Rely-On Connectors

Molex Rely-On Connectors are compact 1mm-pitch wire-to-board connector solutions for design engineers who demand high performance and durability in harsh conditions. These connectors ensure robust PCB retention and reliable signal integrity, helping customers reduce assembly issues and improve product dependability. The Rely-On connectors feature a dual-split nail design and an increased solder contact area with a locking system, which helps prevent accidental connector disengagement. These connectors comply with USCAR2 Class V1 and LV214 Class S1 for vibration and mechanical shock. The Rely-On connectors feature in gold-plated copper alloy contacts. Typical applications include automotive, compact portable appliances, smart speakers, tablet PCs, wearable devices, medical wearables, VR/AR headsets, home appliances, HVAC, and industrial automation.
