Installing the NFC antenna
The NFC antenna is suitable for installation behind a glass front as well as for mounting on the
outer surface of a vending machine door. The antenna is fixed with four M4 screws. The length
of the screws depends on the wall thickness of the vending machine door. The screws must not
penetrate deeper than
5 mm
into the threaded bushes of the NFC antenna.
A length of 8 mm should generally suffice.
The fixing screws are not included in the scope of delivery of the NFC antenna.
Appropriate holes (4x 5.5 mm and 1x 25 mm) must be drilled in the vending machine door for
the fastening screws and for the cable feed-through. Two drilling templates are available to
make this easier:
▪
KarL4 standard drilling template (Art. no. 400-2577Ra)
This template has the same outer diameters as the
antenna itself and can therefore always be used,
especially where only limited space is available for
mounting the antenna.
