The 2KD family provides wire-side plugs with spring connections and actuation buttons. Twelve models combine 5mm or 5.08mm pitch with standard, A or B housing configurations. M variants add screw-fixing flanges. All models have one row of 2–24 terminal positions. Match the complete housing, pitch and mating geometry when selecting a counterpart; pitch alone does not establish compatibility.

Dimensions are in millimetres. N is the pole count. Length along the terminal row is separate from the side-view body and mating dimensions.
| Model | Terminal body length | Other specified dimensions |
|---|---|---|
| TB25-2KD/5.0 | 5×N+0.70 | 15.00 body dimension in top view; 23.65 in section view; terminal span 5×(N−1) |
| TB31-2KD/5.08 | 5.08×N+0.70 | 15.00 body dimension in top view; 23.65 in section view; terminal span 5.08×(N−1) |
| TB25-2KDM/5.0 | 5×N+0.60 | Flange-inclusive length 5×(N+2); screw-centre span 5×(N+1); 25.35 overall side-view height; 23.65 main body height; 8.30 mating portion; 5.70 mating portion width; 5.80 flange dimension |
| TB31-2KDM/5.08 | 5.08×N | 15.00 body dimension in top view; 23.65 in section view; fixing centres one 5.08mm pitch outside the adjacent terminal centre; 5.80 flange dimension |
A and B versions place the latch on opposite sides of the mating portion. Both have a 26.60mm side-view length and a 16.80mm reference body dimension. Their terminal bodies and fixing flanges must be selected by the individual drawing.

The M flange dimension is 7.80mm, with the fixing-centre line 1.20mm from its upper edge in the indicated view. The mating portion is dimensioned at 5.60mm on the applicable views. TB26-2KDAM/5.0 additionally specifies a 14.80mm body reference and an 8.30mm mating portion. Use the drawings for smaller local offsets and the exact A/B latch orientation.
