SLFN-668 Short Axial Dimension Disc Torque Sensor
Product Introduction
The SLFN-668 disc high-speed sensor is specially designed to meet
the requirements of high-speed torque measurement. The short axial
size disc torque sensor is a sensor for transmitting torque
parameters developed on the basis of the standard torque sensor.
This type of sensor is specially designed and manufactured to meet
the requirement of short axial size and is one of the torque
sensors with the shortest axial length. It is applicable to the
monitoring and measurement of transmission and braking components
in the automotive industry. This sensor must be specially designed
and customized according to the user's requirements. (This model
has the function of wireless signal transmission and needs to be
customized.)

Product Features
- The axial dimension is short
- High precision and sensitivity
- Fast dynamic response
- High rigidity and overload resistance capacity
- The maximum speed is 30,000 RPM
- Compact structure, convenient to install
- Non-contact measurement
- Multi-signal output and compatibility
