Crimping pliers Knipex PreciForce 97 52 42 — for MC4 EVO2 solar connectors

The Knipex PreciForce 97 52 42 crimping pliers are designed for reliable crimping of MC4 EVO2 solar PV connectors. This professional hand tool from Knipex is intended to produce consistent, low-resistance crimps on photovoltaic cable terminals. Built for use in both field and workshop environments, the tool supports installation quality by delivering repeatable mechanical and electrical connections for solar modules and string assemblies.

Advantages

The tool offers a purpose-built jaw geometry and a ratcheting mechanism that ensure controlled crimp force and uniform terminations without the need for repeated adjustments. Durable materials and precise manufacturing provide long-term dimensional stability and consistent performance under frequent use. Ergonomic handles reduce operator fatigue during extended crimping tasks while providing secure grip for safe operation.

Suitable for

• Crimping MC4 EVO2 solar PV connector terminals on-site and in workshops
• Preparation and assembly of photovoltaic cable connections for residential and commercial arrays
• Maintenance, repairs, and replacement of solar connector terminations

Key specifications

• Compatible connector type: MC4 EVO2 solar PV connectors
• Tool type: handheld ratcheting crimping pliers
• Application: crimping electrical terminals for photovoltaic installations
• Suitable environments: field use and workshop use
• Ergonomic design for reduced operator fatigue

How to use

Place the prepared conductor and crimp sleeve into the appropriate jaw opening of the Knipex PreciForce 97 52 42, ensuring correct alignment with the connector sleeve. Squeeze the handles evenly until the ratchet releases to complete the crimp cycle. After crimping, visually inspect the termination and perform any specified electrical tests to verify low contact resistance and mechanical integrity before final assembly into the PV string.

Recommendations

Use only connectors and sleeves specified for MC4 EVO2 systems and follow the connector manufacturer's torque and assembly guidance. Regularly inspect the pliers for wear or deformation of the crimping jaws and keep the tool clean and dry. Calibrate or check crimp quality periodically according to site quality procedures to maintain consistent electrical performance.
