RF Transponder

by TAG Heuer

The Protime RF Transponder is well suited for timing in difficult environments. It is the ideal solution for overcoming noise issues which are a common cause of failed detections for other timing systems.

The RF Transponder can be used for rental karting and other low speed motorsports.

RF transponder is activated by an active loop and uses a radio transmission with the RF decoder to recorded identification and time.

With its small dimensions, it can discreetly be placed on the vehicle or participant.

This transponder is delivered with a Lithium battery. The battery can be replaced directly by the customer when it is empty (battery type: CR2450).

An LED indicates proper operation of the transponder when it is activated by the loop.
