3. 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
