The poles (1 + 2) and (6 + 7) can be used for the electrical connection. For example in SMT versions: TE 1734839-7, Molex 054550-0771, Molex 052745-0797 • Consult Vishay for other screw sizes, lead length, insulation, connector crimping or other features Note • FFC/FPC = Flexible Film Circuit/Flexible Printed Circuit ELECTRICAL DATA AND ORDERING INFORMATION R25 (Ω) R25-TOL.
