wa Pca Load HONDA MR Series connectors has been developed for the data terminal equipment, such as electronic equipment and communications equipment. This series uses the flat terminal system which dives out- standing reliability. With top priority given to economy, the cost has been considerably reduced as compared with the conventional models. MR Series is a group of very small and multi-contact rectangular connectors that can be widely used not High performance Employment of the flat terminal system ensures stable connection. @ Ultra-small size Best suited to applications where space is prime considera- tion because of rigidity, small size and light weight. Versatility Applicable for interconnection of electronic equipment, communications equipment, data terminal equipment, measuring instruments, medical equipment, recreational equipment, and others. High resistance to shock With a dual structure of screws and spring-locks, it can Se ses only for electronic or communications equipment but also for measuring instruments, medical equip- ment, recreational equipment, and others. The numbers of contacts, available with each type, are 8, 16, 20, 25, 34, 50, 60 for soldering, wrapp- ing, dipping, right-angle and crimping types. The types of case is ready for vertical, vertical- horizontal combination, slant, and relay use. endure shacks. @ Dust-proof Because of the dust-proof structure, it is extremely durable even in a hostile environment. @ Easy to connect and release Easily attached with the aid of the mold guide. Spring- locks allow easy connection and release by one touch. @ Complete series available Prepeared 8, 16, 20, 25, 34, 50, 60 contacts for the solder- ing wrapping, dipping right-angle and crimping type (8, 16, 20, 25, 34, 50 contacts), and vertical, vertical-horizontal combination and slant type cases are available. oc Material Material _.
