 GARNER, N.C., December 01, 2011 - CONEC, a manufacturer of high-quality connectors, has developed and expanded its combination mixed layout D-subminiature connector family by adding high density (size 22) signal contact layouts.

 "The following high density configurations are now available: 19W1, 15W4 and 45W2, in straight solder pin and solder cup versions," said Peter Persico, technical support specialist at CONEC. "These new configurations provide more flexibility for design engineers who need to get more signal contacts in a small space." Persico noted that other styles are available upon request.

 These types of high density connectors save space and are ideal for applications where power, coax and signal contacts are required. Signal contacts can handle up to 3 amps at 60 volts. The power contacts are rated from 10 amps to 40 amps, and coax contacts are available in 50 and 75 Ohm versions. CONEC combination D-subminiature connectors use high reliability gold plated, copper alloy screw machine contacts.  Insulator material is UL 94 V-0 rated paired with tin-plated steel housings. Other housing materials are available, such as copper alloy (for non-magnetic applications) or stainless steel (for harsh environment applications).  The connectors are ideally suited for applications where high reliability, long life and maximum performance are required.

Miniaturization in the smallest place: M8x1 – 8-pos.

Sensor Actor Line Circular Connectors M8x1 – now available with 8 pins!
CONEC has expanded its family of M8x1 circular connectors to provide even more signals in a small space. Overmoulded connectors are now available in an 8-pos axial threaded version with choice of PVC or TPU cable jackets.

The mate to this is an 8-pos female socket with wires, for front mounting to a panel.

All connectors are designed for a temperature range from -25 °C to +80 ° C and meet protection class IP67 in mated condition.

A short history of Ferrites

The history of ferrites (magnetic oxides) began centuries before the birth of Christ with the discovery of stones that would attract iron.  The most plentiful deposits of these stones were found in the district of Magnesia in Asia Minor, hence the mineral's name became magnetite (Fe3O4).

Much later, the first application of magnetite was as 'Lodestones' used by early navigators to locate magnetic North.   In 1600 William Gilbert published De Magnete, the first scientific study of magnetism.   In 1819 Hans Christian Oersted observed that an electric current in a wire affected a magnetic compass needle.   With further contributions by Faraday, Maxwell, Hertz and many others, the new science of electromagnetism developed.

Naturally occurring magnetite is a weak 'hard' ferrite.   'Hard' ferrites possess a magnetism which is essentially permanent.   In time, man-made 'hard' ferrites with superior properties were developed but producing an analogous 'soft' magnetic material in the laboratory proved elusive.

During the 1930's research on 'soft' ferrites continued, primarily in Japan and the Netherlands. However, it was not until 1945 that J. L. Snoek of the Phillips Research Laboratories in the Netherlands succeeded in producing a 'soft' ferrite for commercial applications. Originally manufactured in a few select shapes and sizes, primarily for inductor and antenna applications, 'soft' ferrite has proliferated into countless sizes and shapes for a multitude of uses.   Ferrites are used predominately in three areas of electronics: low level applications, power applications, and Electro-Magnetic Interference (EMI) suppression.

The breadth of application of ferrites in electronic circuitry continues to grow.   The wide range of possible geometries, the continuing improvements in material characteristics and their relative cost-effectiveness make ferrite components the choice for both conventional and innovative applications.
