What This Guide Module Does
The TE Connectivity 5223979-2 is a guide module accessory in the UPM series. It aligns and protects the connector halves during blind-mate engagement in a backplane or panel-mount setup — without it, the signal pins risk stubbing or bending before the contact surfaces meet. Designed for use with UPM-series connectors, this module keeps the mating sequence straight and reduces insertion force damage on the first mate.
