<p>The present invention relates to a signal transfer device which includes at least two signal transfer elements (2, 3). These signal transfer devices (2, 3) are constructed so there is a minimum separation distance between an unprotected input terminal and an unprotected output terminal of the device, where one signal transfer element is configured to generate a magnetic field and a further element is configured to sense the generated magnetic field. The arrangement and configuration of the signal transfer elements (2, 3) is such that the elements provided are located substantially along a common axis with no electrical connection between the elements.</p> |
