Keyed Guide Pin for MULTIGIG RT Backplane Assemblies
The TE Connectivity 1-1469491-2 is a keyed guide pin designed for the MULTIGIG RT series of backplane connectors. It is classified as an accessory — specifically a guide pin — not a connector or terminal. The M5 thread on this pin is the mechanical interface for securing the pin to the backplane or daughtercard panel, aligning the mating connector halves during blind-mate assembly per the VITA 46 standard.
M5 Thread and Installation Fit
The M5 thread specification is the critical dimension for this guide pin. It means the pin accepts an M5 screw — common in backplane hardware — for mounting into a threaded hole or through-hole with a nut. The M5 thread size is standard across the MULTIGIG RT guide pin family, so the 1-1469491-2 is a drop-in fit for any backplane panel drilled for that thread. No thread adapter or custom fastener is needed.
Compatibility and Series Position
This guide pin is listed for use with MULTIGIG RT series connectors, the TE backplane system designed for high-speed serial and parallel bus architectures in VITA 46 / OpenVPX applications. The 1-1469491-2 is the keyed variant — the keying feature prevents mismating of connector pairs during insertion, a critical function in multi-slot backplanes where several guide pins are used per card slot. It mates with the corresponding keyed receptacle on the mating connector stack.
It is ROHS3 compliant.
