Omnetics Micro Circular Series (spaced at .050" / 1.27 mm centerline-to-centerline) is ideal for tight spaces and rugged environments. This family of interconnect solutions features a mated length of less than 12.4 mm. Both the male (pins) and female (sockets) are shrouded by the plastic insulator which houses the contacts, ensuring the contacts themselves are protected during mating and de-mating. Outer diameters range from 5.6 mm to 11.3 mm.

Like all of Omnetics core products, the Micro Circulars performance starts up front with Omnetics trusted flex-pin contact system. Gold plating over Beryllium Copper allows users the ability to exceed 2,000 mating cycles. By design, Omnetics flex-pin contact allows for greater flexibility and lower contact resistance than other contact types on the market. Omnetics standard circular insulators sizes come in: 5, 7, 12, 16, 27 and 39 pin layouts, while the connectors themselves are available: soldercup, pre-wired with Teflon® insulated 26 AWG wire, straight thru-hole, and in some cases, right -angle thru-hole. The insulator material is comprised of LCP (Liquid Crystal Polymer). Designers have the ability to add any standard pin counts to a metal shell, ensuring your circular design can be used not only as a rugged I/O solution, but also one that can carry with it EMI friendly characteristics, and much, much more.

Omnetics standard metal shells are machined from a brass alloy, however, other shell materials and plating options are available upon request. Omnetics metal shell circulars come standard in three different orientation types: Threaded, a quarter-turn Twist-lock and a quick-disconnect Breakaway version. Each shell type offers its own benefits for the designer from a ruggedized and usability stand-point.

IP-68 water-tight options as well as panel mount configurations are available within each shell types and corresponding pin count.

Whether you are using these connectors housed inside of a metal shell or stand-alone, these high density circulars have the ability to withstand high shock and vibration while maintaining their electrical integrity. Many standard and custom options are available including custom cable harnesses. Let Omnetics help with your next product design.
