## Pro-Form iSeries 660 Treadmill RPM Speed Sensor

The Pro-Form iSeries 660 PFTL57507.0 Treadmill RPM Speed Sensor is a replacement sensor for the treadmill’s speed-monitoring system. Also identified by part number and SKU **SS275**, this component helps the treadmill monitor rotational speed during operation. If your Pro-Form treadmill has a faulty, damaged, or missing RPM sensor, replacing the sensor with the correct model-specific part can help restore accurate speed detection.

Product Details and Benefits

This product is a **treadmill RPM speed sensor** made for use with the Pro-Form iSeries 660 treadmill. The sensor supports the treadmill’s internal speed-sensing function by detecting rotational movement and sending speed information to the equipment’s control system.

A working speed sensor is important because the treadmill relies on speed feedback while the motor and belt operate. When the original sensor stops working, the treadmill may not read speed correctly or may show inconsistent speed-related operation. Replacing the sensor provides the appropriate component for the equipment listed below, helping you address a speed-sensing issue without replacing the entire treadmill.

Compatibility and Applications

The **SS275 RPM speed sensor is a replacement part for the Pro-Form iSeries 660 treadmill, model PFTL57507.0**. It is intended to replace the treadmill’s original RPM or speed sensor when that component no longer functions properly or requires replacement.

Use this part for repair work involving the speed-sensing system on the specified Pro-Form treadmill. It may be suitable for treadmill maintenance, equipment repair, or restoration when the original sensor has the same part number or when the treadmill model matches the listing exactly.

Because treadmill parts can vary between model versions, confirm your equipment information before ordering. The model number **PFTL57507.0** should match the identification information on your treadmill or its original documentation.

Choosing the correct model-specific sensor helps reduce the risk of ordering an incompatible treadmill part. The SS275 provides a direct replacement option for the RPM speed sensor listed for the Pro-Form iSeries 660. Replacing only the failed sensor can also be a practical repair step when the rest of the treadmill remains in usable condition.

Before You Buy

Check that your treadmill is a **Pro-Form iSeries 660** with model number **PFTL57507.0**. Compare the original component and part number where possible, and confirm that **SS275** matches your replacement requirement. If your treadmill has a different model number or uses another sensor part number, this product may not be the correct match.
