HiMod - Model 2SA78 - Rotary Actuators Brochure

SEVEN HiMod was developed to operate in conditions where the highest quality of control is an absolute prerequisite. Among the exceptional quality features of the SEVEN HiMod is a Highres Absolute Position encoder with a maximum tolerance of 0.003 %. By means of this encoder, the HiMod actuator registers the position of the output shaft even when there is a power failure, if the position of the output shaft is altered by operating the hand wheel. As a result, changes of position which could occur during a power-cut can be reliably identified and, when power is reinstated, this information is communicated accurately to the control system.
