Hi-Performance, Small Form Factor, Weight Saving Nano-D Connectors for Medical Electronic Applications

Sunkye International supplies safe, compact, adaptable, and reliable Nano-D connectors and cable assemblies for life-saving medical devices.

Ideal for use within medical electronic equipment, Sunkye’s robust connectors offer an essential technology with more than 70 years of experience. Its products are an ideal solution for medical applications which require extreme miniaturization, space or weight saving, and reliability.

Sunkye’s Nano-D connectors are specified to the MIL-DTL-32139 and use the reliable Twist Pin contact system with 0.635mm contact spacing and 1 AMP current rating. These nano miniature interconnects use twist pin contact technology to provide a reliable connection even in harsh conditions that encounter shock and vibration, all with low separation force and engagement.

Nano-D connector is offered as both rectangular and circular high-performance assemblies. In addition to standard Nano-D rectangular connectors, Sunkye has developed unique Nano-D circular connectors by putting twist pin contacts and nano pitch spacing into a circular shell. Nano-D circular connectors employ the same reliable components and raw materials as Nano-D rectangular products. These very compact connectors also comply with MIL-DTL-32139 performance characteristics. Typical Applications include diagnostic, surgical, and imaging equipment, as well as cardiac-assist devices, disposable equipment, and therapeutic solutions.
