1 IFORMTIO Vacuum ad with Ejector ad Diameter: ø63, ø8 RoHS Ejector and pad are integrated. Space saving and reduced piping labor! Bellows type with groove Two-stage ejector More efficient ejector Suction flow rate 5% increased 1 1) Compared with SMC single stage ejector Two-stage ejector First ejector Second ejector ir consumption 3% reduced 1 Flat type with groove Q1 + Q2 = Suction flow rate With One-touch fitting Metric: ø4, ø6 Inch: ø5/32", ø1/4" Strainer revents entry of foreign matter at the pad suction port. Improved ease of removal 2 With groove Dents and bumps on the adsorption surface prevent the workpiece from sticking to it. This facilitates easy removal. SU EXH Silencer Through-hole silencer The exhaust is discharged directly to atmosphere, cutting off the unpleasant frequency while exhibiting the maximum possible vacuum performance. Low noise: 6 db() (Exhaust noise when the nozzle diameter is ø.7) Structure designed to minimize clogging ort/for Vacuum release, ressure sensor, Daisy-chain piping Daisy-chain vacuum piping is possible. <Daisy-chain piping example> Shot-blasted Micro-dents and bumps are formed on the adsorption surface. Workpieces can be removed easily. 2 Compared with current Z series With ejector Without ejector Daisy-chain piping Series ZH 14-E632

Recommended Work Load [] ZH63 ZH8 Horizontal lifting Vertical lifting Use this product with the recommended work load or less. The transfer work over the recommended work load may cause the vacuum pressure to decrease by the air leak. The work load shown above is the value when the vacuum pressure reaches 85 ka, and that is calculated by multiplying the theoretical value by a safety factor of 1/4 for the horizontal lifting or 1/8 for the vertical lifting. For details, refer to the Vacuum Equipment Model Selection in the Best neumatics o. 4 catalog. The vacuum pressure reached may vary depending on the workpiece (permeability, etc.) Calculate the actual work load in accordance with the vacuum pressure reached.

7 Series ZH Specific roduct recautions 1 Be sure to read this before handling. For Safety Instructions and Vacuum Equipment recautions, refer to Handling recautions for SMC roducts and the Operation Manual on SMC website, 1. Use the product while strictly observing the precautions on vacuum equipment and taking the safety into consideration. dditionally, select a pad size and material suitable for the workpiece to be adsorbed and the atmosphere. Take safety measures so that any accident, such as workpiece drop does not occur during adsorption transfer. For details, refer to the Best neumatics o. 4 catalog. 2. fter the pad has been replaced, lock the lock plate completely before use. (Refer to q shown in the figure below.) If the lock plate is not locked completely, the pad may drop due to the vibration or load during operation. 3. To ensure the safety, be sure to mount the lock screw on the lock plate before use. (Refer to w shown in the figure below.) If the lock plate comes off during operation, this may cause a serious accident, such as pad drop or workpiece drop. 6. Replace the pad while referring to the figure below.

If the adsorption time delay or incorrect adsorption occurs, the vacuum leak due to worn out pad or strainer clogging may be the cause. erform the periodic maintenance so that any trouble such as workpiece drop does not occur. 5. When connecting multiple pads to one ejector through the vacuum communication, other pads also cannot adsorb if incorrect adsorption occurs in one pad. Take safety measures so that the workpiece does not drop during transfer. q Remove the lock screw. w ush the lever (on the ejector side) of the lock plate to slide it to a position where it stops completely. e ull out the pad assembly. r ull out the stud assembly from the pad assembly. t Remove the holder. y Remove the plate from the pad. u Mount the pad in the reverse order of steps above. Cautions on pad mounting When mounting the pad assembly on the adapter plate, adjust the position so that the non-rotating convex part on the bottom of the adapter plate enters the non-rotating hole in the holder. dapter plate on-rotating convex part When locking the lock plate, push in the stud assembly from the lower portion. If the stud assembly is not p u s h e d i n t o t h e a d a p t e r p l a t e completely, the lock plate slides insufficiently, causing pad drop or vacuum leak. Stud 7. Recommended One-touch fitting to be mounted at the D port is the KQ2S6-1lS or KQ2S7-34lS. One-touch fitting may interfere with the top surface of the pad depending on the fitting dimensions. This may cause the One-touch fitting not to be mounted. 6

8 Series ZH Specific roduct recautions 2 Be sure to read this before handling. For Safety Instructions and Vacuum Equipment recautions, refer to Handling recautions for SMC roducts and the Operation Manual on SMC website, 8. When supplying the vacuum release air to the D port, select an appropriate product suitable for the specifications so that the R port of the 2 port or 3 port valve to be used is blocked not to leak the vacuum in the closed state. 9. When using the male thread mounting type product, do not loosen the bottom nut shown in the figure below. (The bottom nut is intended to secure the connection between the bracket for the adapter connection and the male thread.) Do not loosen this nut. Male thread dapter connection bracket 11.
