ERmet ZD High-Speed male backplane signal connectors designed for high-speed differential signalling in telecom applications at data rates of up to 5 Gbits/s. These ERmet ZD high-speed signal connectors have an optimised grid construction designed to reduce signal interference and improve RF characteristics. This grid layout also enables these ERmet ZD connectors to be integrated with conventional 2 mm HM or Eurocard connector systems (IEC 061076-4-101). The ERmet ZD connector has 3 connection levels to ensure reliable mating and ground shield and signal pins that mate sequentially at 1.5 mm intervals. Each pair of signal pins has an ’L’ shaped shield blade surrounding them which provides internal differential shielding. This shielding enables the connector to maintain high performance levels when faced with reflections and cross. The ’L’ shaped shields also offer protection to the signal contacts against damage caused by stubbing. The contacts of these ERmet ZD backplane high-speed signal connectors have a low noise, dual beam design. The inline layout of the signal and ground contacts allows easy and economical trace routing to be achieved. Press fit terminations allow simple and secure PCB mounting.
These ERmet ZD female connectors are 25 mm in length and are available in 2, 3 & 4 pair configurations.

The ERmet ZD range of connectors have been selected as the backplane interconnect for the PICMG 3.x (ATCA) industry standard and meet performance requirements of high speed, low voltage differential signalling. These ERmet ZD header connectors are suitable for use in backplane and high-speed applications in the telecommunications and computer industries. The two pair ERmet ZD header can also be combined with applications that use ERmet 5+2 connectors due to the shared width of 15.4 mm. The three pair ERmet ZD header connector is ideal for Eurocard backplane designs with a 2 mm card spacing. The The four pair ERmet ZD header can also be used in board-to-Board, Mezzanine and AdvancedTCA applications.
