YP Series Circular Connector

  1. This series combines the advantages and functions of the Y2 series with the P-type electrical connector.
  2. The bayonet type connection structure with Y2 adopts the contact arrangement pattern of the P-type connector.
  3. It has the characteristics of small size, light weight, wide contact type spectrum and fast separation.
  4. The LYP series housing is machined from high-strength aluminum alloy.
  5. The LYP series is interchangeable with the YP series and is an ideal replacement for the old-fashioned ‘P’ connector.
  6. Widely applicable to electrical equipment and circuit connections between various instruments and meters
  7. Enterprise Standard: Q/321202LHY021-2012
