The present invention relates to a magnetic proximity sensor for checking the operation of railway vehicle doors, which comprises: a power conversion unit which converts input power supplied from a power input unit into driving power; a magnetic sensor which receives the driving power from the power conversion unit and operates to output a magnet detection signal when it detects a magnet; and a comparison unit which compares the magnet detection signal output from the magnetic sensor with the input power supplied from the power input unit and outputs a motion detection signal of a set size according to the magnet detection. According to the present invention, when applied to electric doors installed in railway vehicles for passenger transportation such as trains, it is possible to detect the operation of the door, such as opening and locking, in a non-contact manner. Therefore, stable monitoring and operation of the door are possible even if the operation of passenger transportation vehicles occurs for a long time, thereby having an effect of replacing a contact type switch that is currently used.

    본 발명은 철도차량 출입문 동작 확인용 자기근접센서에 관한 것으로, 전원입력부에서 공급되는 입력전원을 구동전원으로 변환하는 전원변환부와, 상기 전원변환부의 구동전원을 공급받아 작동되어 자석을 감지하면 자석감지신호를 출력하는 자기센서와, 상기 자기센서에서 출력되는 자석감지신호를 상기 전원입력부에서 공급되는 입력전원과 비교하여 자석 감지에 따른 설정된 크기의 동작감지신호를 출력하는 비교부를 포함하는 것을 특징으로 한다. 본 발명에 따르면, 열차 등의 승객 운송용 철도차량에 설치되는 전기식 출입문에 적용시 출입문의 열림 및 잠김 등의 동작을 비접점 방식으로 감지할 수 있어 장시간 승객 운송용 차량의 운행이 발생하더라도 안정적인 출입문의 동작 감시 및 구동이 가능해 기존에 사용중인 접점방식의 스위치를 대체할 수 있는 효과가 있다.
