Environment Resistant Connectors (Heat Resistance / Vacuum Characteristics)


  • High performance, heat resistant type can be used in severe conditions up to 250°C, a feature that other series can't match.
  • Hermetically sealing vacuum (airtight) type connector seals the solder surface and coupling surface with epoxy resin.
  • The secure push & pull type latching system allows for smooth and easy insertion / removal of connectors.
  • Can be used to wire cables easily without dedicated tools as it is solder joined.
