Product family overview

HRM High Voltage Relay Modules application and selection guide

High voltage reed relays use hermetically sealed reed switches and insulation-optimized packaging for low-level, test and instrumentation switching where switching voltage, stand-off voltage and dielectric ratings must be checked separately.

Select this family when the design needs compact high-voltage switching, low leakage, clean signal isolation and repeatable switching in test or instrumentation systems.

Engineering selection notes

Before choosing a model

These notes keep product pages useful for engineers while avoiding overclaims. Final ratings remain model- and application-specific.

Separate switching, stand-off and dielectric ratingsSwitching voltage is the voltage the relay may open or close under specified load. Stand-off/hold-off and dielectric ratings are withstand tests and should not be treated as hot-switching capability.

Dry reed relays are low-bounce, not universally zero-bounceUse model datasheets for operate time and bounce behavior. Reserve bounce-free language for mercury wetted contacts or explicitly specified designs.

Load type controls lifeCapacitive inrush, inductive energy and hot-switching conditions can reduce contact life. Confirm load type, duty cycle and safety margin through datasheet review and RFQ.
