The KNIPEX PreciForce 97 52 42 6 is a specialised crimping tool, developed exclusively for MC4®/MC4® Evo 2 (Multi-Contact) solar connectors, widely used to connect photovoltaic panels and renewable energy installations.
Unlike a universal crimping plier, this model is factory-calibrated for a single application, which it performs flawlessly: safe, repeatable crimping of MC4 connectors, without requiring any additional adjustment from the user.
The integral lock holds the crimping jaws closed until the factory-set optimal pressure is reached, at which point the pliers open automatically. This lets the user focus entirely on positioning the connector, without the risk of an incomplete or excessive crimp. The lock can be released manually, and the crimping pressure can be readjusted if needed.
The improved crimp geometry ensures very good electrical conductivity of the finished connection, essential for the long-term safety and efficiency of photovoltaic installations. Force is transmitted via a toggle lever system, which reduces hand effort and fatigue during repeated use, typical of large-scale solar installation work.
The tool body is forged from high-grade chrome vanadium steel, oil-hardened, with a burnished finish, while the multi-component handles provide a secure, comfortable grip even during extended use on site. Made entirely in Germany, the KNIPEX 97 52 42 6 is part of the PreciForce family, where every crimping application has its own dedicated version with a specially machined crimp profile.
Important note: this tool is calibrated exclusively for MC4®/MC4® Evo 2 solar connectors; it is not intended for other connector or terminal types.
Sometimes we're really tough on our pliers. We try to break them, just to find out what makes them good and long-lasting. Because we don't want to leave anything to chance, we take a long, close look at every detail.
The steel used by KNIPEX is precision-hardened, with defined chrome and vanadium content, guaranteeing top performance and a long service life — even though this requires special production and costs a little more. But our high product standards demand it.
Every angle, every edge radius, the hardness and sharpness of the cutting edges, the precision and smoothness of the joint, the handle shape and the finish are constantly reviewed, tested and improved — so the tool you hold today still performs the same way after a decade of intensive use.
This special tool is built for one job, and it does it perfectly: safe, repeatable crimping of MC4 solar connectors, with consistent pressure and no compromise on the quality of the electrical connection.
What is the KNIPEX 97 52 42 6 used for?
