DIMENSIONS

in Inches (Millimeters)

The CT128 and CS128 feature high current switching capability to 4.5A with a low

on resistance of 0.05Ω Maximum. Designed for ATE, Controls, or Measurement and

Instrumentation applications the CotoMOS® relay is capable of handling 40V load

conditions. If your requirements are different please contact your Coto Applications

Engineer for assistance through www.cotorelay.com or email us at
