DIMENSIONS DSX DATA BUS 39 B2TP, H2TP, B4TP & H4TP AIRCRAFT CONNECTOR The aircraft connector comprises two sub assemblies. 1 -- A plug shell fitted with an insert incorporating 2 (B2TP or H2TP) or 4 (B4TP or H4TP) twinax pin contacts. 2 -- one or two connection plugs depending on the number of BUS lines (B2 or B4). If there are two BUS lines (B2TP or H2TP) the two twinax contacts and the connection plug can be installed either in position 1 (B2TP1 or H2TP1) or in position 2 (B2TP2 or H2TP2). The difference between B2TP1 and H2TP1, B2TP2 and H2TP2, B4TP and H4TP depends on the shielded twisted pairs cable that is used. For FILECA F 2709/12 cable the designation used are B2TP1, B2TP2, B4TP. For FILECA F 2709/9 cable the designation used are H2TP1, H2TP2, H4TP. F2709/12 description : Differential impedance = 75 ¦ 5 Ù Shielded twisted pair (each conductor = AWG 20) Outer diameter = .206 (5.35) max. F2709/9 description : Differential impedance = 75 ¦ 5 Ù Shielded twisted pair (each conductor = AWG 22) Outer diameter = .189 (4.80) max. B2TP, H2TP, B4TP & H4TP EQUIPMENT CONNECTOR The equipment connector comprises one receptacle shell fitted with an insert incorporating 2 (B2S) or 4 (B4S) twinax socket contacts.
