  • Page 2 New concepts in design driving toward greater safety and higher productivity The high level of resistance to disturbance from extraneous light that was a basic feature of the SF4-A series has been maintained in this new series, but a variety of new concepts have been incorporated into the new series, including more compact machine tool size due to a reduction in the safety distance, muting control circuits which have been built into the light curtain, and an override function that allows the manufacturing line to restart operation after the line has stopped even while muting control was active.
