PRECISION RF ROTARY JOINTS


API Technologies offers a standard line of Rotary Joints, formerly manufactured by Sage Labs, suitable for use in commercial and military applications. The term rotary joint describes a device used to transmit energy from a stationary RF line to a rotating RF line.

We offer designs with SMA, N, TNC and 2.92 connectors to cover a broad range of applications including:

  • Air traffic control
  • Ground-based, ship based and airborne radar
  • Image transmission
  • Telecommunication control data transmission

Our products are designed to meet MIL-E-5400 Class II.

All of our standard products are available from inventory at our distributor, A.E. Petsche d.b.a. CPN/Denelex Group.

Custom rotary joints available to meet your unique specifications.
