Abstract
A displacement sensor module 1 for mounting on a telescopic-type damper 30, a damper/detector assembly including such a displacement sensor module and a telescopic-type damper, and a household appliance including such a damper/detector assembly is provided. The displacement sensor module 1 includes at least one coil element 4, an electronic detection unit 8 connected to the at least one coil element 4 and adapted to detect an impedance change of the at least one coil element, and a coil housing 2 for receiving and additionally or alternatively a coil support 6 for supporting the at least one coil element 4 and for supporting the electronic detection unit 8. The displacement sensor module 1 is adapted to be mounted on a telescopic-type damper 30, wherein in particular the housing 2 or support 6 is adapted to fit over a portion of a pre-assembled damper 30.
