Series Code |
Model 2KN - Plain spring terminal plug |
Pitch 5.08 - 5.08mm |
Poles 02–24 - Two-digit count from 2 to 24 poles |

The 2KN family uses straight-through spring connections in a single row of 2–24 poles. Orange buttons provide access to the wire clamps. Choose a plain body, end fixing screws or locking levers according to the required mechanical arrangement.
| Model | Configuration | Pitch | Pole range |
|---|---|---|---|
| TB27-2KN/5.08 | Plain spring terminal plug | 5.08mm | 2–24 |
| TB27-2KNM/5.08 | Spring terminal plug with end fixing screws | ||
| TB27-2KNG/5.08 | Spring terminal plug with end locking levers |
Use the complete model code when selecting the fixing arrangement. Matching pitch alone does not establish compatibility with a header.
