Abstract

An inductive rotational speed sensor, including: a coil body having a coil and connecting lines which at least partially extend axially or radially with respect to the coil windings; a casing formed from a plastics material and at least partially enclosing the coil body; and a fixing device for facilitating a configuration of the casing, the fixing device including: for radially extending connecting lines, a material core clearance in the casing so as to fix the electrical connecting lines at a mutual spacing when configuring the casing; or an anti-twist safeguard to prevent the coil body rotating relative to a tool used for configuring the casing while the latter is being configured, wherein the anti-twist safeguard partially protrudes from the casing, or extends at least up to an external surface of the casing. Also described is a related method.
