Erni now offers a complete connector portfolio for the Advanced Telecommunications Computing Architecture (AdvancedTCA) standard. To complement its well-established ERmet ZD connector, used for fast data transfer, it offers a new ATCA Power Connector, designated for use in Zone 1 as specified by PICMG 3.0.
The AdvancedTCA (PICMG 3.0) standard defines connectors for three functional zones: power supply and system management (Zone 1); data fabric, update channels and timing clocks (Zone 2); and backplane rear I/O (Zone 3).
The ERmet ZD connector has been optimised for high-speed data transfer (Zone 2). Zone 2 can accommodate up to five ZD connectors per subassembly for base fabric (Gigabit Ethernet), extended fabric (the actual switched fabric interface), update channel and timing clocks (synchronisation).
This power connector is comprised of eight size 16 contacts and 22 size 22 contacts. It uses gold over nickel plating at contact interface, and tin plating on PCB terminals. The controlled thickness of plating at contact interface points ensures high reliability and performance.
The insulation body has an integrated guiding feature, and, based on reliable long-term field experience, the contact terminals provide compliant press-fit zones for easy assembly to a PCB. Being flat-rock compatible, there is no need for special press-in tools. The stamped female contacts' lead-in design, combined with contact cavity protection, prevents contact stubbing. A mounting screw may be used, but is not required.
The ATCA Power Connector is fully intermateable with alternative connectors designed to the PICMG 3.0 standard, and is RoHS-compliant.
