Abstract: The invention relates to an electromagnetic actuator comprising a wire coil, an armature and a catch, wherein the armature can be moved in an actuation direction, and wherein the catch secures the armature within the electromagnetic actuator. In order to secure an armature of the electromagnetic actuator, extra parts are mounted to the electromagnetic actuator or the armature is attached via a spring. This results in bigger sizes or insufficient stopping characteristics. The present invention overcomes these disadvantages by locating a catch inside the electromagnetic actuator.

Abstract: The present invention relates to a reluctance resolver (100) with an at least partially soft magnetic stator (104) and an at least partially soft magnetic rotor (102) which oppose each other by forming an air gap. The magnetic resistance in the air gap changes periodically on account of a configuration of the rotor that varies over the circumference. The angle sensor has a magnetic flux transmitter which is arranged on the stator and generates a predefined magnetic flux distribution in the air gap via at least one pair of poles. Furthermore, a magnetic flux receiver, which measures the intensity of the magnetic field via at least two pairs of signal poles arranged offset from one another at an angle, is arranged on the stator, wherein an angle value for a position of the rotor in relation to the stator can be derived from the two receiver signals.

Abstract: A pin contact for pressing into electrical engagement with a plated section in a hole in a circuit board. The contact includes a deformable portion for engaging the plated section with a feed-through portion and a terminal portion at opposite ends thereof. An end part of the deformable portion adjacent to the feed-through portion is deformed prior to insertion of the deformable portion into the hole. This substantially eliminates deviation of the feed-through portion from a central longitudinal axis or rotational deviation of the contact caused by pressing of the contact into the hole. A method and apparatus for making the contact are also disclosed.
