The Ins and Outs of Connectors in Medical Equipment

Medical equipment manufacturers are placing greater emphasis on higher resolution imaging, viewing, and displays in diagnostic equipment. As a result, EMI and RFI requirements are critical considerations when designing X-ray machines and ultrasound equipment. In addition to resolution requirements, diagnostic equipment is becoming increasingly portable, resulting in demands for smaller, lighter components that are still highly reliable. Because connectors are used extensively in medical diagnostic equipment, there are a number of design considerations manufacturers must implement to conform to these requirements. Materials and filtering of the connector play a key role in shielding to meet EMI/RFI requirements, while pin counts, pin spacing, and contact system design affect the size and life expectancy of the connector.
