770377-1 Description

Short technical summary and product information.

The 770377-1 is a polarizing device (key, plug, post) from TE Connectivity designed for use with the Universal MATE-N-LOK series of rectangular connectors. This accessory ensures proper alignment and polarization during mating, preventing mismating and potential damage.

 

As a keying plug, it fits into the connector housing to create a unique polarization pattern, allowing only the corresponding polarized connector half to mate. This is critical in multi-connector systems to avoid incorrect connections.

 

The part is RoHS3 compliant and REACH unaffected, supporting environmental compliance requirements. It is manufactured by TE Connectivity, a leading supplier of connectivity and sensor solutions.
