Product details

0.156" Pitch, 6-Position Header with Friction Lock

It carries 6 positions on a single row at 0.156" (3.96mm) pitch, with 5 positions loaded — the unloaded position acts as a keying feature to prevent mis-mating. The friction lock provides positive retention against the mating housing, a practical advantage in environments where vibration or cable strain could otherwise separate the connection.

Tin-Plated Contacts, Through-Hole Termination

The square male pins are 0.400" (10.16mm) long on the mating side and 0.125" (3.18mm) on the post side, with an overall contact length of 0.650" (16.51mm).
