H-3HABSOLUTE Digimatic Scale UnitsDesigned to capture positional coordinates from slides on machine tools and precision instruments including semiconductor production equipmentMitutoyo operates a policy of continuous improvement that aims to provide the customer with the benet of the latest technological advances.Therefore the company reserves the right to change any or all aspects of any product specication without notice.SD ABSOLUTE Digimatic Scale UnitsSERIES 572 ApplicationsMachine table positionDrilling machine stroke positionFocus setting on optical instruments•SD series facilitates mounting on jigs, tools, and small machine tools to enable accurate positioning.•Built-in absolute scale including the ABS point requires no zero-set every time the power is turned on.In addition, reliability has improved thanks to elimination of overspeed errors.•Horizontal or vertical display according to the scale mounting direction.•The dust resistance and the environmental resistance of the display has improved. The SD-G series offers dust/water protection level IP66.•Long battery life for easier maintenance.•EC counters are available as external display units.•Equipped with an output port to transfer measurement data. This allows implementation in control systems and gaging systems.Functions• ABS (Absolute) measurement function• INC (Incremental) measurement function• Zero-setting function• Presetting function (2 preset values can be set. Not available for SD-G, SD-D, SDV-D) • Double reading function (Available only for SD-F or SDV-F)• Direction switch functionNot available for SD-G, SD-D, SDV-D, SD-F, SDV-F)• Hold function*• Measurement value composition error alarm• Low battery alarm• Output function* To activate the hold function when using SD-D or SDV-D, an optional hold unit is required. Simultaneous activation with the output function is not available.SD-G are also available to special order.* These units use 1.5V silver oxide cells for the power supply. Therefore, when the units are directly xed to the frame of a machine tool that requires a high voltage, malfunction such as display digit uctuations and errors may occur. The countermeasure examples are described in the user manuals provided.Please contact Mitutoyo for other special orders.Detector head mechanismSpecial applicationsRefer to the ABSOLUTE DIGIMATIC SCALE UNITS (Catalog No.E4316) for more details.Horizontal single-function type572-202-20 SD-20DXHorizontal single-function type (Water-proof type)572-602 SD-20GHorizontal multi-function type572-461 SD-15EVertical multi-function type572-561 SDV-15EVertical single-function type572-303-10 SDV-30DAs a measurement jig for outdoor use (SD-G)(Refer to page X for details.)
