Abstract	This paper describes a novel non-contact signal transfer mechanism for transferring multiple signals over the rotating interface through electromagnetic means. This signal transfer mechanism is configured for the transfer of temperature signals of a Spacecraft Mechanism. FE Analysis of rotary transformer was carried out for optimization of size and operating parameters. In the Signal Electronics portion, operating range of JFET is optimized to achieve uniform gain during amplitude modulation. The system was realized and linearity of 2 % and resolution of 1% of Full Scale Division (FSD) was achieved.
