HE Series Reed Relay
The HE Series is a high-voltage reed relay engineered for precision switching in demanding applications requiring elevated isolation and breakdown performance. Capable of switching up to 10,000 VDC and withstanding breakdown voltages up to 15,000 VDC, the HE Series is ideal for use in medical, test & measurement, and industrial systems where safety and reliability are critical.
Encapsulated in epoxy for durability, the HE Series offers multiple PCB pin configurations and optional high-voltage wire leads for direct wiring. Available in SPST-NO (Form A), SPST-NC (Form B), and DPST-NO (Form 2A) contact forms, it supports coil voltages of 5 VDC, 12 VDC, and 24 VDC, with rated power up to 50 W and current handling up to 3 A. With leakage distances exceeding 26 mm, the HE Series is a trusted replacement for mercury wetted relays in high-voltage environments.
