Omnetics' Waterproof Micro-Circular Connectors Lead New Generation of Electronic Miniaturization

MINNEAPOLIS, MN -- Micro-sized (.050 inch pitch) connectors in compact metal or over-molded polymer shells offer dramatic size and weight reductions for circuits requiring multiple pin interconnection systems. Near the smallest in the industry, they are less than one-half inch diameter for 28 positions.

Omnetics delivers an extensive array of micro-circular connector styles and formats, including a line of IP67 waterproof connectors and cables. Configurations available include solder cup, thru-hole and pre-wired systems. Multiple metal shell options provide the designer a variety of locking systems and can also be used to connect cable shielding to panel mounted connectors on the instrument chassis. Over-molded polymer shells are also available and can be used to reduce overall diameter and weight. A number of mating systems from cable to cable and cable to panel mounts are exhibited in Omnetics' Micro 360 Catalogs and can be seen at:

Omnetics' connectors employ nickel and gold plated Beryllium plated Flex-pins® and are available as standard products ranging from 5 to 39 positions per shell. Current rating is set for up to 3 amperes with a dielectric withstand voltage of 660 volts and insulation resistance of 5000 Meg-ohms at 500 volts dc. The Micro-miniature connectors are designed to perform consistently up thru 20 g level of vibration with no discontinuities greater than 1 microsecond and pass 50 g level of shock. Metal shells and plating options include nickel, brass, stainless steel and black oxide finishes. Shielded cabling is banded to the metal shells giving excellent EMI protection. Standard and custom back-shells are available, as well as pre-molded strain-reliefs to help users fit the size and shape of the cable attached. The designer can specify mixed signal formats to reduce even further size, shape and weight of the interconnection systems as a whole. When combining two connectors into one using two different pin types or pin sizes, inside one insulator/shell, the designer has reduced the number of outer shells and concentrated the signal and power entry area into the instrument. This significantly improves the miniaturization of the equipment involved.

Circular connectors are a natural shape for handling round cabling from high-speed digital, analog and power systems. Designers are now being pushed to reduce both size and weight within their existing electronics to allow for rugged portability within the field. Immersion sealed connectors and cable systems are needed in many applications. Mobile robotic equipment, hand-held electronics, Future Soldier systems among others, now require multiple circular connectors to route command signals and functions to different extremities within their instrumentation. Evolving unmanned aircraft design is demanding interconnect miniaturization, as many new UAV's are reducing size and weight in an effort to enable the units themselves to be launched by hand. To do so, the units must remain small and light enough for the launch itself to be conducted by a single person. Omnetics micro-miniature circular connectors also offer high speed digital surveillance equipment the circuit speed and performance they need in order to ensure the highest signal integrity.
