CONTACT LAYOUT

VIEWED FROM THE FRONT FACE OF MALE INSULATOR

Note : * Insert arrangement available.4

ORIENTATION

VIEWED FROM THE FACE OF THE PIN INSERT

NOTE : 1) The position of the insert is rotated clock wise from the normal position (N) to the required angle “W” or “X” or “Y” or “Z”.

2) The different orientation is used when more than one connector with same contact layout is used. It avoids coupling of the connectors with its neighbour.
