DCMY21WA4S Description

Short technical summary and product information.

The ITT Cannon DCMY21WA4S is a D-Subminiature combo receptacle from the COMBO D series. It has a 21WA4 contact arrangement with 17 size 20 signal contacts and 4 empty size 8 cavities for coax or power contacts. The connector is a receptacle with female sockets.

 

Electrically, the signal contacts are rated for a maximum current of 7.5A, with a maximum contact resistance of 10mΩ. The dielectric withstanding voltage is 500VAC at sea level. The operating temperature range is -55°C to +125°C, and the connector is rated for 50 mating cycles.

 

Mechanically, the shell is steel with a yellow chromate over zinc finish. The insulator is black thermoplastic, type PCT, UL 94V-0 rated. Contacts are copper alloy with a gold flash finish (Performance Class 3). The connector is shielded and features a panel mount with a dual float mount method, using solder cup termination.

 

This connector is suitable for applications requiring a mixed contact layout, such as industrial control systems, data communication equipment, and instrumentation where signal and coax/power connections are needed in a single D-Sub footprint.
