The TE Connectivity 5-100526-9 is a coding key receptacle for the Z-PACK backplane connector family. It installs onto the PCB to prevent mismating of connector halves in multi-position backplane systems. The gray color distinguishes this key variant from other coding options in the Z-PACK lineup.
Compatibility and Installation
This coding key is designed for use with Z-PACK series connectors. It is a receptacle-style key that mounts to the PCB, ensuring that only the corresponding plug-side keyed housing can mate in that position. The keying scheme prevents connector damage from forced insertion of an incorrect mating half.
