Broad lineup of contact layouts In addition to standard solder type con- tacts (size No. 20, rated current 5 A), special contacts such as coaxial, high- voltage, and high-current types are available. Special mixed-content layouts combining these contacts are also available, in addition to the basic layouts for 9 to 50 conductors. The special con- tacts are ordered separately (shown on pages 27 and 28). e As specified by RS-232 and JIS C-6361, the interface between Data Cir- cuit Terminating Equipment (DCE) and Data Terminal Equipment (DTE) is a 25- position D Subminiature connector, as used in data communication and other equipment. @ Wire connection by soldering Use standard wire under 20 AWG. The capacity of the soldering iron must be be- tween 40 and 60 W. Install special con- tacts In the insulator after being terminat- ed. e Connector mating combinations Mate connectors that have the same shell sizes and contact layouts but dif- ferent contact sex. Example: (a) DAM-15P (15 conduc- tors, male pin side) com- bined with DAM-15S (15 conductors, female sock- et side) (b) DBM-17W2P (17 conduc- tors, pin side, with two special! contact cavi- ties) combined with DBM-17W2S (17 con- ductors, socket side, with two special contact cavi- ties) 260 Sys 2376 B-05 DBM -25 P DBMF-13W3S DBM -25 S-0001 Modification codes (see Note 2) | Contact type: P...Pin,S...Socket 9, 15, 25,37, 50 and special e Contact arrangements: arrangements (see Note 1) No designator...

For example, 13W3 means that of the 13 contacts, three are special and the remaing ten are standard. b) Connectors come without special contacts. Refer to page 27 and 28, and order separately. (2) Modification code 0001 a) Means two pieces of jack screws (P/N D20418-J2) are mounted. Ap- plies to DBM-25S only. b) DBM-25S8-0001 is a receptacle meeting the requirements of JIS-C-6361.
