Contactless position sensor arrangement, e.g. for locating a linear drive, comprises inductive sensor coils arranged at an angle to the direction of movement of the activation element so that different orientations are possible

摘要

Contactless position sensor arrangement has two sensor coils (50, 52) arranged on a line (48) that encloses an angle of between 0 and 900 relative to the direction of movement of a sensor activating element that comprises a circuit board (20) with conducting surfaces (54, 56), which are separated relative to the direction of movement of the activation element, that interact with the sensor coils. Optimally the enclosed angle of the alignment line of the sensor coils relative to the activation element direction of movement is 45degrees.
