Solar Connector Kit 100 Pairs

This pack contains one hundred male and female connector pairs built for photovoltaic cable terminations. The 4.0 mm pin diameter suits 2.5 mm², 4 mm² and 6 mm² conductors, covering 14 AWG to 10 AWG wire sizes. Silver-plated copper contacts provide low resistance connections for DC solar circuits.

Build Integration 4.0 mm Pin

Mated connectors achieve IP67 protection against dust and water ingress, while unmated halves meet IP2X finger-safe rating. The PPO and ABS housing with PC/PA insulation operates from -40 °C to +90 °C and meets UL94-V0 or UL94-5VA flame classification. Each pair requires standard crimping tools and compatible cable; no additional sealing parts are included.

Installer Fit and Limits

Suits installers assembling or repairing string-level DC wiring on residential or commercial arrays who need bulk quantities of 4 mm format connectors. Not for buyers requiring 3 mm or 5 mm pin formats, AC-rated plugs, or pre-assembled cable leads. The 30 A rating at 4 mm² and 6 mm² covers typical module strings; higher current trunk runs need larger contacts.

Questions about this item

What is the maximum continuous current the 4.0 mm contacts can carry before they overheat?

The 4.0 mm contacts are rated for 30 A continuous current at the specified temperature range.

Do these connectors run hot or make noise when left in full sun all day?

They are passive components with no moving parts, so they generate no noise and only warm slightly within the -40 °C to +90 °C operating range.

What cable sizes and tools must I already have to crimp these 100 pairs properly?

You need 2.5 mm², 4 mm² or 6 mm² (AWG 14/12/10) solar cable and a compatible 4.0 mm crimp tool for the copper silver-plated pins.
