Connector, connector system, and use thereof

A connector (10) for sterile connection to a complementary connector (12), wherein the connector (10) comprises

• a connector housing (14) with
• an engagement device (16), which is designed such that
• it can enter into engagement with a complementary engagement device (18) of the complementary connector (12) essentially along an engagement direction (44), and
• that, after the engagement device (16) enters into engagement with the complementary engagement device (18), the connector (10) is displaceable relative to the complementary connector (12) essentially along the engagement direction (44);
• a feed-through opening (24), for feeding a sensor device (34) through;
• a displaceable, sterile covering device (22), which is designed
• to close the feed-through opening (24) in an essentially sterile manner, and
• that, when the connector (10) is displaced relative to the complementary connector (12), the covering device (22) is displaced relative to the connector (10) essentially along the engagement direction (44),
• and with an essentially sterile sensor device (34), wherein
• the sensor device (34) is movable essentially along a sensor displacement direction (52), and wherein
• the engagement direction (44) differs from the sensor displacement direction (52).
