Winchester Electronics has a new family of Non-Magnetic Combination
D-Subminiature connectors designed for medical systems, such as MRI
machines, that require non-magnetic coils.
The D-Sub connectors are also well-suited for use in any medical,
communication, computer, and test and measurement applications where
non-magnetic components are advisable.
The connectors are fabricated using non-magnetic material, resulting in
residual magnetism rated at less than 30 gamma (nT). This allows
placement in or near the imaging area in advanced medical imaging
equipment.
The non-magnetic connectors combine signal, power, and RF coaxial
contacts within a variety of industry standard shell sizes and connector
insert configurations. They can be mixed and matched with standard
component parts.
Power contacts are available in 10, 20 and 40 ampere versions. RF
coaxial contacts are available in 50 and 70 ohms with a frequency rating
up to 900 MHz.
Insulator and signal contact specifications are similar to those for
standard components. Insulator resistance per mated contact is 5,000
M-ohms and dielectric strength is 50 kV/mm. Signal contact maximum
current rating is 5 amperes and operating voltage is 250 volts.
Resistance per mated contact pair is less than or equal to 2.7
milli-ohms/ampere.
As with all combination D-subminiature connectors, the non-magnetic
versions are supplied with solder signal contacts pre-seated into the
connector insert and are capable of operating up to 5 GHz. Extremely
durable, the non-magnetic connectors are rated for 500 matings minimum.
