RF Slip Ring
(Medium/High Frequency Slip Ring)
|
|
Description:
- Our RF slip
rings simulate coaxial cable structure, mainly
used for transmission of MHF (medium/high frequency)
signals, UHF (ultra high frequency) signals as well as electric power current and low frequency signals.
- The through hole can be realized at the axis center.
- All parameters
of MHF and UHF pass accurate analysis and
calculation to ensure the optimal comprehensive
performance result.
- Advanced
sealing structure is adopted between the MHF/UHF
signal channels with excellent insulation and
shielding capability.
- Superposition of electrical path along the axial direction, adopting gold to gold multi-points contact between with least resistance, reliable and endurable for long working life.
- Capable of
adapting to various environment such as high
temperature, low temperature, impacting,
vibration, salt spray, damp heat, water
saturation, and etc.
Features:
- Compact
structure with least space between channels.
- With RF
interface connection, convenient for
installation.
- With least
insertion loss and phase variation and highest
insulation.
- Strong anti-interference signal transmission with least loss.
- Strong
environment adaptation capability.
- Can be
integrated with current, low frequency, optical
fiber, liquid (gas) rotary joints
-
Maintenance-free during working life.
Typical Applications:
- Radar System.
- High Definition
Video Transmission.
- Satellite
Antenna.

Slip rings ensure engineering and design teams no longer require timely – and often costly – workarounds in order to power rotating devices, whether they be motors, military devices or rotating electrical assemblies. Playing a major role in improving mechanical performance, as well as simplifying operations, they have further further eliminated the threat of damaged and hazardous wiring and cable connections in moving joints.
Slip rings handle either power, data or both across a number of rings on which a spring or other loaded contact finger, ring or brush is held in place to pass power as the rings rotate.
Power levels range from milliwatts to hundreds of kilowatts dependent on application.
Our high-performance slip
rings are designed for use in a wide range of high-end OEM applications. We pride ourselves in our ability to provide the right solution for the right application
of slip rings. Our high-performance slip rings are designed for use in a wide range of high-end OEM applications.
