De Haardt Xtra.Sensor MK2 – Transponder Expansion Module

The Xtra.Sensor MK2 is an expansion module that plugs into any existing De Haardt shutdown transponder, adding a full suite of track management and timing functions without replacing the transponder or requiring additional power sources. No batteries — it draws power and communication directly through the transponder it's connected to.

For operations already running De Haardt shutdown transponders, the Xtra.Sensor MK2 is the most cost-effective way to upgrade to a full track management system without starting from scratch. Fit one per kart and the entire fleet gains lap timing, sector control, and pit lane management capability overnight.

The MK2 version carries the same functionality as the original Xtra.Sensor and is fully downward compatible — it works with existing De Haardt installations without requiring a system-wide upgrade.

Functions:

• Pit-in slowdown and pit-out speed up
• Lap timing
• Sector functions — controllable via De Haardt Xtra Remote Control or track management software through the Xtra.Black Box
• Power and communication via existing De Haardt transponder
• No batteries required

Version: MK2

Compatibility: All De Haardt shutdown transponders — downward compatible with previous Xtra.Sensor installations
