Gigavac G81BB47 HV Relay
Gigavac G81B Series High Voltage Relay - 10kV / 10A
The **Gigavac G81B Series** is a high-performance Single Pole Single Throw (SPST) high-voltage relay, specifically engineered for precision switching and superior isolation in demanding electronic environments. Designed to handle peak voltages up to **10kV** and offering carry currents up to **10 Amps**, this vacuum-sealed relay ensures exceptionally low (0.03 Ohms) and stable contact resistance. With its fast 10ms operate/release time and a robust mechanical life of **2 million cycles**, the G81B series serves as a premier component for high-voltage power supplies, medical imaging, and RF communication systems where long-term reliability is paramount.
