Only Connect: Molex introduces D-Sub earthing connector

Welcome to another post in the series by Nick Locke, of Nicab Ltd, who has more than 15 years experience in the electronics manufacturing industry specialising in interconnection cable assembly. This post is about a D-Sub earthing connector.

This week I bring you a quirky new product from Molex, the D-Sub Earthing Connector.

Yes, that’s right an earthing point specifically designed around the traditional D-Type connector. What’s more it’s waterproof!

According to Molex, the Earthing Connector protects equipment from stray voltages through a secure and low-impedance connection to earth. The IP66 and IP67 NEMA-rated Earthing Connector protects sensitive equipment such as telecommunications base stations against water ingress in the field in mated condition.

A cap attached to the connector allows the unmated connector to be IP protected as well.

I have to say this product is a little unconventional, but I can see the attraction especially with the waterproof element. If you already make products that have a D-Sub cut out in the metal work then it reduces the tooling costs.

Molex also says:

“Mobile equipment such as base stations often operate in harsh environments and need flexible and fast installation and servicing. This means that the connections are exposed to the elements. The D-Sub Earthing Connector addresses the needs of fast installation and combines this with an industry known and robust form factor.”

The D-Sub Earthing Connector features a 40.0A contact to an Earth cable (8 AWG) with straight termination and a metal sealing frame for rear installation. Two hexagonal bolts enable the connector to be mounted on the housing.

If you consider how many industrial devices require extra-large earthing points then I guess this product does make a lot of since. It will be interesting to see how many people decide to design this into their products. Only time will tell.
