Latest Yamaichi Y-Sol4 series field-assembly connectors, for 4 to 6mm2 cross section cables, now in stock at Cyntech Components

Cyntech Components, a specialist supplier of electro-mechanical components and power supplies, introduces additional connector sizes in the Yamaichi Y-Sol4 series. This range of MC-4 compatible, connectors is designed for field assembly, without the need for a crimping tool, simply by screwing the two parts of the connector together. These new connectors extend the existing range by providing for cables with cross-sectional area from 4 to 6mm2.

The MC-4 type of connector is a single-contact, in-line format male/female connector defined by its 4mm diameter contact pin and receptacle. Commonly used to connect photovoltaic panels, these connectors feature a high current, high voltage specification combined with a sealed design. Cost pressure in the photovoltaic industry has resulted in a move to cables with thinner outer diameters with lower material costs and Yamaichi has responded to this trend by developing new connectors in its Y-Sol4 range to support cables with cross sections of 4 to 6mm² and outer diameters of 4.5 to 6.1mm.

Commenting on the advantages of the Yamaichi S-Sol4 design, Dave Mellor, managing director of Cyntech Components, said, “These connectors are designed for quick, reliable and effective field assembly without the need for soldering or crimping. It is simply a matter of inserting the stripped cable into the connector body, securing it with the spring clamp and then aligning the two halves of each connector before screwing them together. The video on our website shows just how easy this is and also how the connectors mate together with a push-fit, snap-lock action.”

As well as the new connectors for thinner cables, Cyntech can supply the existing Yamaichi Y-Sol4 connectors for outer cable diameters from 6.1 to 7.6mm. There are also versions to suit cables with smaller cross sections, from 1.5 to 3.5mm2. All the Y-Sol4 connectors are sealed designs with ingress protection to IP68 level, a TÜV rating of 1000V and a current rating up to 47A, subject only to the cable’s current handling capacity.
