Memory Cards

A broad range of memory products for embedding into systems.

From removable memory through to secure memory ICs, Solid State Drives (SSDs) and modules.

Working closely with our suppliers, the manufacturers of the products, we have ensured these products can meet the demanding requirements of industrial applications: all those situations where commercial is not secure enough, not rugged enough and/or has no guaranteed long-term availability.

Peace of Mind

For decades, organisations across Europe have been using – and continue to use – products recommended and supported by Nexus, and our customers have the peace of mind knowing that their memory solutions will stand up to the most extreme situations and remain secure.

Applications engineers at heart

Moreover, we are far more than distributors or resellers of memory products. We are applications engineers at heart. We have sound advice to offer and can work under terms of strict confidentiality. Also, such is the close relationship we enjoy with our suppliers, we can work with them to develop new solutions – see ‘Custom Products’ below.
