A wetmate connector for wirelessly communicating data and/or power signals between first and second components, the wetmate connector comprising: a first connector half which is mountable to the first component, the first connector half including a first internal cavity and a first wireless communications device which is positioned in the first internal cavity, the first wireless communications device being operable to transmit and/or receive wireless data and/or power signals, and the first internal cavity being sealed from an external environment at least when the first connector half is mounted to the first component; and a second connector half which is mountable to the second component, the second connector half including a second internal cavity and a second wireless communications device which is positioned in the second internal cavity, the second wireless communications device being operable to transmit and/or receive wireless communications and/or power signals, and the second internal cavity being sealed from the external environment at least when the second connector half is mounted to the second component; wherein the first connector half is movable relative to the second connector half into and out of an engaged position in which the first and second wireless communications devices are in operable proximity; wherein the first connector half comprises a shaft portion which extends axially from the first component and within which the first cavity is located; characterized in that: the second connector half comprises a housing portion which is spaced axially from the second component and within which the second cavity is located; wherein the second cavity comprises an annular configuration and the housing portion comprises an external axial receptacle which is surrounded by the second cavity and is configured to receive the shaft portion of the first connector half; and wherein when the first and second connector halves are in the engaged position, the first wireless communications device is positioned coaxially within the second wireless communications device; whereby the first and second wireless communications devices are operable to communicate wireless data and/or power signals between each other while each is isolated from the external environment in a respective sealed cavity. a first connector half which is mountable to the first component, the first connector half including a first internal cavity and a first wireless communications device which is positioned in the first internal cavity, the first wireless communications device being operable to transmit and/or receive wireless data and/or power signals, and the first internal cavity being sealed from an external environment at least when the first connector half is mounted to the first component;
