SIVA – SPRINT Dumbel Foam Tag (R6P)

The SIVA SPRINT Dumbel Foam Tag (R6P) is a race timing UHF RFID foam transponder engineered for accurate athlete identification in marathons, sprints, and endurance events. Designed with an optimized antenna and foam spacer, it eliminates detuning caused by close proximity to the human body, ensuring precise read accuracy and consistent performance throughout the race.

Manufactured with Impinj Monza R6-P IC technology, this passive UHF transponder delivers superior sensitivity and reliability across global UHF frequency bands (860–960 MHz). The tag is supplied in roll form for easy integration and supports custom printing and encoding, making it a professional, ready-to-deploy solution for race organizers and RFID integrators.
