RF Immune TA4F Connectors – MX202, MX391

FAQ #3287 Updated February 21, 2018

Question:

The new “RF Immune” TA4F Connector cover has what appears to be a pin or tiny screw on it. What is it, what is its purpose and what tool is needed to remove it?

Answer:

The new “RF Immune” TA4F connector features a metallic cover, which compares to the standard TA4F plastic cover. The metal cover provides additional RF shielding. The small pin or screw on the metal cover is a hex setscrew and provides positive electrical contact between the cover and the connector body. To remove the setscrew, use a 0.9-mm or 0.035-inch hex socket screwdriver. This will allow the connector’s metal cover to be unscrewed for internal inspection.
