It is a small size stick underground marker with a pre-programmed ID number. The design of the PIN Marker provides the possibility of its detection in both vertical and horizontal positions.
For optical networks, the PIN Marker Smart 60/40 is designed so that it can be directly attached to a 7/4 mm microduct using an optical coupler. It can be attached to other diameters using reducers.
In other applications, it is ideal for marking important points at shallow depths
