According to Jim Lanum, Vice President of Sales & Technical Support for
GIGAVAC, "Customers tell us that one of the many reasons why they use our
vacuum relays is because they are the smallest in the industry with their
voltage rating. When power switching a load using a vacuum relay, even hard
contacts vaporize, and the material becomes deposited and plate-out the
internal walls of the ceramic envelope. Over time, these deposits reduce the
isolation voltage, which causes the relay’s end of useful life. GIGAVAC has
solved the plate-out condition by adding an internal shield to our G8 relay.
The deposits hit the shield of the new G18 rather than the ceramic wall,
resulting in a relay life many times longer than relays without the shield.”

GIGAVAC’s new G18 also has tungsten contacts, and it can easily switch 10
KV at 2 amps for 100,000 cycles, 330 VDC at 17 amps for 10,000 cycles, or switch other
currents at voltages up to
15 KV. It is the only relay of its kind in the industry that is fully
RoHS compliant—and has an internal shield for increased life. 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.
According to Lanum, “Our
new G18 fills out our line of Single Pole Double Throw (SPDT) 15 KV relays
making it easy for customers to select the smallest and best relay for their
specific application.” The G18 is available with coil voltages of 12 VDC,
26.5 VDC, and 115 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.
The G18 sells for $387 each for 5 pieces, $253 each for 50 pieces, and is
in stock for immediate delivery. GIGAVAC accepts all major credit cards and
generally ships the same day an order is received. Representatives
throughout the world can deliver the products in the user's country and
currency at the lowest possible cost. For complete information and ordering,
