Design Note

Vertical Installation (No Suffix): Ideal for high-density packing on the PCB where height is not restricted.
Flat Installation (-01): Ideal for card cages or applications with strict height restrictions.

Engineering selection guide

High Voltage Reed Relay selection details

Choose high-voltage reed relays by breakdown voltage, switching/carry current, contact form, coil voltage, insulation resistance, mounting style and high-voltage creepage constraints.
