Abstract
A proximity detector has a casing containing a probe (4) and a printed circuit (3), the upper end of the casing being closed by a plug (35) provided with a filling orifice (14) and with connecting-pins (36). The nozzle of a plastic injector (13) is fitted in position within the filling orifice, said nozzle being provided with two adjacent ducts. A hardenable resin is caused by centrifugation to flow into the casing via a first duct while simultaneously driving-out the air which is present within the casing via the second duct, thus ensuring rapid and efficient filling. When the casing has been filled and the resin has hardened, the injector (13) is cut-off in close proximity to the plug (35). Complete filling can be checked by inspecting the surface appearance of the two leading portions of solidified resin flux which are thus visible at the level of the orifice (14).
