Vacuum Pad
Vacuum Suction Cup Oval Type (-S3 spec.)
Best suitable for substrate or long work like semiconductor.
-
No copper-based metallic material is used in flow paths
-
HNBR or FKM is used for the seal rubber material. *Some products are only compatible in the flow path.
Advantages
Best suitable for substrate or long work like semiconductor.
Best suitable for substrate or long work like semiconductor.
Wide selection of pad sizes, materials and holder types.
Stroke length of spring type holder can be selected.
Conventional long stroke holder (with cover) is integrated into VPC or VPD.
Stroke:6, 10, 15 and 20mm
Conventional long stroke holder (without cover) is renewed as VPOC or VPOD.
Stroke:20, 30, 40 and 50mm
The pad holder requiring for applications of "No copper alloy" and "Low-level ozone resistance" is available.
-S3 spec.:Non copper alloy is used for metal parts and HNBR or FKM is used for seal materials.
DLC. coating type uses a special coating on the surface of the vacuum pad to prevent sticking to the workpiece.
DLC. coating type significantly improves slipperiness. Effective in reducing adsorption marks and preventing sticking of lightweight and thin workpieces.
Pad surface treatment for minimizing suction marks on workpieces is available as an option.

Detailed Safety Instructions
Warning
1.When installing the pad frame, check the configuration diagram of the oval pad, use a tool that does not damage the frame, and tighten with a torque of 0.27 to 0.33 Nm, and make sure there is no loosening.
Caution
1.The adapter for oval pad is not conductive. When using a vacuum pad made of a conductive material, take measures to allow electricity to escape directly from the pad rubber.
