It is a cadmium-plated green accessory that installs into the receptacle housing, occupying a keying position that aligns with a corresponding plug key. This is not a signal-carrying contact — it is a mechanical polarisation feature that forces the correct mating pair before the pins engage. ## Why You Need a Coding Key in a Z-PACK System In a dense backplane with multiple identical-looking connectors, a coding key prevents inserting a daughtercard into the wrong slot. The 5-100526-4 fits the receptacle side of a Z-PACK pair; the matching plug key (typically a different colour or position) completes the polarisation. Without the key, two mechanically identical connectors mate freely — the key forces a unique mating pair, protecting the backplane from a misrouted signal or power rail.","metaTitle":"TE Z-PACK 5-100526-4 Coding Key, Receptacle, Green","metaDescription":"TE Connectivity Z-PACK 5-100526-4 receptacle coding key, cadmium-plated green.
