A male and female connectors and a method for providing electrical connection between a patient interface module (PIM) and an intravascular sensing device carrying more than two signal leads. A four-electrical-contacts male connector includes three elongated hollow tubular male bodies concentrically disposed around one another in an expanded telescopic fashion to define three stepped banded outer surfaces, where one electrical contact is formed on an inner surface of the innermost male body, and the rest on the stepped bands. The female connector includes three spaced-apart hollow tubular female bodies concentrically disposed around one another and a shaft disposed within the innermost female body, being sized and configured, respectively, to mate with the three stepped bands and a central cavity defined by the innermost male body of the male connector.
