4 Series
Screened. 3.5kV, 3.5A
Developed for RF applications (in the band 1-30MHz) the 4 series reed relay offers
a highly fexible, low cost package available with form A (NO),form B (NC) and
latching (bistable) contact configurations as well as switch connections for either
PCB or flying lead mounting. The use of Crydom’s vacuum reed switches with
rhodium contacts means that high isolation voltages, low contact resistance and
long operating lifetimes are achieved. Additionally, RF screening is available to
further enhance RF performance for more demanding applications.

5 Series
Fully Screened. 3.5kV, 4A
Developed closely with RF design Engineers in the radio communications
industry, this new fully screened reed relay series offers the ultimate in low RF
loss and current carrying capability. The relay coil section is totally enclosed in a
copper screen, resulting in lower self-heating and ESR. Together with Crydom’s
vacuum reed switches, benefits include higher carry currents for a given
frequency and ambient temperature. Peak RF isolation voltages up to 3.5kV are
achieved by clever coil design, maximising pin spacing. Switch connections are
offered for either PCB or Flying Lead mounting.

SIP Series
Reed Relay
The SIP series reed relays are available in both voltage and current driven (line sense) versions. The SIP
range requires only half the PCB area of the DIP series.
The construction of the SIP series corresponds to the creepage and clearance requirements of the new
European Standards; EN60950.

FRS12000 Series
Miniature Single RF Reed Relay
Offering outstanding RF performance for their size, the FRS12000 series can withstand RF voltages up to
3kV and carry RF currents of 6A at 30MHz. Utilising plastic and encapsulant materials with exceptional
RF and temperature characteristics, the FRS12000 Series RF Reed Relays feature in house manufactured
reedswitches, with copper plating and high vacuum much revered in the industry for their high power
performance and reliability.
Designed on a standard 0. 1" pin pitch (some variants available on 0.15"), the FRS12000 series can be
fully customised to your requirements, with options for open frame or encapsulated, magnetic screening,
coil voltages, and contact configuration. Crydom have also recently developed a 5kV version with contact
pins exiting the cover for flying lead connection. Contact Crydom for details.
Typical applications for the FRS12000 Series include antenna tuning units, as well as harmonic and co-site
filtering over the HF band.

FRD13000 Series
Fully Screened. 9kV, 6A
A development of the FRD12000 series, this design has a complete RF screen
around the coil assembly, offering a very low loss transmission path. This results
in better carry current performance at elevated temperatures. This device also
features an anti-corona sleeve shrouding the reed switch contact for improved
peak RF voltage isolation.

FRS22012
Fast Latching, Screened. 3.5kV, 1.5A
The FRS22012 latching RF reed relay designed for manpack portable
HF radio systems where power resources are limited. The relay is capable of
withstanding 3.5kV between contacts and carrying 1.5A current at 30MHz.
The device features RF and magnetic screening, allowing close mounting, and
a unique coil design enabling switching with coil pulse lengths down to 0.5ms,
further reducing power supply demands. The FRS22012 is an ideal choice for
applications where board space is at a premium but where RF performance
is demanded.

FRD30000 Series
Fully Screened. 6.5kV, 20A
This flagship relay series offered by Crydom employs multiple high vacuum reed
switch contacts ensuring excellent performance and reliability for high voltage
and heavy carry current applications. The two basic models, FRD32061 and
FRD32062 will carry currents of 12 and 20A respectively at 30MHz and feature
silver plated, fully screened coil assemblies for ultra-low RF losses. Typical
applications include over the horizon (OTH) HF radar systems and 1kW base
station transmitters.
