MF SERIES | : | CO-AXIAL._ CONNECTORS Overview The MP (Micro Push-on) series is a series of ultra-small-size 7592 coaxial connectors which were developed by mobilizing our company’s outstanding technical abilities to meet the requirements of high-density mounting, smaller size and lighter weight, and adoption of unit structures and improved performance characteristics. These requirements have been demanded in various devices recently. The “‘push-on” system has been adopted in the MP series, and size-wise the connectors in this series have an ultraminiaturized design which is believed to be the ultimate for any 75Q. coaxial connectors. The “one-touch solderless” technique is used in the outer conductors, aiming at attaining epoch-making improvements in the wiring connection, which was the biggest problem in high-frequency connectors in the past. The matching cables are 2.5C-XW (Irrax cables) and 2.5C-2W. They can be used in the frequency bands of 140MHz or lower, which are ordinarily called the intermediate- frequency bands, but they are suitable for various types of microwave communications equipment, various types of radio equipment, satellite communications equipment, measuring instruments, etc. ay -_ a i Y @ oa 3a ® ee . oy LC } a Characteristic Compact in size and lightweight Features They are extremely compact in size and lightweight. The plugs have a maximum outside diameter of 8.7 and an overall length of 16.5mm, and the receptacles have a maximum outside diameter of 10¢ and an overall length of 15.4mm. Thus, they are most suitable for high-density mounting. The receptacles are of the bulkhead type, which can be mounted from either the front or the rear of the panel. Good performance characteristics, high reliability The MP series consists of products that were developed from the beginning on the basis of cost effectiveness with low total cost. This includes good performance character- istics, high reliability and good workability. Their electrical and mechanical perform- ance characteristics and their resistance to vibration have been confirmed, and their excellence is guaranteed. In particular, since their opening parts are covered with outer cylinders, they have a reliability against twisting which is several stages superior to that of the small size coaxial connectors of the past. Superior connection of wiring The one-touch solderless system has been adopted for connecting the wiring. In order to deal with the difficulties of handling (following the miniaturization of the in- dividual parts) the units have been organized in blocks as much as possible, and case of handling has been set as a goal. Thanks to this new system, inconsistencies in the work of connecting the wiring from one operator to another are eliminated, and high reliability is ensured. In addition, thanks to the adoption of this connecting system, the connecting time has been greatly reduced to a fraction of that needed in the connectors of the past. 121
