DC Connectors and Contacts

The SolarSpec™ DC Connectors from Molex provide a secure IP-67 sealed connection for series cabling of silicon photovoltaic (PV) panels through industry-standard pin and socket construction, easy 'snap-lock' mating, and an internal locking mechanism. The SolarSpec™ DC Connectors have Molex's exclusive design features including molded surface ribs for a secure grip, "touch-proof" safety construction to protect against an electrical current whether the connectors are mated or unmated, and a contact resistance of <0.5mΩ. The rugged design of the Molex SolarSpec™ DC Connectors meets NEC 2008 and NFPA 70; US-code for "the safe installation of electrical wiring and equipment" and the TÜV and UL dual-qualification for long-life in harsh conditions. The connectors are suitable for 14, and 12 to 10 AWG cable.

  • Simple 'snap-lock' mating for quick and easy factory
    or field assembly
  • Polarization and an audible 'click' ensure successful mating
    of the connectors
  • Internal locking mechanism protected by latch guards prevents accidental and unauthorized decoupling of connectors; ensures reliable connection and safe handling
  • "Touch-proof" safety design provides protection from electrical current even when connectors are unmated
  • IP67 sealing protection against dust and water
  • Resistant to UV and ozone damage
  • Dual-qualification by TÜV and UL; guarantees long-life in harsh environments
  • Exclusive moulded surface ribs allow for secure gripping, especially with work gloves
  • Contact resistance <0.5mΩ; lowest contact resistance compared with competitor products for greatest efficiency
  • Strain relief ensures strong, secure, enduring cable connections
  • Meets NEC 2008 and NFPA 70; US-code compliant for "The safe installation of electrical wiring and equipment"
  • Accommodates 14, and 12 to 10 AWG cable

Solar Junction Boxes and Cable Assemblies

Developed for the robotic assembly of silicon photovoltaic (PV) systems, the Molex SolarSpec™ Junction Boxes and Cable Assemblies simplify the panel-assembly production process and reduce manufacturing costs. The exclusively-designed spring terminals with optional Solder Charge Technology™ enable the SolarSpec™Junction Box Assembly to be attached to PV solar panels using robotic pick-and-place machines, which can reduce the assembly time by a factor of up to 10.

The SolarSpec™ cable assemblies are available for use in serial and parallel solar applications. The offering includes single-ended cordsets for use with solar junction boxes and double-ended configurations for array and field installations. The 12 AWG cables are double-insulated, electron beam cross-linked to ensure long life cycles and to meet the demands of harsh, outdoor solar applications. Molex SolarSpec™ cable assemblies are designed to connect to other products in the SolarSpec™ product line.
