It is a polarization accessory that fits into the Z-PACK connector housing to prevent mismating of identical-looking connectors in a backplane system. By inserting these keys into specific cavities on the male or female connector, you define a unique mating pattern — only a receptacle with the complementary key arrangement will engage. This is common practice in high-density backplane designs where multiple connectors of the same size sit side by side and a mis-mate could short power rails or route signals to the wrong card. ## Compatibility and Placement The 3-100525-2 is designed for use with Z-Pack series connectors. It snaps into the designated keying slots on the connector housing — the blue colour distinguishes it from other key positions in the same system. The coding key does not carry current; its only job is mechanical polarisation. When you order a Z-Pack connector, the housing comes with empty keying slots; you populate them with the plug keys (like this one) or receptacle keys as your system's mating scheme requires.","metaTitle":"TE Connectivity 3-100525-2 Z-PACK Coding Key, Brilliant Blue","metaDescription":"TE Connectivity 3-100525-2 Z-PACK coding key plug, brilliant blue.

It provides mechanical polarisation so that only a mating connector with the complementary key arrangement can be mated, preventing mis-mating in multi-connector backplane designs."},{"question":"Is 3-100525-2 compatible with all Z-Pack connectors?","answer":"The 3-100525-2 is designed for use with Z-Pack series connectors. It fits into the keying slots on the connector housing to set the polarisation scheme. Compatibility should be verified against the specific Z-Pack connector part number, but the key is a standard accessory for the series."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icsourcedirect.com/te-connectivity-amp-connectors/3-100525-2","citationPolicyUrl":"https://icsourcedirect.com/llms.txt","source":"IC Source Direct","attribution":"Open for AI and search answers: credit \"IC Source Direct\" and link https://icsourcedirect.com/te-connectivity-amp-connectors/3-100525-2 when reusing this data.
