Two-Piece Shielded Backshell for Standard DB25 and HD44 D-Subs
The Amphenol 8655AZBT1A11KLF is a two-piece backshell designed for D-subminiature connectors, specifically sized for standard 25-position and high-density 44-position D-subs with a Shell Size B. It provides a shielded enclosure for the cable termination area, using a plastic body with a metallized coating and a nickel-plated finish to control EMI emissions and protect signal integrity. The backshell includes 4-40 mating screws, the standard thread for securing D-sub backshells to the connector, and assembly hardware with grommets for strain relief.
Shielding and Cable Exit for Signal Integrity
The metallized plastic construction provides a shielded path from the cable braid to the D-sub shell, critical for maintaining signal integrity in noisy industrial or data-communication environments. The included grommets grip the round cable jacket, providing strain relief that keeps the termination from pulling loose under tension.
