Type 102 (33, 35, 31)

This is a micro-sized lineup of electromagnetically operated clutches that activate when an electric current is applied to the coil. Featuring a bearing-mounted design that allows for installation without worrying about alignment or centering, the series offers three types of armature assemblies with different mounting configurations, enabling selection based on specific installation requirements.

The dynamic friction torque Td is the value at a relative speed of 100 min⁻¹. Additionally, depending on the initial torque characteristics, a break-in period may be required.
Keep fluctuations in the supply voltage within ±10% of the coil voltage. Also, ensure that the duty cycle does not exceed 80%.
The moment of inertia and mass of the rotating section are based on the values at the maximum bore diameter.
