Mating of the post and receptacle contacts of this system is very tolerant. This is made possible by a post with a burr-free lead-in and a receptacle contact featuring double cantilever beams and anti- overstress stops. AMPMODU receptacle contacts and posts categori- cally fall into three general classifications of products, which include: board mounted posts and recepta- cle assemblies, post headers and wire-applied contact housings for crimp snap-in pin and receptacle contacts. Board mounted receptacle assemblies are available in various geometries, offering packaging interconnections that include perpendicular, parallel and stacking capabilities. Crimp snap-in pins for 26-22 AWG [0.12-0.4 mm2] wire and crimp snap-in receptacles for 32-20 AWG [0.03-0.6 mm2] wire provide excellent discrete wire terminations. Housings for these contacts provide ease of handling terminations in high density applications. Machine applied termina- tions, through matched application equipment, are geared for virtually any pro- duction volume requirement, for the lowest possible applied cost. AMPMODU mating posts are supplied typically as headers. They are available in various populations to meet the interconnection and packaging require- ments of most systems. However, in instances where packaging configurations do not lend themselves to the economies of headers, Tyco Electronics can pro- vide application equipment for the discrete location of individual posts. Looking at the electronic industry's standard “levels of packaging,” the AMPMODU .025 [0.64] square intercon- nection system is primarily used in levels three and four. In level three it is used as a connection between two or more printed circuits. A mother/daughter board connection is typical. In level four it is used as a connection between two subassemblies, such as a power supply and an asso- ciated subassembly. It is also important to note this product can serve as an interconnection in more than one level, depending on the application. The .025 [0.64] square interconnection system offers the most complete line of post/receptacle pack- aging products available today. This system, rated at 3 amperes per contact, has been used by almost every industry and marketplace over the last decade and is one of the oldest, most ver- satile and reliable intercon- nection systems employing .025 [0.64] square packag- ing technology. Offers standard, intermediate and high pressure contact forces Insulation Support Barrel Wire Crimp Barrel Rugged—self- supporting one-piece contact body Wire entry for post to receptacle misalignment Reliability—dual cantilever spring contact design and built-in anti-overstress Cantilever Beams Wide Misalignment Tolerance Anti-overstress The AMPMODU receptacle cross-section is primarily rectangular, with rounded corners. Two integral canti- lever beams contact the mating square or round male posts. Deflection of these spring members is limited by anti-overstress stops, and excessive per- manent deformation is pre- vented. This feature allows a wide range for tolerance of misalignment of mating contacts. The configuration of the receptacle completely encloses the spring members preventing damage during handling and assembly and makes the system compati- ble with automatic applica- tion techniques. Note: Application of a contact lubricant is part of the manufacturing process of all AMPMODU tin-plated crimp products. However, it is not part of the manufacturing process of products that customers will solder, then clean. For these products, Tyco Electronics recommends that customers use contact lubricant. See the Tyco Electronics web page for further information. Receptacle Contacts Receptacle-Closed Entry Housing Design The closed entry housing style better eliminates the chance of a mating post stubbing on the edges of the receptacle contact.
