Abstract
A low-wear sensor with little structural outlay to detect a combined linear and rotational movement, such as in a print roller (). In one embodiment, a PLCD (Permanent Magnetic Linear contactless Displacement) sensor includes a magnet () which can be rotated about a longitudinally extended coil (). A ring magnet is particularly suitable for this. The linear position of the ring magnet can be determined independently of its rotational movement () by means of the voltage induced in coils (). Detection of the linear position is contactless and thus wear-free.
