Description
Female DB25 Solder-Type D-Sub Connector
Product Overview
The Female DB25 Solder-Type Connector is a commercial-grade, standard-density D-Sub component engineered to deliver stable, high-integrity data and signal transmission. Featuring 25 precision receptacle pins arranged in two parallel rows (13 pins on top, 12 on the bottom), this connector is optimized for permanent wire-to-pin solder termination in custom cable assemblies and panel-mount interfaces.
Each receptacle contact terminates in a rear-facing solder cup that facilitates fast, efficient wire tinning and secure manual soldering. Built with a heavy-duty, tin-plated steel front shell and a high-insulation thermoplastic core, this connector provides robust mechanical strength, reliable grounding, and minimal contact resistance across demanding multi-line circuits.
Key Features
-
Precision Rear Solder Cups: Features hollowed, easy-access solder terminal cups that retain wire strands cleanly during assembly, helping to prevent short-circuits or bridges between adjacent pins.
-
Rugged Steel Front Shell: Encased in a stamped steel outer shell that offers excellent mechanical protection, structural grounding, and shielding against electromagnetic interference (EMI).
-
High-Insulation Thermoplastic Core: Constructed with a glass-filled PBT insulator insert, providing exceptional thermal stability and preventing electrical tracking under high-density wiring conditions.
-
Standard Dual-Mounting Flange: Equipped with side flanged holes to facilitate secure mounting directly to enclosures, control panels, breakout boxes, or standard DB25 plastic/metal hoods.
