Vacuum relay is shielded for longer life
Gigavac's new G18 is the only relay of its kind in the industry that is fully RoHS compliant - and has an internal shield for increased life.
According to Jim Lanum, Vice President of Sales and 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 vaporise, and the material becomes deposited and plate-out the internal walls of the ceramic envelope"

HV relay copes with high inrush currents
New from high-voltage-relay specialist Gigavac, the G13 is a completely sealed DPDT (double pole double throw) 15kV relay.
Latching high voltage relays make sense
Gigavac has created ten new latching high voltage relays that are completely sealed and rated from 8 to 70kV.
"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 10kV at 2A for 100,000 cycles, 330V DC at 17A 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 - 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 inrush current "make" applications.
According to Lanum: "Our new G18 fills out our line of single pole double throw (SPDT) 15kV 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, 26.5 and 115V DC, or customised.
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 US $387 each for five pieces, US $253 each for 50 pieces, and is in stock for immediate delivery. Request a free brochure from Gigavac ...
