T2000SFL
Transponder

Smaller. Lighter. Just as Reliable.

* Suitable for Light Sports and Experimental Aircraft

The T2000SFL is one of the world’s smallest and lightest certified Mode 3A/C transponders, weighing just 600g. With over 5,000 units still in operation globally, it’s a trusted solution for certified aircraft where space, weight and efficiency are key.

Despite its size, the T2000SFL delivers low power consumption and advanced safety features typically found in larger, more costly systems.

Certified to TSO C-74C, it integrates easily with any C88a-compliant altitude encoder, including the Microair EC2002.
