Series Features
H Series Reed Relay
Series DescriptionThe H Series is a high-voltage reed relay designed 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 H Series is ideal for use in medical, industrial, and test environments where safety and reliability are paramount.
This relay features a specially packaged coil with PCB pin-out for the coil, while the switch contacts are configured for direct wiring (sky wiring), allowing flexible integration into high-voltage systems. Available in SPST-NO (Form A) and SPST-NC (Form B) contact forms, the H Series supports coil voltages of 12 VDC and 24 VDC, and is rated for up to 50 W and 3 A. It is a proven replacement for mercury wetted relays in applications requiring clean switching and long-term reliability.
