* The maximum amount of torque generated when a stepping motor is excited by its rated current.

** A comparison between our current model 103H5208-0440 and new model SF2422-12U41.

Holding torque* has been increased approximately by 10% compared with

our current model.**

This enables precise positioning and thereby shortens positioning time as well.

These motors have noise levels approximately 3 dB(A) lower than the current model.**

Motor efﬁciency has been improved by 2.4% compared with the current model.**

This contributes to reducing power consumption of devices and the motors’

heat dissipation.
