The TE Connectivity 1744077-1 is a dust cover accessory for the Power Series 50 connector family. It protects the mating face of an unmated connector — whether on a panel-mount receptacle or a free-hanging plug — from debris, shop dust, and incidental contact during assembly, shipping, or equipment downtime. The cover is molded in black plastic and ships in a bag.
Compatibility Check — Which Connector It Fits
This cover is specified for use with Power Series 50 connectors. If you are maintaining or building a Power Series 50 harness and need to cap an unmated end during transit or while the panel is open, this is the matching accessory. It is not a universal cover — confirm your connector is from the Power Series 50 family before ordering.
