An inductive sensor device for detecting a magnetic field change caused by an object approaching in the region of an influencing side of the inductive sensor device includes at least one coil system having a transmitting coil fed with alternating current and first and second receiving coils. The two receiving coils are connected in series in opposite senses, the first receiving coil is disposed in front of the transmitting coil and the second receiving coil is disposed behind the transmitting coil, relative to the influencing side. A screen is provided behind the second receiving coil relative to the influencing side. An inductive proximity sensor with an inductive sensor device is also provided. |
