1. inductive position sensor, comprise the scale (10) and the vernier (20) that can move relative to one another along measuring route (x), described scale (10) comprises one or several conductors, with the isolated a series of galvanic circles of pitch T, described vernier (20) comprises the inducing conductor (21 to 23 that is connected in electronic measurement circuit along described measuring route in these conductors formation;

  • 42,44) and sensor conductor (31 to 33;

    41,43), and each conductor forms along described measuring route with the isolated a series of staggered hair clip shapes circles of pitch T, it is characterized in that the conductor (21 to 23,31 to 33 of described vernier (20);

    41 to

         44) line up second group that at least one first group and at least one and described first component are opened, each group all has the conductor that interlocks that N the multiple with T/N separates, and described first group by inducing conductor (21 to 23;

    42,44) constitute, described second group by sensor conductor (31 to 33;

    41,43) constitute, the inducing conductor of described first group and second group and the coupling between the sensor conductor take place via the conductor of described scale (10).
