MAXIMUM SOLUTIONS Mill-Max Adds New Omniball Spring-Loaded Contact Options Through-hole and solderThrough-hole and solder-cup s-cup styles notyles now offw offered in spring-loaded pins with rolling ball inered in spring-loaded pins with rolling ball intterferfacacee Mill-Max announces new additions to its Omniball spring-loaded contact product line with solder tail and solder- cup versions, offering options for different termination requirements. The unique Omniball spring-loaded con - tact (patent pending) features a rolling ball interface, enabling mating components to engage in lateral, rotational and angular alignments while providing optimal electrical, mechanical, and structural reliability. Joining the original surface mount style Omniball contacts are through-hole mount and solder-cup termina- tion styles. There are two new through-hole mount contacts featuring different tail lengths, making them suit - able for use on PCBs of various thickness. P/N: 7945-1-15-20-09-14-11-0 has a tail length of .079 (2 mm) while 7945-2-15-20-09-14-11-0 has a .118 (3 mm) long tail. The solder-cup version, P/N: 7949-0-15-20-09-14-11-0, is designed to accept wire sizes up to 20 AWG. It has two press-fit features, a barb, and a knurl, allowing the pin to be pressed in from either direction. The knurl, an anti- rotation press-fit feature, is preferred when maintaining solder-cup alignment is critical. Omniball contacts are spring-loaded pins in which the traditional plunger has been replaced by a gold plated, brass ball. They are designed to simplify and improve the connections made between components which are mat - ed together in a sliding or rotational motion rather than in an axial or vertical orientation. When engaged, the ball compresses and rolls, allowing the mating surfaces to make contact and then easily slide parallel to each other while spring force acts to ensure consistent electrical contact is maintained. This rolling action alleviates the con - cerns of connector damage such as binding, premature wearing and structural failure that may occur when using traditional plunger style spring pins in these types of applications. Features of Omniball contacts include: .030 (.762 mm) maximum stroke gold plating on all components and a .091 diameter ball interface. These spring-loaded pins are durable, they have been tested to 1,000,000 compres- sion cycles and rolled over 67 miles (108 km) at half stroke while still meeting specifications for contact resistance of 20m-ohms max., current rating of 5.5 amps 30C temperature rise and spring force of 55 grams at mid stroke (.015, .381 mm). Omniball contacts are an excellent choice for any application that involves sliding or rotating connections, such as: twist & lock cable connectors smart lens camera connectors rugged and IP rated connectors including quar- ter turn and threaded as well as docking stations, quick connects and blind mating applications.
