Low Profile D-Sub Filtered Connectors


Low Profile EMI Filtered D-Subminiature Connectors

Series 500 Low Profile D-Sub Filtered Connectors

The Series 500 Low Profile D-Subminiature Connectors are cost effective, highly reliable EMI filtered D-Sub connectors that feature a .318" footprint for 90 degree PCB connectors and a low profile housing on straight PCB connectors. Our Low Profile Filtered D-Subs are "drop-in" replacements for standard unfiltered D-Sub connectors.

D-Sub connectors use tubular capacitors for high performance EMI filtering. Quality features for these connectors include board lock mounting, metal front shells and gold plated contacts.

Low Profile Subminiature D Connectors are an ideal solution to FCC/EC/VCCI emissions problems. These connectors are designed to protect equipment from external EMI noise and eliminate system glitches.
