Description
DCBST21CFN 21 Position Backshell Connector — BOLTON SKU 59894.
About the DCBST21CFN Backshell
The DCBST21CFN is a Micro-D backshell from the Cinch Connectivity Solutions Dura-Con accessory range, sized for 21-position D-shape connectors. It is a straight-entry design with a crimp ferrule at the cable end so that a cable braid or shield can be terminated to the shell for EMI control. The shell is aluminium alloy with an electroless nickel finish, and the manufacturer lists a backshell length of 0.852 in (21.6 mm) and a wire entry diameter of 0.22 in (5.59 mm). Mounting to the connector is by two 2-56 hex-head jackposts with locking washers. The published operating temperature range is -65 °F to 390 °F. Backshell selection is tied to the mating connector shell size and to the cable outer diameter, so the connector part number and cable build should accompany the enquiry.

Typical applications
Micro-D backshells are used to provide strain relief and shield termination on miniature rectangular connectors in weight- and space-constrained builds — avionics and payload harnessing, UAV/UAS integration, instrumentation looms and test equipment. They are also stocked by MRO and harness repair shops for rebuilding assemblies to the original shielding standard.
