Relays
As the original designer and manufacturer of the vacuum relay and later the vacuum diaphram relay, Jennings has been a world leader in the development of vacuum components. Vacuum relays produced by Jennings are designed to the highest quality and reliability standards, equivalent to those found in standard Mil-Spec ratings, and in fact many of Jennings relays are fully Mil-Spec rated. The reliability of Jennings vacuum relays is second to none; many of these relays have guaranteed life ratings set in the multi-million cycle range. The relays' reliability coupled with their small size and high power handling characteristics make the use of Jennings relays in any mission critical application an obvious choice.
Common applications include:
Vapor deposition etch equipment for semiconductor fabrication.
RF broadcast transmitters for radio and TV.
Satellite communications and deep space applications.
Medical, MRI and heart defibrillators.
Airborne and mobile communications.
Jennings relays feature:
Long life, high reliability.
Low contact resistance.
High voltage and current carry capabilities.
High speed switching.
Compact design.
SPST Vacuum Relays (up to 33 kV)
SPDT Vacuum Relays (up to 30 kV)
Gas Filled Relays (up to 70 kV)
DPDT Vaccum Relays
Coaxial Relays
The high dielectric strength of a vacuum is one of the important features which distinguishes Jennings vacuum coaxial relays from other types of coaxial relays. The use of vacuum as a contact environment increases the operating reliability and the life of the relay. Absence of oxygen prevents contact corrosion and the formation of oxides and organic materials, which can increase circuit resistance. Jennings vacuum relays are distinguished by very low thermal and RF noise generation. Because the contact resistance of vacuum coaxial relays is very low and stable, these units offer very low circuit losses. RF insertion loss is typically between 0.02 and 0.1 dB at operating frequencies.
Some of our most common applications are:
High speed antennae switching.
Transmit-receive switching.
Crossbar matrices.
CCTV, CATV.
Microwave telemetry data acquisition links.
Coaxial instrumentation.
Jennings coaxial relays feature:
Long life, high reliability.
High speed switching.
Low, stable contact resistance.
Maintenance free operation.
Compact size for applications with space/weight limitations.
Application flexibility.
