FCI Metral® 4000 Connectors

The FCI Metral® 4000 connector, FCI part number 52057-102, designates a 30-position, right angle connector used on the I/O controller board. The Metral® receptacle’s contact geometry is optimized to match 100Ω impedance for differential signal pairs. The Metral® 4000 insertion loss is less than 1.0dB at 5Gb/s. The corresponding connector at the backplane interface is a vertical Metral® header, FCI part number 59566-1001. The Metral® 4000 header features three levels of staggered pin lengths to provide sequential mating of ground, power, and signals to facilitate hot-swap of controller boards. Metral® 4000 receptacles and headers feature press-fit tails for reliable attachment to circuit boards without soldering.

The press-fit section is designed for 0.6mm-diameter drilled holes, which provide additional room to route board traces and lower capacitance for via holes. The connectors are designed to conveniently stack end-to-end.

Features & Benefits:

  • Connector meets SATA serial data transmission rates of 1.5Gb/s
