FCT Group – New Metal-Hood FMN4H – Low Profile Version for Limited Installation Heights

As an established manufacturer with extensive experience of connectors, connector-systems, metal and plastic hoods, contacts and cable assemblies, we would like to introduce you to our brand-new, cutting-edge product.

In a joint venture with an internationally operating customer a metal hood was developed, which is particularly suitable for application in mechanical engineering, industrial processing and automation.
Our customer had requested a size 4 hood with the lowest profile possible and a 90 degree cable outlet, in which also a high density connector with 62 wires could be fitted.

During development emphasis was placed not only on fulfilling customer-specific requirements, but also on developing a hood which could be used in multiple applications. As a result the hood was designed with strain reliefs, one for cable diameters up to 13 mm and one for cables with a narrow diameter.

The biggest challenge with this project was the high mating and extraction forces typical for multi-pole connectors and the resulting risk of distortion of the connectors during insertion and withdrawal.
This was solved by adding a fixed knurled-thumb screw with a collar in addition to the conventional positioning of a knurled-thumb screw. The fixed screw assures correct placement of connector and receptacle during mating and extraction.

The hood must be mounted on, or removed from the mating connector with the help of an Allen Key at both ends. Thus it is ensured that the connector is inserted or removed parallel to the mating connector and the contacts on the edge are not unnecessarily subjected to undue pressure.

Our project partner has already filed a patent for this simple yet innovative technical solution.
