ABSTRACT:
An electrical device assembly (120) has a removable signal cable assembly (180). The electrial device assembly (120) includes a circuit substrate (110) which is encapsulated by a device housing (121). The device housing (121) includes two mechanically coupled housing members (130, 140). The housing members (130, 140) are secured together by a retainer (190) mounted to a signal cable (181), that is removably connected to the electrical device assembly (120). Preferably, the housing members (130, 140) have overlapping loop portions (135, 145), and the retainer (190) mounted through the loop portions (135, 145) to secure the housing members (130, 140) together, and to secure the signal cable assembly (180) to the electrical device assembly (120).
