adjacent connector to insure exact positioning onto the PCB board and give the modules the necessary support. Derating Diagram A Coding In order to avoid accidental plug in among PC boards the IEC 3,5 loaded like a chess board 61076-4-101 standard provides protection through coding. Coding keys are easily hand inserted into the multifunction block of the 3 every 2nd row loaded connector module A, L and M. The pins are color coded for fast 2,5 visual recognition. fully loaded 2 1,5 Multifunction block 1 The modules A, L, M and compact PCI are equipped with a 0,5 multifunction block. The coding devices, according to the IEC standard, can be added to the multifunction block. The guides guaranty the correct mating and prohibit accidental reversal of 20 40 60 80 100 120 140 C the male and fermale connectors. Ambient Temperature C That coding devices may be assembled by a single plug and pulling tool and/or again removed. ept GmbH & Co.
