## Horizon Fitness 7.0AT Treadmill Digital Speed Sensor Set

The Horizon Fitness 7.0AT Treadmill Digital Speed Sensor Set is a preowned replacement sensor assembly for the Horizon Fitness 7.0AT treadmill. It helps the treadmill detect and report belt speed during operation, making it an important part of the machine’s speed-sensing system. If your treadmill displays an incorrect speed, struggles to detect belt movement, or shows symptoms linked to a faulty digital speed sensor, replacing the original sensor set may help restore proper operation.
