Cable Connection Procedure
The unit shown in the figure is the NNN-21, which is almost identical to the NNN-31.
Installing the clamp filter or connecting the extension cable requires a self-bonding tape
and vinyl tape. Apply RTV rubber or silicone rubber to waterproof the sensor unit.
1. Install clamp filters (one large and one small) to the antenna side of the included cable. Roll
the cable once around the large clamp filter. Also install a clamp filter (small) to the display
side. (Refer to the following figures.)
NOTE1: Determine the installation position of the clamp filter (large) by considering the
installation condition of the sensor. (Refer to the installation figure on page 2-7.)
2. Processing
Clamp Filter
2.1 Roll up a self bonding tape around the clamp filters in the antenna side. (No need to roll up
the one in the display side.)
Roll up the tape by pulling so that the tape will be lengthened by two times. Also, roll up
the tape so that the half of it is overlapped. Repeat three times to make it three-layered.
After rolling up, press the tape with the fingers for secure attachment.
2.2 Wrap by a vinyl tape for protection.
Do not put tensile force to the vinyl tape as much as possible. Roll up the vinyl tape so that
the half of it is overlapped. Repeat three times to make it three-layered.
Crimp the end of the rolled tape without tension. Press the whole tape with the fingers for
secure attachment
