## Precor 9.21, M9.23, M9.27 Treadmill Safety Key Sensor (SS28)
The Precor SS28 Safety Key Sensor is a replacement treadmill sensor designed for compatible Precor fitness equipment. It supports the treadmill’s safety key system, helping the machine recognize the key during operation. If the original sensor becomes damaged, worn, or stops responding, replacing it with the correct SS28 part can help restore the safety-key function on a compatible treadmill.
This product is listed as a Precor speed sensor and carries the part number and SKU **SS28**. It is identified for use with the following Precor treadmill models:
- Precor 9.21 treadmill
- Precor M9.23 treadmill
- Precor M9.27 treadmill
Because treadmill parts can vary by model and production version, check your existing component and treadmill model before ordering. Confirm that the original part matches the SS28 identification and that your machine appears in the compatibility list above.
Product Details and Benefits
The Precor SS28 is a treadmill safety key sensor rather than a complete safety key or console assembly. Its purpose is to work with the treadmill’s safety-key system. The sensor helps the equipment detect the key position so the treadmill can operate as intended when the key is in place.
This part may suit fitness equipment owners, repair technicians, gyms, and service providers maintaining older Precor treadmills. Installing the correct replacement component can help avoid replacing a larger assembly when only the sensor requires attention. It can also support efforts to keep an existing treadmill in service instead of discarding equipment because of a smaller failed part.
Each part has been inspected by skilled technicians for performance and safety before shipment. The item is offered as a used fitness part, so its appearance may differ from the product image. Stock may include more than one available part, and visual details can vary. However, the supplied item will be the SS28 model and the same type of part identified on this listing.
Compatibility and Applications
The SS28 Safety Key Sensor is intended for compatible **Precor 9.21, M9.23, and M9.27 treadmills**. It is used in the treadmill safety-key system and may be suitable when the original sensor no longer detects the key correctly.
Use this component only after confirming the model and part identification. Compatibility should be checked against the treadmill’s existing sensor, service information, or the part removed from the machine. This listing does not identify compatibility with other Precor models or other treadmill brands.
Why Choose This Product
The Precor SS28 provides a specific replacement option for a safety-key sensor used in select Precor treadmills. Its inspected used condition may help repair a compatible machine while reducing the need to source a complete console or treadmill assembly. Reusing fitness equipment parts also helps extend the service life of existing equipment and reduce unnecessary waste.
