ER8 Series



ER8 Series, 0.8mm Pitch, High-Speed, Board-to-Board Connector


HIROSE has introduced the ER8 series of connectors that supports high-speed transmission of more than 10+Gbps for industrial applications.


Key Features


  • Number of contacts: 10, 20, 30, 40, 50, 60, 70, 80, 100, 120

  • Contact pitch: 0.8mm

  • Current rating: 0.5A

  • Stack height: 7mm – 12mmVoltage rating: 100V

  • Mating cycles: 100


Signal Integrity Features

The ER8 contacts are optimized for signal integrity performance to ensure reliable high-speed transmission performance.

The connector also features an excellent insertion loss-to-crosstalk ratio with a 5-aggressor differential far end crosstalk (FEXT) that meets the IEEE802.3ap specification for 10+Gbps and more.


Mechanical Features

The self aligning connectors have mating/unmating forces up to six times greater than typical micro pitch connectors. In addition, the ER8 series has an increased contact wipe and insertion depth, making them ideal for applications that require high-mating cycles and resistance to shock and vibration.



The ER8 series is available in parallel (mezzanine type) and right angle versions. The vertical connectors are offered with the number of contacts ranging from 10 to 120, while the right angle version is currently offered with 120 contacts. Featuring low profile stacking heights from 7mm to 12mm, the ER8 meets the size requirements of a wide range of applications.
