The 2KDH family provides straight-through spring connections in two rows at 5.08mm pitch. Each wiring point has an actuator button. Choose plain ends, fixing screws or side latches to suit the mating arrangement. Each row has 2–24 contacts, giving 4–48 contacts in total.
| Model | Series code | Pitch | Rows | Retention arrangement | Fixing torque |
|---|---|---|---|---|---|
| 2KDH/5.08 | TB31 | 5.08mm | 2 | Plain ends | Not applicable |
| 2KDHM/5.08 | M2.5 fixing screws at both ends | 0.4N·m | |||
| 2KDHG/5.08 | Left and right side latches | Not applicable |
The fixing screws on 2KDHM secure the connector; conductor termination remains a spring connection.
