High insulation resistance reed relays are designed for ultra-low leakage current performance, making them ideal for precision applications where signal integrity and isolation are critical. Engineered with specialized materials, extended creepage distances, and optimized internal geometry, these relays achieve insulation resistance levels up to 100 tera-ohms (TΩ) and in some cases, even 1,000 TΩ resulting in leakage currents in the picoampere range or lower.
These relays are available in configurations that support switching voltages up to 1,000 VDC and breakdown voltages up to 4,500 VDC, with custom options reaching 10,000 VDC switching and 15,000 VDC breakdown. Their high isolation and dielectric strength make them ideal for automated test equipment (ATE), semiconductor testing, and precision measurement systems where even the smallest leakage can impact results.
Compact, reliable, and built for demanding environments, High Insulation Resistance reed relays offer unmatched performance in high-voltage, low-leakage applications.
