GIGAVAC has solved the plate-out condition of vacuum relays by adding an internal shield to its G8 relay. The deposits hit the shield of the G18 rather than the ceramic wall, resulting in a relay life many times longer than relays without the shield.

GIGAVAC's G18 also has molybdenum and tungsten contacts, which means it can easily switch 2A at 10kV for 100,000 cycles, 17A at 330V for 10,000 cycles, or switch other currents at voltages up to 15kV. It is the only relay of its kind in the industry that is fully RoHS compliant. The G18 is the same size as GIGAVAC's G8 vacuum relay that is used for RF applications and lower current switching, as well as GIGAVAC's G2 vacuum relay with copper contacts for high current RF carry applications, and the G15 SF6 gas filled relay for high in-rush current "make" applications. The G18 fills out GIGAVAC's line of Single Pole Double Throw (SPDT) 15kV relays making it easy for you to select the smallest and best relay for your specific application. The G18 is available with coil voltages of 12VDC, 26.5VDC, and115 VDC, or customized. Plus they have GIGAVAC's exclusive changeable coil feature that allows users to change the coil even after the relay has been installed. Latching versions are also available.
