R81C Series High Voltage Relay

R81C Series High Voltage Relay

The R81C series high voltage relay is designed to meet demanding load switching requirements with its compact form factor. Moreover, thanks to its high dielectric encapsulation, it provides superior insulation against external environments. Additionally, its RF-compatible design offers precise switching and reliable isolation in applications up to 7kV. As a result, this ensures high performance especially in systems requiring high frequency and sensitivity.

Equipped with tungsten contacts, the R81C series delivers advanced make/break capabilities. It can continuously carry currents up to 10A. Therefore, thanks to these features, many users prefer it in applications like antenna tuning units (ATU) and high voltage testing equipment.

Furthermore, it has an SPDT (Single Pole Double Throw) configuration, meaning the relay contains both Normally Open (NO) and Normally Closed (NC) contacts in a single structure. When the coil is energized or de-energized, continuity switches between these two contacts. This design consequently provides flexibility in system design and allows easy adaptation to different operating scenarios.
