GF4A series self-plug high-speed sandwich connector
Introduction
  • The termination method is Press-Fit

  • 92Ω differential impedance

  • It is suitable for high-speed differential, low-speed and power transmission between parallel boards

  • Transmission rate: up to 56Gbps PAM4

  • Vibration resistance, impact resistance and zero-time delay design

  • The product has self-matching function

  • The contact is small with high density. The spacing between adjacent differential pairs in each column is 4mm (the spacing between signal contacts in the differential pair is 1.2mm, the spacing between adjacent signal contacts and ground contacts is 1.0mm), and the spacing between adjacent two columns is 2.5mm

  • The product adaptation height ranges from 14mm to 72mm, and can be applied to a variety of application scenarios
