R43A Series High Voltage Relay

R43A Series High Voltage Relay

The R43A series high voltage relay is engineered to meet demanding load conditions in high-voltage applications, while maintaining a compact structure. Its extended and layered ceramic body provides higher isolation compared to the R41A series, making it a safer choice for systems requiring enhanced insulation.

Thanks to its RF-compatible design, the R43A performs exceptionally well in high-frequency and precision switching applications. Its tungsten contact structure offers excellent make/break switching capability, ensuring long service life and stable operation. It is commonly used in applications such as antenna tuning units (ATUs) and high-voltage test systems.

The relay operates in an SPST-NO (Single Pole Single Throw – Normally Open) configuration. In this setup, the circuit remains open until coil power is applied. Once energized, the contact closes and connects the load. This simple yet effective configuration provides a reliable solution for isolation and safe control.
