| Description |
| |
Type 110-P-121 /-221 terminal block has been specially designed to allow effective potting of PC boards. The molding design prevents seepage of the potting material into the wire clamping area up to 21 mm (0.83 in.) from the board.
 | Header |
| Double level (rows on same level) |
| Plug-In Direction and Wire Entrance Perpendicular to PCB when plugged with 110-A-111, 110-A-IDC |
| 110-P-221 is equipped with a poka-yoke feature on each end sidewall. This prevents incorrect misaligned plugging when utilized with 110-A series plugs. Internal features prevent backwards insertion. |
| 110-P-121 have a small foot print that allows a "in" fit when replacing competitive product. This is especially useful on PCB that are typically completely covered in components. It can be said that misalignment would in principle be prevented by the close components in close proximity. |
| Internal features prevent backward insertions |

Coding keys 120-K are available to prevent the insertion of the wrong plug into a header. These are usually field inserted but can be factory installed if required. These coding keys are visible from the exterior, through slots in the header. Correct keying requires the removal of corresponding keying nibs from the 110-A plugs.
