Ordering / RFQ notes

  • Confirm exact ordering code, coil voltage, contact form and termination style before purchase.
  • Share load voltage/current, load type, duty cycle, ambient temperature and isolation requirement in RFQ.
  • Use the linked PDF datasheet for package drawing, dimensions and final rating limits.
  • For mercury wetted relays, confirm required mounting orientation, mercury-related compliance and disposal rules for the target market.
  • Product family context: Mercury Wetted Relay.
Engineering selection notes

Avoid common specification mistakes

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.

Typical applications

  • Precision test systems
  • Pulse and timing circuits
  • Instrumentation switching
  • Industrial measurement equipment

What to confirm before purchase

  • Voltage, current, load type and safety margin
  • Contact form, coil voltage and drive circuit
  • Mounting, wiring, environmental and compliance requirements
  • Sample validation quantity and production forecast
