Beschreibung
Zusammenfassung:	The invention relates to a wear sensor and a wear element, and to the corresponding assembly and use. The sensor is designed for a wear element on a blade of an earth-moving machine. The sensor comprises an electric sensor circuit and at least one long arm (23) which extends in a detection direction defining a longitudinal axis. The arm (23) has a base (25) and an end. The end wears together with the wear material of the wear element. The arm (23) comprises a plurality of electrical connections (27) that form part of the electrical sensor circuit and extend along the arm (23), at different individual lengths measured in relation to the longitudinal axis. The invention also relates to a wear element of a blade of an earth-moving machine, to an assembly and to the use thereof for determining the wear.
