The IEC 60601-1 states maximum requirements concerning the protection from electric shock for medical applications in which patients and operators can get into direct contact with electrical equipment and systems. In order to reduce risks to a minimum, manufacturers must integrate two means of protection in their products. This white paper shows – based on the example of the ODU plastic circular connector series ODU MEDI-SNAP® – how supplier knowledge can contribute towards the development of IEC 60601-1-compliant electrical equipment and systems.
