Custom Power Supply Cables for Medical Devices

Custom Power Supply Cables for Medical Devices

When you’re working on your medical device, you don’t want to be slowed down by your power supply cable requirements. If you’re wondering whether your needs are standard, or you need to request a custom option, we’ve got your bases covered. We’ll review the standard and customized options you may need for your medical device power supply unit. 

Standard Cable Assemblies

Most medical device manufacturers will get by with a standard cable assembly. Everyone we work with gets Main Power and PCle cables. About half get the 4-pin ATX and 8-pin EPS12V cables. Not many get the dual 4-pin cables, as they are being phased out. Approximately 90% of customers get the SATA cables. Our newest cable is the 12VHPWR

Below are the standard cable assemblies we offer, with photos. The lengths available are measured by starting at the exit point of the power supply and going to the base of the connector housing, with length tolerance being +/- one inch.
