This document describes the features and characteristics of the 49952A Molded Cable Assemblies - D-Subminiature Assembly. The product is a 37-position shielded D-Sub connector designed for RS-449 applications exposed to high noise environments. It features S-R PVC insulation, foil plus braid shield (super shield), and PVC jacket.
The Belden 49952A molded cable assembly provides a 37‑position shielded D‑Sub connector suitable for RS‑449 applications where high electromagnetic interference is expected. It features 24‑AWG tinned copper conductors, semi‑rigid PVC insulation, a dual‑layer super shield (Beldfoil® tape and copper braid), and a PVC outer jacket.
Key specifications include a 25‑ft assembly length, UL temperature rating of 80 °C, 300 V RMS operating voltage, and compliance with EU RoHS and other regulatory standards. The shield is connected to the connector shell and pin 1 for effective grounding.
