Sec 1: Preface

Thank you for purchasing the MinebeaMitsumi Torque Transducer.
First, please make sure that the equipment has not been damaged during shipping and 
that the model is the one ordered.
If there are any problems, contact the Minebea sales office or dealer from 
which you purchased the product.
Verify the individual model specifications by using the catalog or specifications.

Sec 2: Introduction

This equipment is capable of measuring both static and dynamic torque by using a thin-flange, 
bearing-free torque transducer combining a torque detector flange calibrated by attaching 
a strain gauge and an optical transformer that acquires a signal optically, 
without making contact with the rotor.
Features include high precision, high stiffness, improved fatigue resistance, 
and improved long-term consistency. The stator (antenna unit) has a split configuration
to facilitate mounting and detachment.

CAUTION

Be sure to use the equipment within its rated operating capacity range.


Mount the equipment by hex socket head bolts.
The bolt sizes used are indicated in this manual and in the specifications manual.
Select bolts with a JIS B 1051 strength classification of at least 12.9.

In environments where the bolts are susceptible to coming loose, either make sure 
the bolts are retightened periodically or include appropriate locking precautions.

If the equipment is mounted on medical equipment or other devices with 
implications for human life, make sure protective circuits are installed in case 
the equipment stops functioning.

Contact Minebea before attempting to use in special environments.

CAUTION

Do not apply voltages to the input terminals exceeding the maximum excitation voltage.
