Powerpole® Connector Features & Benefits
  • Genderless Housings: Provide simplified assembly and minimize the number of components
  • Stackable Modular Housings: Available in four sizes to right size your connection need
  • Connection Versatility: Contacts for wire, PCB, or busbar all fit into the same housings
  • Low Resistance Connection: Silver or tin plated contacts inside housings that strongly force the contacts together
  • Color Coded Housings: Help ensure that connectors are assembled and mated correctly
  • Self Securing Design: Stainless steel springs create a robust force between the contacts that holds the connector in the mated condition, but allows it to be quickly disconnected.
