Hirose has developed a miniature board-to-board connector that combines a rugged design with high-speed transmission speeds of more than 10Gpbs to support a number of industrial applications. Featuring a pitch of only 0.8mm pitch, the ER8 Series contacts are optimised for signal integrity performance, ensuring reliable high-speed performance.

Now available through authorised distributors, the ER8 Series is a licensed second source for the Samtec Edge Rate Series, which is well-suited for servo motor, servo amps, AC drives, electric measuring instruments and other industrial applications.

The ER8 series offers a wide self-alignment range with reduced mating force while maintaining high extraction forces in comparison to typical micro pitch connectors. The rugged micro pitch connectors offer additional robustness when 'zippered' during mating/unmating.

In addition, the ER8 Series connectors have an increased contact wipe and insertion depth, making them ideal for industrial equipment that require high-mating cycles and resistance to shock and vibration.

The ER8 Series is available in parallel (mezzanine) and right angle versions. The vertical connectors are offered with pin counts ranging from 10 to 120 positions, while the right angle model is currently offered with a 120-position pin count. Featuring vertical stacking heights from 7mm to 12mm, the ER8 meets the size requirements of industrial equipment.

"As a second source with Samtec's Edge Rate Series, the ER8 Series board-to-board connector offers customers two dependable purchase sources," said Bill Kysiak, Product Marketing Manager for Hirose Electric USA. "We are excited to offer the ER8 Series interconnect solution through our authorised distribution partners worldwide."

"Hirose is a leader in high-speed and miniature interconnect systems, and this partnership provides customers a reliable second source for Edge Rate products," said Brian Vicich, Samtec's Vice President of Engineering.

The ER8 Series features an excellent insertion loss-to-crosstalk ratio with a 5-aggressor differential far end crosstalk (FEXT) that meets the IEEE802.3ap specification for 10Gbps with plenty of margins. The ER8 Series has a rated voltage of 100V AC, a current rating of 0.5A.

In addition to industrial equipment, the ER8 Series is commonly used in broadcast equipment, medical equipment, multifunction printers, point-of-sale equipment, vehicle navigation, and more.
