A connector (10) is provided for sterile connection to a complementary connector (12). The connector (10) has a housing (14) with an engagement device (16) to engage a complementary engagement device (18) of the complementary connector (12) along an engagement direction (44). The connector (10) is displaceable relative to the complementary connector (12) along the engagement direction (44) after the engagement device (16) engages the complementary engagement device (18). The housing (14) has a feed-through opening (24) for receiving a sensor (34) and a cover (22). The cover (22) is displaced relative to the connector (10) along the engagement direction (44) to close the feed-through opening (24) in a sterile manner. The connector (10) also has a sterile sensor (34) that is movable along a sensor displacement direction (52) that differs from the engagement direction (44).
