A sensor for sensing a property of a body, such as vibration or knocking of an internal combustion engine. The sensor includes an outer hollow tubular sensor casing, one end of which is open and the other end of which is closed and is provided on its outside with a protuberance adapted for connection to the body; an end closing member which closes the open end of the tubular sensor casing, and which is fixedly mounted to it; a sensor element for producing an electrical output signal, mounted within the tubular sensor casing; a sensor element side protective member, passing all around the sensor element between it and the inner wall of the tubular sensor casing; a sensor element base end protective member, between the sensor element and the second closed end of the tubular sensor casing; the sensor element side protective member and the sensor element base end protective member being coupled together so as to form an assembly receiving the sensor element in a substantially closed chamber; and an electrically conducting sensor lead structure, connected by one of its ends to the sensor element, for receiving a sensor output electrical signal from it, and passing through an aperture in the end closing member to the outside of the sensor.
