SB50 & Contacts (1 set)
x1 SB50 Anderson Power housing
x2 SB50 Anderson Powerpole contacts
SB Series Powerpole connectors are available in a wide range of gauge contact options. It is important that the correct gauge option is chosen to match your cable selection. All gauges shown throughout the Powerwerx website are American Wire Gauge (AWG).
Powerpole connectors are both genderless and polarized connectors
Powerpole connectors are genderless, meaning the supply and load connectors are the same. Since there are no male or female parts, all Powerpole connectors mate with themselves.
Powerpole connectors are polarized, meaning the design is unique to prevent accidental reverse polarity connection. Only the positive (+) can be connected to positive (+) and negative (-) can be connected to negative (-). Connections can be quickly made and remade sightlessly or in the dark.
High current rating, low resistance
The size of the wire a Powerpole contact will accept is the primary limitation of their ability to carry a load. Powerpole connectors will safely handle higher loads or surges, please read the linked data sheets (PDF) for additional information.
The contacts are made of highly conductive silver-plated copper for minimal contact resistance at high currents. The average contact resistance is 500 micro-ohms.
Flat wiping contact system
This system allows for minimal contact resistance at high current. The self-wiping action cleans contact surfaces during connection/disconnection. The contacts are rated at 10,000 no-load connect/disconnect cycles. When two pairs are mated together, it takes approximately 15 pounds of tension to pull them apart.
Stainless steel spring
Good connectors should not lose contact tension under use or vibration. Powerpole connectors use a stainless steel spring which applies 50 lbs. of pressure to hold the silver-plated copper contacts firmly together and maintain constant contact. This is ideal for frequent connect/disconnect cycles. Other cheaper connectors simply depend upon soft copper that eventually spreads apart and becomes loose.
Durable polycarbonate housing
The Powerpole insulated housings use a durable, high impact-resistant, high temperature polycarbonate plastic with a UL94 V-0 flammability rating. The connector design allows air to flow through the housing, assisting in cooling.
