The coordinate system of a terminal defines a reference system for the definition of other values (e.g. the *WireReception.Rotation*). The definition is the following (see illustration).

- The origin (0,0,0) is in the intersection point the centerline of terminal (z-axis) and the perpendicular plane through the most forward end position of the terminal in its cavity.
- The y-axis points in the direction of the primary locking.
- The x-axis is the cross product of y and z, x = y ⨯ z).

The rotation of the *WireReception* is the angle between the normal vector on base plane of the crimp area and the y-axis, which is a rotation around the z-axis (right hand rule, compare illustration).
