8kV, 6A
An open frame RF reed relay with 8kV isolation and
6A (at 30MHz) carry current, the FRD12000 series
has been used many HF radio system specifications
over the years, with applications in commercial
maritime (GMDSS) equipment and military HF
radio units worldwide. The use of vacuum reed
switches with rhodium contacts offers high isolation
voltages, low contact resistance and long operating
lifetime.
Up to 8kVDC Isolation between Contacts
6A Carry Current (up to 30MHz)
Excellent RF Performance
Ideal for Antenna Tuning Units
Form A/B Contact Configuration
Customising Facility
Available as Form A (SPNO) or Form B (SPNC)
contact configurations.
