Product family overview

Mercury Wetted Relay HGSR 8KV application and selection guide

Mercury wetted relays provide stable low contact resistance and extremely low or bounce-free switching behavior for specialized precision measurement and test applications where signal integrity is critical.

Use this family where bounce performance and contact stability are more important than a general-purpose relay solution. Confirm orientation, regulatory and application limits before production use.

Main parameters

Key selection parameters

Series: HGFR / HGMR / HGSR / HVR and related families
Switching behavior: Low bounce and stable contact resistance
Signal type: Precision signal, pulse and test switching
Orientation: Series-dependent; confirm mounting requirement by datasheet
Compliance note: Mercury handling/application suitability must be confirmed for the target market

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.

Orientation and compliance must be checkedMercury wetted relays are specialized precision parts. Many types require a defined mounting orientation and may be restricted by RoHS, WEEE, transport, disposal or customer environmental rules.

Bounce wording is contact-technology specificMercury wetted contacts are selected where extremely low or bounce-free switching is required. Do not apply this claim to dry reed relays unless an individual datasheet supports it.

Best fit: precision signal switchingUse mercury wetted types for low-level measurement, pulse/timing and data-acquisition circuits where contact stability is critical, not as a universal relay upgrade.
