ICROMINIATURE Ideally suited to the needs of Automated Test Equipment and RF requirements. The specification tables allow you to select the appropriate relay for your particular application. Slightly larger than the 2200 Series; these relays provide maximum versatility with options such as electrostatic and coaxial shielding. If your requirements differ, please consult your local representative or Coto’s Factory.
