Product Listing

UHV 0.61mm DIAMETER COAXIAL CABLE

MDC Europe Limited’s Kapton® insulated in-vacuum wiring is designed for high and ultrahigh vacuum environments up to 260°C. All conductors and braided shields (coaxial cable shields) are silver plated copper wire. Insulation is Kapton® Type-F film that is applied and heat treated to effectively minimise trapped volumes of gas and maintain mechanical strength. Included in this section are MDC Europe exclusive in-vacuum ribbon cables. These ribbon cables are available in either high or ultrahigh vacuum grades. UHV Ribbon cables consist of multiple strands of Kapton® insulated wires that are bundled together with a PEEK® (Polyether-Etherketone) monofilament weaving. MDC Europe ribbon cables are designed to complement its line of Subminiature-C and D feedthroughs. High vacuum PTFE ribbon cable is available as an economical solution for less demanding vacuum applications.

For sensitive UHV instrumentation applications such as AFM (atomic force microscopy) or STM (scanning tunnelling microscopy) requiring minimal loads and maximum flexibility, MDC Europe Limited offers standard and cryogenic fine instrumentation wires. The cryogenic instrumentation wire is suitable for temperatures down to -269°C (4°K-Liquid Helium). Securing and fastening these fine instrumentation wires is made simple with the use of conductive in-vacuum adhesives. Wire strippers and glass-ceramic colour identification beads are some of the accessories offered to facilitate working with MDC Europe extensive selection of in-vacuum wire and cable products.
