Ultra HV switching
HVR 20kV variants for high-voltage measurement, charging/discharging and routing.
20kV Reed Relay
20kV ultra high-voltage reed relays
20kV reed relays support high-voltage test and instrumentation designs that need compact isolation with careful creepage, clearance and leakage control.
Noise-aware designs
Shielded variants can help sensitive measurement and high-impedance circuits.
Samples + datasheets
Confirm load type, duty cycle and environmental requirements before production use.
