A sensing assembly comprising: a housing portion including a primary mating face; a base portion including a secondary mating face; at least one first retaining structure provided in relation to a first of the primary and secondary mating faces (128, 130); at least one second retaining structure provided in relation to a second of the primary and secondary mating faces (128, 130); and a mounting portion; wherein the at least one first retaining structure and at least one second retaining structure are configured to engage one another so as to at least partly retain the housing and base portions together, upon the primary and secondary mating faces being positioned adjacent to one another along a junction and shifted relative to one another along the junction, wherein the base portion when assembled in relation to the housing portion can have two possible orientations, either of a first orientation or a second orientation that is rotated 180 degrees relative to the first orientation about an axis extending perpendicular to the junction, wherein the mounting portion is configured to jut out from the sensing assembly in a manner diametrically opposed to the directional orientation of a sensing face of the sensing assembly when the base portion takes on the first orientation, and configured to jut out from the sensing assembly in a direction at a right angle relative to the directional orientation of the sensing face when the base portion takes on the second orientation, and wherein at least one protrusion is formed on one of the mating faces and at least one complementary recess is formed on the other of the mating faces, and wherein upon the primary and secondary mating faces being shifted relative to one another along the junction so as to align the base and housing portions, each of the at least one protrusion fits into or otherwise engages a respective one of the at least one complementary recess so as to restrict the base and housing portions from experiencing further shifting. a housing portion including a primary mating face; a base portion including a secondary mating face; at least one first retaining structure provided in relation to a first of the primary and secondary mating faces (128, 130); at least one second retaining structure provided in relation to a second of the primary and secondary mating faces (128, 130); and a mounting portion; wherein the at least one first retaining structure and at least one second retaining structure are configured to engage one another so as to at least partly retain the housing and base portions together, upon the primary and secondary mating faces being positioned adjacent to one another along a junction and shifted relative to one another along the junction, wherein the base portion when assembled in relation to the housing portion can have two possible orientations, either of a first orientation or a second orientation that is rotated 180 degrees relative to the first orientation about an axis extending perpendicular to the junction, wherein the mounting portion is configured to jut out from the sensing assembly in a manner diametrically opposed to the directional orientation of a sensing face of the sensing assembly when the base portion takes on the first orientation, and configured to jut out from the sensing assembly in a direction at a right angle relative to the directional orientation of the sensing face when the base portion takes on the second orientation, and wherein at least one protrusion is formed on one of the mating faces and at least one complementary recess is formed on the other of the mating faces, and wherein upon the primary and secondary mating faces being shifted relative to one another along the junction so as to align the base and housing portions, each of the at least one protrusion fits into or otherwise engages a respective one of the at least one complementary recess so as to restrict the base and housing portions from experiencing further shifting.
