HM Series Reed Relay
The HM Series is a high-voltage reed relay engineered for precision switching in extreme isolation environments. Capable of switching up to 10,000 VDC and withstanding breakdown voltages up to 15,000 VDC, the HM Series is ideal for applications requiring robust dielectric strength and minimal leakage, such as medical equipment, cable testing, and automated test systems.
Encapsulated in epoxy for durability and available in multiple PCB pin configurations, the HM Series offers flexible mounting options including through-hole and axial lead formats. It supports SPST-NO (Form A), SPST-NC (Form B), and latching (Form E) contact forms, with coil voltages of 5 VDC, 12 VDC, and 24 VDC. Rated for up to 50 W and 3 A, the HM Series also features leakage distances greater than 32 mm, making it a reliable replacement for mercury wetted relays in high-voltage applications.
