A transfer assembly for moving work pieces through a press which includes a hollow transfer bar (12) and a motion transmitting mechanism (20) moves the transfer bar (12) inward, outward, and longitudinally for transferring work pieces through the press. A finger (22) is attached to the transfer bar (12) for engaging and transferring work pieces through the press. A proximity sensor (24) is disposed on the finger (22) for sensing the presence of a work piece. In order to establish electrical connection with the sensor (24), an electrical lead is disposed within the hollow transfer bar (12) for connection to the sensor (24). An inline connector (30) electrically interconnects sections (26 and 28) of the electrical lead within the hollow transfer bar (12) to allow the sections (26 and 28) to be removed from the hollow transfer bar (12) and disconnected for movement independently from one another. A junction box (48, 148 or 248) is attached to a support plate (40) and presents an electric al junction (50, 150 or 250) for attachment to an electrical cable (52). A multiple lead conduit (54) electrically interconnects the block (36) and the junction box (48, 148 or 248). In all three embodiments, the multiple lead conduit (54) extends from the block (36) in a direction parallel to the transfer bar (12) and extends through a U-turn (56) inside the support plate (40) to the junction box (48, 148 or 248).
