Low Profile D-Sub Filtered Connectors

D-Sub Filtered Connectors

The low profile d-sub Series 500  EMI filtered connectors are cost effective, highly reliable and feature a .318" footprint for 90 degree PCB connectors and a low profile housing on straight PCB connectors. These low profile connectors are "drop-in" replacements for standard unfiltered d-sub connectors.

Low profile d-sub 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.
