cimco solar connector MC4 for PV cables 2.5–6 mm² model 106028

cimco solar connector MC4 for PV cables 2.5–6 mm² model 106028 is a single-pole photovoltaic connector designed to provide a reliable, weather-resistant electrical connection for solar panels and PV equipment. The connector supports flexible and solid copper conductors with cross-sections from 2.5 to 6 mm² and is intended for use in outdoor PV arrays where secure, low-resistance contact and mechanical stability are required. The design enables straightforward mating with compatible MC4-compatible counterparts to form sealed PV cable joints.

Advantages

The connector offers corrosion-resistant contacts and a tight sealing system to maintain electrical integrity under outdoor conditions. Its ergonomic housing and standard MC4-compatible interface facilitate quick assembly and secure locking without special tools for basic installations. The product's construction ensures low contact resistance and consistent electrical performance over time, suitable for both new installations and replacement of worn connectors in residential or commercial systems.

Suitable for

• Connecting solar panels to string cabling in rooftop PV systems
• Replacement of existing MC4-style connectors during maintenance
• Creating extension runs and branch connections in small to medium PV arrays
• Outdoor installations requiring UV- and weather-resistant cable terminations

Key specifications

• Conductor cross-section compatibility: 2.5–6 mm²
• Connector type: single-pole PV connector with locking mechanism
• Contact material: corrosion-resistant metal (plated copper or similar)
• Insulating housing: UV-stable, weather-resistant polymer
• Rated for outdoor use with sealing to resist moisture and dust
• Suitable for flexible and solid copper conductors within specified range

How to use

Prepare the PV cable by stripping the insulation to the recommended length for the connector. Insert the conductor into the contact pin and crimp or screw according to installer practice and local regulations to ensure a secure electrical and mechanical connection. Assemble the connector housing around the contact, engage the locking mechanism, and mate with the compatible counterpart until the latch clicks to confirm a secure joint. Verify polarity and continuity with appropriate test equipment before deploying the circuit to live operation.

Recommendations

Use connectors within their specified conductor range and environmental limits. Employ recommended crimping tools or approved termination methods to achieve low contact resistance. Inspect seals and locking features after installation and during routine maintenance; replace any connector showing damage, cracking, or degraded sealing. Observe correct polarity and follow applicable electrical safety standards when working on PV systems.
