Connector Facilitates Transfer Speeds Up To 5.0 Gbits/s
The HSSDC2 connector is designed to facilitate data-transfer rates up to 5.0 Gbits/s. It employs a smaller form factor and plugs that are die cast with a stamped latch/ground spring. It additionally features an impedance-controlled pc board and seven high-speed contact pads.

The receptacles offer six chassis ground locations, six pc-board grounding/retention contacts, four grounding contacts for cable-to-plug, and a metal EMI/RFI shield. The plug and receptacle employ polarization and keying. The connector can accept cable between 22 and 30 AWG and employs an overmolded strain relief. Employing gold-over-nickel plating on signal contacts, it's designed for 250 mating cycles. Offering positive latching, the connector maintains 2.5-Gbit/s data rates up to 15 m.

Connector Targets Gigabit Interface Converter Product Line
A right-angle connector functions with the company's family of gigabit interface converters (GBICs). The GBIC connector is designed for high-speed networking applications, including Fibre Channel and Gigabit Ethernet. It also suits telecom applications, including metropolitan-area networks (MANs), wide-area networks (WANs), and central-office networking.

The GBIC connectors are available with a choice of 0.062- or 0.093-in. pc-board tail lengths. They feature a unique blind-mating alignment system that provides automatic sequencing of application or removal of ground, power, and signal corrections. This ensures reliable hot-swap operation. Also, they feature selective gold-plated contacts and an integral metal hold-down strap for protection against electrostatic discharge (ESD).

These GBIC connectors are electrically tested for continuity and proper mating sequencing. They fully adhere to GBIC specifications and are UL recognized and CSA certified. In 10,000-unit quantities, the connectors cost $2.75 each.

RF Connector Facilitates Efficient PC-Board Fixturing
The PressFit RF connector features a gold center pin engineered with small fins. Upon pressing the connector onto the board, the fins are firmly wedged into the mounting hole. The device uses existing footprints as opposed to comparable units requiring distinct footprints to accommodate the center pin and four posts.

According to the company, the connector fits applications where mechanical strength, high durability, reliability, and low VSWR are required. It also suits video applications, including professional video switchers, surveillance, and test equipment. The PressFit meets all industry mechanical, electrical, and environmental standards.

In 10,000-unit quantities, the connector costs $0.39 each.
