R43B Series High Voltage Relay
The R43B series high voltage relay is designed to withstand demanding load conditions in high voltage applications. It maintains a compact form factor, but its extended and layered ceramic body provides higher insulation compared to the R41A model. This feature offers additional safety for systems requiring enhanced insulation.
Thanks to its RF-compatible design, it delivers superior performance in applications requiring precise switching and reliable isolation. Equipped with tungsten contacts, it offers improved make/break performance, ensuring reliable and long-lasting operation. The R43B series high voltage relay is widely used in professional fields such as antenna tuning units (ATU) and high voltage testing systems.
It operates with an SPST-NC (Single Pole Single Throw – Normally Closed) configuration. This means the relay keeps the circuit closed until the coil receives power. Once energized, the coil causes the contacts to open and create isolation. This simple yet effective design ensures safe control and isolation in high voltage systems.
