instrumentation to be worn by a patient for remote diagnostics must be small and light. Transportation systems,
systems which must not take up too much cabin space. The performance of defence and aerospace systems, especially drones, is highly-dependent on miniaturisation.

Choosing the connector is rarely (if ever) where a design begins. Yet everything needs to be powered and signals need to be communicated. Connectors often take the brunt of the mechanical and thermal forces endured by a system, so correct specification is vital. Connectors therefore component, must be fit fo
