1. An electromagnetic actuator arrangement comprising an electromagnetic actuator device (2), having a housing (4) and at least one armature unit drivable along the or parallel to the axial direction in response to an energization of a stationary, axially oriented coil unit and configured to interact with at least one slide and/or plunger unit (6, 7) extending in the axial direction, and
at least one shift gate (12) which can be disposed on a sliding cam (14) and through which a transverse center plane (56) passes,
wherein
the actuator device (2) comprises a detection device which is designed for the contactless magnetic and/or electrical interaction with the shift gate (12) and which comprises at least one magnetic field and/or electric field detection means which is configured to create and/or detect a detection field acting directly on the shift gate (12), and which comprises a detection field evaluation means (32) which is configured to determine the position of the shift gate (12) by means of the measured detection field,
the magnetic field and/or electric field detection means being at least partially disposed outside the housing (4).
