Positronic XC/XCL Precision One-Piece Closed Backshells

Positronic XC/XCL Precision One-Piece Closed Backshells are designed for use with D-sub connectors utilized for switching or shorting. These backshells are available in sizes 1 through 6, standard (XC) and low-profile (XCL) styles, and with rotating or fixed jackscrews. While both the XC and XCL series are suitable for standard and high-density D-sub connectors with stamped shells, XC backshells are also built for mixed-density D-sub connectors. Positronic XC/XCL Precision One-Piece Closed Backshells feature one-piece construction, low outgassing, and EMI protection due to the metal design. Ideal applications include military, aerospace, spaceflight, and industrial.
