Hirose Electric


Hirose has introduced a miniature board-to-board connector which features a rugged design and supports high data-transmission speeds of more than 10Gbits/s. This combination makes the new ER8 series ideal for use in industrial applications such as servomotors, servo-amps, AC drives and electric measuring instruments.

The ER8 is a licensed second source for the Samtec Edge Rate® series of connectors.

With a pitch of only 0.8mm, the ER8 series’ contacts are optimized for signal integrity, ensuring reliable high-speed performance. The ER8 connectors offer a wide self-alignment range and a lower mating force than competing micro-pitch connectors while maintaining higher extraction forces. In addition, the ER8 series connectors have an increased contact wipe and insertion depth, making them ideal for industrial applications that require a high number of mating cycles and good 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 ten to 120 positions, while the right-angle model is offered with a 120-position pin count. Featuring vertical stacking heights from 7mm to 12mm, the ER8 meets the size requirements of the latest generation of industrial equipment.
