. 2.1 Number Contacts
The pole number (number contacts) important consideration when
selecting connector for certain application.1.1: Han® 108 Fig.
The manufacturer’s specification relates the current, which all connector
contacts can carry simultaneously.2 Current
The rated current (current-carrying capacity) another selection criterion. the connector has a
protective contact (PE), should counted separately.
DIN 43652 specifies the design and number contacts for only four types
of connectors. Usually, you must take into
account that only useful contacts are counted. Also, certain arrangements have
become common.2: Han® 3A
