LI Series Reed Relay

The LI Series is a high-voltage, high-insulation reed relay designed for precision switching in applications requiring elevated isolation and ultra-low leakage. Epoxy encapsulated for durability, the LI Series achieves insulation resistance greater than 10¹³ Ω, making it ideal for sensitive test systems and high-voltage control environments.

Capable of switching up to 1,000 VDC, with breakdown voltages up to 4.5 kVDC and isolation voltages up to 7 kVDC, the LI Series supports SPST-NO (Form A) contact configurations and coil voltages of 5 VDC, 12 VDC, and 24 VDC. Rated for up to 100 W and 1.0 A, it is UL approved and available in through-hole mounting formats for secure PCB integration.
