Design Guidelines
When integrating the VP3300 OEM into a project, make sure to follow the guidelines below.
•
MSR Head: VP3300 OEM device supports multiple MSR head types including:
o
Wing Spring
o
Leaf Spring
o
Frame Spring
o
Cantilever
•
MSR Connection:
The MSR connection must be flexible printed circuit.
•
MSR Connector Length:
The recommended FPC maximum length is 30cm.
•
Contactless Mounting:
Note that the antenna’s RF field antenna is sensitive to the proximity
of metal. There are three options for mounting the VP3300 OEM components in a metal
surface:
o
Mount with the RF emitting surface of the antenna at least 1cm
forward
of any metal.
o
Mount with the RF emitting surface of the antenna at least 1cm
behind
any metal.
This will reduce the effective range of the antenna.
o
Mount flush with the metal but allow a minimum of 1cm distance from the metal.
•
EMV Mounting: The EMV cable comes with a ferrite shield
to protect from EMF interference;
see mounting guidelines below:
