The Stäubli MC4-Evo Ready Male & Female Connector Pair is the genuine crimp-free, tool-free version of the world's most widely installed solar PV connector system. Instead of a crimping tool, the conductor is gripped by an automatically closing spring clamp using snap-in technology, so a correctly stripped cable end is all that's needed to make a secure, weatherproof connection. Designed for 4mm² and 6mm² single-core photovoltaic cable with an outer diameter of 5.4–7.6mm, this pair is rated 1500V DC and 30A, and is fully mateable with the entire genuine Stäubli MC4 and MC4-Evo product range, as confirmed by TÜV Rheinland interoperability testing at triple test severity.

Important: Cable Compatibility
This connector pair is designed exclusively for 4mm² and 6mm² single-core PV cable with an outer diameter of 5.4mm to 7.6mm. It is not suitable for 10mm² cable. Always confirm cable cross-section and outer diameter before ordering, as fitting an incompatible cable can compromise the spring-clamp connection and the connector's sealing performance.
Important: Installation Requirements
Assembly and commissioning must only be carried out by an electrician or electrically instructed person. Only tinned copper conductors may be used — bare (uncoated), oxidised, or PVC-insulated cables (including type H07RN-F) must never be fitted, as Stäubli prohibits their use for safety reasons. Cable must be class 5 or class 6 flexible conductor per IEC 60228 and comply with IEC 62930.
Please Note: Ordering as a Pair
This listing supplies one male connector (32.0029) and one female connector (32.0030) as a mating pair. Order sufficient sets for the number of in-string or homerun joins required on your installation, and always keep unmated connectors protected with Stäubli sealing caps until final connection.
Good to Know: Tool-Free Assembly
Unlike standard MC4 connectors, the EVO Ready range needs no crimping tool. Once the cable is correctly stripped, the conductor is inserted and the internal spring clamp closes automatically to form the electrical contact — cutting assembly time on site while maintaining Stäubli's full connection reliability.
Crimp-Free Spring Clamp
The automatically closing spring clamp removes the need for a crimping tool entirely, reducing on-site installation time and eliminating a common source of poor crimps in the field.
1500V DC Platform
Rated to the highest voltage tier in the MC4 range, supporting longer PV strings and fewer parallel runs where the array design calls for high-voltage stringing.
Full MC4 Interoperability
TÜV Rheinland interoperability testing at triple test severity confirms this pair mates safely with the full genuine Stäubli MC4 and MC4-Evo 2 portfolio, protecting existing installations during repairs or extensions.
Weatherproof Sealing
Built to the same sealing standard as the wider Stäubli MC4 platform, protecting the connection from moisture ingress and dust across decades of outdoor exposure.
Tinned Copper Contact System
The MULTILAM-style contact system uses tin-plated copper for consistently low contact resistance and long-term corrosion resistance in outdoor PV environments.
Genuine Stäubli Manufacture
Manufactured by Stäubli, the inventor and originator of the MC4 connector standard, so installers get the reference-grade original rather than a compatible third-party copy.

What cable sizes are these connectors designed for?
They are designed specifically for 4mm² and 6mm² single-core PV cable with an outer diameter between 5.4mm and 7.6mm. They are not intended for 10mm² cable.
Do I need a crimping tool to fit these connectors?
No. The EVO Ready range uses a crimp-free, tool-free spring-clamp system — once the cable is stripped to length, the conductor simply inserts and the clamp closes automatically.
What voltage and current are these connectors rated for?
They are rated 1500V DC and 30A, suitable for high-voltage PV string and homerun connections.
Are these compatible with existing MC4 connectors on site?
Yes. TÜV Rheinland interoperability testing at triple test severity confirms these mate safely with the genuine Stäubli MC4 and MC4-Evo 2 product ranges.
What type of conductor should I use with this connector?
Only tinned copper, flexible conductors (class 5 or class 6 per IEC 60228) that comply with IEC 62930. Bare, oxidised, PVC-insulated, or H07RN-F cables must not be used.
Who should install these connectors?
Assembly, installation, and commissioning must only be carried out by an electrician or an electrically instructed person, in line with Stäubli's official assembly instructions.
