Series D, Series HV
High Voltage Reed Relays
The Series D Relays are PCB mount Hi
• Normally Open or
Normally Closed Contacts
Voltage Relays capable of switching up to
8kV (dc or ac Peak). They have a dielec-
tric strength of 10kV. The DAR Series has
very low contact resistance, useful in min-
imizing errors in instrumentation systems.
• PCB or Panel
Mount Packages
The Series HV Relays are panel mount
High Voltage Reed Relays capable of
switching 10kV (dc or ac Peak) with a
dielectric strength of 12.5kV. They are
all available Normally Open or Normally
Closed and have a life expectancy of
millions of operations.
