DHS064-25 RF rotary joints 64mm combination Dual-channel RF coaxial rotary joint and 25channels power signal.
RF rotary joint / RF Slip Ring:- DHS064 Series
Highly customized requirements, frequency DC-4.5, DC-18, 14-14.5GHz
DHS064-25 RF rotary joints are also called RF slip rings with out diameter 64mm combination Dual-channel RF coaxial rotary joint and 25channels power signal. RF slip rings are mainly used to transmit RF signals, high-definition signals, microwave signals, etc. The internal key material brushes must be made of highly elastic and wear-resistant materials, and the surface of the electric rings is treated with military-grade special electroplating to ensure the reliable transmission of high-frequency/RF signals.
RF rotary joint supports single-channel or multi-channel high-frequency signals, and can also be mixed with communication signals, control signals, gas-liquid media, power, etc. for transmission.
Product features
- Frequency: DC-18GHz DC-4.5Hz
- Hybrid power supply or signal transmission
- Low insertion loss, excellent standing wave ratio
- Support 2 RF channels
