Small Size And Low Torque Of 2 Channels 18GHz High Frequency Rotary Joint Slip Rings
Description of HF0218-64 High Frequency Rotary Joint
The SenRing HF0218-64 series high-frequency rotary joint is a two-channel 18GHz high-frequency rotary joint with a frequency range of DC to 18GHz. The joint type uses SMA-K/SMA-K and is designed for a maximum speed of 60 rotations per minute. HF0218-64 is developed based on HF0218-31 with an additional 24 electrical slip ring channels. It is a product specially developed to meet the transmission requirements of high-speed serial digital or analog signals (and requires transmission of 1 to 24 channels of current). The default current of this series of high-frequency rotary joints is 5A. If you need to increase the current path or change the current size, or need technical consultation, pre-sales consultation, or solution requests, please contact the SenRing technical team.
