ERNI Elektroapparate GmbH is offering a complete connector portfolio for the Advanced Telecommunications Computing Architecture (AdvancedTCA) standard. To complement the ERmet ZD connector used for fast data transfer, the company launched the 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 from ERNI has been optimized for high-speed data transfer (Zone 2). Zone 2 can accommodate up to five ZD connectors per subassembly for base fabric (GbE), extended fabric (the actual switched fabric interface), update channel and timing clocks (synchronization).

The ATCA 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 within the socket 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. The press-fit zones are flat-rock compatible, which negates the need for special press-in tools. The special design fully protects against any risk of damage while pressing-in the connector.

The stamped female contacts' lead-in design, combined with contact cavity protection, prevents from contact stubbing. The post-plated contacts have no bare edges for long-term use in critical environments. A mounting screw (customer supplied) may be used, but is not required.

The ATCA power connector meets the PICMG 3.0 performance requirements, is fully intermateable with alternative connectors designed to the same standard, and is RoHS-compliant.
