摘要

An inductive presence, proximity or position sensor comprising an inductive coil defining a working or active face of the sensor corresponding to the external face of a covering plate or a substantially plane part of the housing or casing containing said coil, the plate or plane part being made of a metal with high mechanical resistance and being disposed substantially perpendicularly to the coil axis. The plate or plane part ( 4 ) has at least one linear discontinuity ( 6 ), extending at least partly across the plate or plane part ( 4 ).
