\# Xterra TRX3500 Treadmill RPM Speed Sensor (SS139)

The Xterra TRX3500 Treadmill RPM Speed Sensor is a replacement treadmill sensor designed for the Xterra TRX3500.

## Product Details and Benefits

This product belongs to the treadmill sensor category and carries the product name \*\*Xterra TRX3500 Treadmill RPM Speed Sensor\*\*. The product SKU and barcode are \*\*SS139\*\*. Its primary purpose is to sense the treadmill’s rotational speed so the equipment can receive the speed information required by its control system.

A working RPM speed sensor plays an important role in the treadmill’s speed-monitoring system. When the original sensor needs replacement, using a part identified for the correct treadmill model can help simplify the repair process and support proper component matching. The SS139 sensor provides a model-specific replacement option for the Xterra TRX3500 rather than a general-purpose treadmill sensor.

The product information identifies this item as an Xterra Fitness component. Its listed product name clearly defines its application: it is an RPM and speed sensor for a treadmill, not a belt, motor, control board, or console. This distinction helps buyers select the correct type of replacement part when servicing their equipment.
