17 Series Specific Product Precautions Be sure to read before handling. Refer to front matters 2 and 3 for Safety Instructions and pages 3 to for Actuator and Auto Switch Precautions. Caution on Handling Auto Switches When installing in close proximity to each other Caution. When compact slide cylinders equipped with D-A9 or D-M9 auto switches are used, the auto switches could activate unintentionally if the installed distance is less than the dimension shown in Table (). Therefore, make sure to provide at least this much clearance. Due to unavoidable circumstances, if they must be used with less distance than the dimensions given in the table below, the cylinders must be shielded. Therefore, affix a steel plate or a magnetic shielding plate (MU-S) to the area on the cylinder that corresponds to the adjacent auto switch. (Please contact SMC for details.) The auto switch could activate unintentionally if a shielding plate is not used. Table () Bore size (mm) Dimensions of shielding plate (MU-S) that is sold separately are indicated as reference. Material: Ferrite stainless steel, Thickness:.3 mm Since the back side is treated with adhesive, it is possible to attach to the cylinder. Operating Precautions Caution d 3 (mm) L Do not place your fingers in the clearance between the non-rotating plate and the cylinder tube. Your fingers could get caught between the table and the cylinder tube when the piston rod retracts. If fingers are caught in a cylinder, there is a danger of injury due to the strong cylinder output, and therefore caution must be exercised. 2. In terms of the load mass and moment, the cylinder must be operated below the maximum load mass and allowable moment. 3. If the output of the compact slide is applied directly to the table, make sure it is applied along the rod axial line. (Refer to the figure below.) 8 d L Operating Direction with Different Pressure Ports Caution. The compact slide can be mounted in three directions. Check the pressure port and the operating direction. (Refer to the figure below.) OUT OUT port (On both sides) IN port (On both sides) Stroke Direction Backlash Caution Since the connection between the piston rod and table is a floating structure, there is a maximum table backlash of. mm in the stroke direction. (Refer to the figure below.) IN IN port When customers change the port location, please order the plugs listed below. Replacement plug part no.: CXS A Table Max.. mm Piston rod Piston rod and table connection OUT port. Make sure to connect a speed controller and adjust it to a speed of mm/s or less to operate the cylinder. 3 D- -X -X

18 Series Specific Product Precautions 2 Be sure to read before handling. Refer to front matters 2 and 3 for Safety Instructions and pages 3 to for Actuator and Auto Switch Precautions. Caution Mounting. When tightening threads for compact slide, properly tighten within the specified torque. How to Mount a Compact Slide A compact slide can be mounted from directions. Make a selection suitable for the applicable machinery and workpieces, etc. Lateral Mounting (Body through-hole) Lateral Mounting (Body tapped) Model Bolt M3 x.

19 Series Specific Product Precautions 3 Be sure to read before handling. Refer to front matters 2 and 3 for Safety Instructions and pages 3 to for Actuator and Auto Switch Precautions. Caution Front Mounting Mounting. When tightening threads for compact slide, properly tighten within the specified torque. 2. When mounting a workpiece on the top of the table, do not screw a bolt in more deeper than the female thread (Below table l dimension). If screwing a bolt in more deeper than the l dimension, the edge of the bolt could reach the linear guide and might damage the linear guide. How to Mount a Workpiece A compact slide can be mounted from 2 directions. Make a selection suitable for the applicable machinery and workpieces, etc. Top Mounting Model Bolt M3 x. M x.7 M x.7 M x.8 Maximum tightening torque (N m) l. 7. Model Bolt M3 x. M x.7 M x.7 M x.8 Maximum tightening torque (N m) l How to Mount a Workpiece Workpieces can be mounted on 2 surfaces of the compact slide. Since the table is supported by the linear guide, take care not to apply strong impact or large moment, etc. when mounting workpieces. Hold the table when fastening workpieces to it with bolts, etc. If the body is held while tightening bolts, etc., the guide section will be subjected to a large moment, and there may be a loss of precision. D- For connection with a load having an external support/guide mechanism, select an appropriate connection method and perform careful alignment. Use caution, as scratches or nicks, etc. on the sliding parts of the piston rod can cause malfunction and air leakage. -X -X 33
