## Spirit Fitness XT600 Treadmill RPM Speed Sensor SS401
The Spirit Fitness XT600 Treadmill RPM Speed Sensor (SS401) is a replacement treadmill sensor designed for the Spirit Fitness XT600. It supports the treadmill’s RPM and speed-sensing system, helping the equipment detect the movement of the running belt or related rotating components. If your XT600 displays an incorrect speed, loses speed feedback, or needs a replacement sensor, this preowned SS401 part may provide the correct replacement option.
Product Details and Benefits
This product belongs to the treadmill sensor category and carries the model and part number **SS401**. Spirit Fitness designed the component for use with its XT600 treadmill. As a replacement part, it helps restore the sensor function required for the treadmill’s speed-monitoring system.
The part is **preowned** and has been carefully inspected by skilled technicians before sale. This inspection helps confirm the part’s condition and supports safe, reliable use when installed in a compatible treadmill. Replacing an individual sensor can also help extend the service life of an existing machine instead of replacing the entire treadmill.
The product listing identifies this item as the **Spirit Fitness XT600 Treadmill RPM Speed Sensor**. Its SKU is **SS401**, and the listed barcode is also **SS401**. The product page does not provide dimensions, material details, color, electrical specifications, or package contents, so buyers should use the part number and equipment model as the primary identification details.
Compatibility and Applications
The SS401 is a replacement RPM speed sensor for the **Spirit Fitness XT600 treadmill**. It is intended for repair or maintenance work when the original speed sensor requires replacement. The sensor may suit a treadmill that shows speed-related errors or no longer receives accurate RPM feedback, but the underlying fault should be confirmed before ordering.
Compatibility information is limited to the Spirit Fitness XT600 listed on the product page. Do not assume that this part fits other Spirit Fitness treadmill models or equipment from other brands. Compare the original component, part number, and treadmill model before purchase. If your machine has a serial-number-specific configuration, confirm compatibility with the seller before ordering.
## Why Choose This Replacement Part?
Choosing a preowned treadmill sensor can reduce repair costs compared with purchasing a new assembly or replacing a larger component. Reusing an inspected fitness part also helps extend the useful life of existing equipment and reduces unnecessary waste. This option may suit home users, fitness equipment technicians, and service providers repairing a Spirit Fitness XT600 treadmill.
The part has been checked by technicians, but it remains a used component and may show signs of previous installation or handling. The product page states that photographs are for reference because the seller carries multiple units. The item shipped will match the listed model and part.
