Series Features
HI Series Reed Relay
Series DescriptionThe HI Series is a high-voltage, high-insulation reed relay designed for ultra-low leakage and precision switching in demanding environments. Engineered with extended creepage distances and specialized materials, the HI Series achieves insulation resistance greater than 10¹⁴ Ω, making it ideal for applications requiring picoamp-level leakage currents and high dielectric strength.
Available in SPST-NO (Form A) contact configurations, the HI Series supports coil voltages of 5 VDC and 12 VDC, and is rated for up to 100 W, 1000 VDC, and 1.0 A. Its open-frame design and high leakage distance ensure safe operation in high-voltage systems, while through-hole mounting provides secure PCB integration. The HI Series is a trusted solution for test and measurement, control systems, and medical equipment requiring high isolation and reliability.
