\## Horizon Fitness DT650 Treadmill RPM Speed Sensor (SS336)

The Horizon Fitness DT650 Treadmill RPM Speed Sensor is a replacement treadmill sensor designed to monitor rotational speed during equipment operation. It helps the treadmill detect RPM, making it an important part of the speed-sensing system. If the original sensor has failed or needs replacement, this part may help restore the correct sensing function on a compatible Horizon Fitness DT650 treadmill.

## Product Details and Benefits

This product is a treadmill RPM speed sensor for the Horizon Fitness DT650 model. The sensor’s role is to detect rotational movement and provide speed-related information to the treadmill’s control system. Accurate speed detection supports the normal operation of the treadmill and helps the machine respond correctly while in use.

The part is identified as \*\*SS336\*\*, which appears as both the SKU and barcode for this product. Using the correct part number helps reduce confusion when replacing a small electronic or mechanical component. It also gives you a clear reference for comparing the replacement with the part currently installed on your treadmill.

The sensor is intended for replacement use rather than general-purpose applications. It is supplied as an individual treadmill sensor, and the product listing does not provide additional details about packaging quantity, dimensions, material, color, warranty, or included installation hardware.

## Compatibility and Applications

The \*\*Horizon Fitness DT650 Treadmill RPM Speed Sensor (SS336)\*\* is designed for the \*\*Horizon Fitness DT650 treadmill\*\*. It replaces the treadmill’s RPM speed-sensing component and is intended for use within the DT650 speed detection system.

This part may suit treadmill owners, fitness equipment repair technicians, and service professionals who need to replace the RPM sensor on a compatible Horizon Fitness DT650 unit. Because treadmill parts can vary by model and production version, confirm that your machine is specifically identified as a Horizon Fitness DT650 before ordering.

The product information also includes the reference \*\*TM165-1US5061855\*\*. Use this reference only if it matches the identification information for your equipment or existing part.

\## Why Choose This Replacement Sensor

Choosing a replacement sensor with the correct model and part number can make parts identification easier and help avoid ordering an unrelated treadmill component. The SS336 provides a direct product reference for buyers searching for a Horizon Fitness DT650 RPM sensor, treadmill speed sensor, or replacement speed-detection part.

Replacing the correct sensor can help address a failed or damaged RPM-sensing component, but the treadmill should be inspected to confirm that the sensor is the cause of the problem. Other electrical, wiring, control-board, or mechanical issues may produce similar operating symptoms.
