3 Series LZB/LZC Model Selection Note) These graphs are made using actual data. Therefore these graphs are to be used as a reference and are not a guarantee of product s performance in any case. The graphs may change depending on the operating condition or environment. Horizontal Motion of Pressing Force Model selection condition 1) Used as a force-pressing. 0 N or greater pressing force is required. Graph 1 Load thrust (N) Horizontal Transfer Model selection condition 2) Used as a transfer. 60 N transfer thrust and 40 mm/s transfer speed are required. Load thrust (N) Graph Model selection result 1) Lead 2 mm Model selection condition 1) Lead 6 mm Lead 2 mm Model selection result 1) From Graph 1, LZB/C 3 s lead 2 is applicable. (Pressing force: 80 N) LZ 3: [Speed -Thrust] Relationship Graph Speed at the end (mm/s) Model selection result 2) From Graph 2, LZB/C s lead 6 mm and lead mm are applicable. But, speed at the end with 60 N load will be 0 mm/s for lead 6 mm and 60 mm/s for lead mm. Select a suitable product in accordance with the customer s equipment.

17 Electric Cylinder Series LZB Mounting and Moving Auto Switches (Series LDZB Only) Caution 1. Tighten the screw under the specified torque when mounting the auto switch. 2. Set the auto switch mounting band perpendicularly to cylinder tube. Correctly attached Incorrectly attached Mounting the Auto Switch 1. Attach a switch bracket to the switch holder. (Fit the switch bracket to the switch holder.) 2. Mount an auto switch mounting band to the cylinder tube. 3. Set the switch holder (1.) between the reinforcing plates of the band mounted to the cylinder. 4. Insert an auto switch mounting screw in the hole of the reinforcing plate through the auto switch holder, and thread it into the other plate. Tighten the screw temporarily.. Remove the set screw attached to the auto switch. 6. Attach a switch spacer to the auto switch. 7. Insert the auto switch with the switch spacer from the back of the switch holder. (Insert the auto switch with an angle of approximately to 1. See figure 1.) 8. To secure the auto switch, tighten the switch mounting screw with the specified torque (0.8 N m to 1.0 N m). Adjusting the Auto Switch Position 1. Unloosen the auto switch mounting screw 3 turns to adjust the auto switch set position. 2. Tighten the auto switch mounting screw as described above (8.) after adjustment. Removing the Auto Switch 1. Remove the auto switch mounting screw from the switch holder. 2. Move the auto switch back towards the position where it stops at the lead wire side. 3. Hold up the lead wire side of the auto switch at the angle of around Maintain the angle, and pull back the auto switch obliquely at the same angle.

18 Series LZB Specific Product Precautions Be sure to read before handling. Refer to front matters 30 and 31 for Safety Instructions, and pages 482 to 490 for Electric Actuators/Cylinders and Auto Switches Precautions. Caution 1. Mount the auto switches at the center of the operating range. Check ON and OFF points before setting auto switches so that positions can be detected at the center of the operating range. If mounted at the end of the operating range, the signal detection will be unstable. 2. Be aware of the environment temperature and thermal cycle. Operate auto switches and auto switch cylinders within the operating temperature range. The reliability of the auto switches may be adversely affected, especially, when they are exposed to thermal shock, severe temperature and humidity cycle etc. 3. Be aware of the suitability of oil, chemicals etc. Resin and rubber materials are used for the auto switches and auto switch mounting brackets. Therefore, if there are chemicals such as oil or organic solvents in the environment, the resin and rubber materials may be adversely affected. 4. During maintenance, securely tighten the switch mounting screws periodically. Use auto switch mounting brackets with the proper tightening torque. In addition, securely tighten the auto switch mounting screws periodically.. Be careful not to pull or strain the lead wires. Be careful not to apply excess tensile force (over N) to the auto switches. Also, adjust the position of the auto switches by sufficiently loosening the auto switch mounting screws (3 turns or more). 6. Do not use the auto switches in environments with strong vibration and impact. Do not use the auto switches in environments where excess vibration and impact force outside of the specifications are applied. 7. Be sure to use a switch spacer and a switch bracket. Confirm that a switch spacer is mounted to the end of the auto switch before fastening the auto switch. If the switch bracket is not mounted, the auto switch may move after installation. 992
