• For universal use in clean to slightly dirty working environments, especially suitable for gripping small workpieces
• T-slot guidance for precise gripping at high-moment loads
• Finger position monitoring also possible via FPS
• Air supply via hose-free direct connection or screw connections for flexible pressure supply in all automated systems
• Compact dimensions for minimal interfering contours in handling
• Sizes Quantity: 6
• Weight: 0.01 .. 0.29 kg
• Gripping force: 20 .. 310 N
• Stroke per jaw: 1 .. 5 mm
• Workpiece weight: 0.05 .. 1.15 kg

Product Usage Instructions

• The gripper is pneumatically driven and moves the piston up and down using compressed air.
• The angled active surfaces of the wedge hook produce a synchronized, centric jaw movement.

General Notes:

• Finger length is measured from the reference surface as the distance P in the direction of the main axis. The maximum permissible finger length applies until the nominal operating pressure is achieved. With higher pressures, the finger length must be reduced proportionally to the nominal operating pressure.
• Repeat accuracy is defined as the distribution of the end position for 100 consecutive strokes.
• Workpiece weight is calculated for force-fit gripping with a coefficient of static friction of 0.1 and a safety factor of 2 against workpiece slippage at acceleration due to gravity g. For form-fit or capture gripping, there are significantly higher permissible workpiece weights.
• Closing and opening times are purely the times that the base jaws or fingers are in motion. Valve switching times, hose fill times, or PLC reaction times are not included and should be considered when calculating cycle times.

Application Example:
Pneumatically driven 2-axis line gantry with centric gripper for gripping and repositioning small round workpieces.

Functional description

The piston is moved up and down by compressed air. The angled active surfaces of the wedge-hook produce a synchronized, centric jaw movement.

1. T-slot guidance for precise gripping with high-moment loads
2. Wedge-hook design for high-force transmission and centric gripping
3. Housing is weight-optimized due to the use of high-strength aluminum alloy
4. Drive pneumatic, efficient, and easy to handle

General notes about the series

• Operating principle: Wedge-hook kinematics

• Housing material: Aluminum alloy, anodized

• Base jaw material: Steel

• Actuation: pneumatic, with filtered compressed air as per ISO 8573-1:2010 [7:4:4].

• Warranty: 24 months

• Scope of delivery: Centering sleeves, centering pins,

• O-rings for direct connection, assembly instructions (operating manual with declaration of incorporation is available online)

• Gripping force maintenance device: possible by using the version with mechanical gripping force maintenance or pressure maintenance valve SDV-P
  Gripping force: is the arithmetic sum of the individual force applied to each jaw at distance P (see illustration).

• Finger length: is measured from the reference surface as the distance P in direction to the main axis.

• The maximum permissible finger length applies until the nominal operating pressure is achieved. With higher pressures, the finger length must be reduced proportionally to the nominal operating pressure.

• Repeat accuracy: is defined as a distribution of the end Position for 100 consecutive strokes.

• Workpiece weight: is calculated for force-fit gripping with a coefficient of static friction of 0.1 and a safety factor of 2 against workpiece slippage at acceleration due to gravity g. For form-fit or capture gripping, there are significantly higher permissible workpiece weights.

• Closing and opening times: are purely the times that the base jaws or fingers are in motion. Valve switching times, hose fill times, or PLC reaction times are not included and are to be considered when cycle times are calculated.

The following components make the product even more productive – the suitable addition for the highest functionality, flexibility, reliability, and controlled production.

For more information on these products can be found on the following product pages or at schunk.com.

Options and special information

Gripping force maintenance version AS/IS: The mechanical gripping force maintenance version ensures minimum gripping force even in the event of a pressure drop. In the AS/S version this acts as a closing force, in the IS version as an opening force.
Version FPS for flexible position sensor: This version is prepared for the use with the flexible position sensor FPS, and allows monitoring of several gripping positions.
NEW: Version with food -compliant lubrication (H1G): as a solution for an easy entry into medical technology, lab automa-tion, pharmaceutical and food industry. The requirements of EN 1672-2:2020 are not fully met.

Gripping force maintenance device AS / IS

The mechanical gripping force maintenance device ensures that a minimum clamping force will be applied even if there is a drop in pressure. This acts as a closing force in the AS / S version and as an opening force in the IS version. Besides this, the gripping force maintenance device can be used to increase the gripping force or for single-actuated gripping.

SDV-P pressure maintenance valve

• 4 Grippers
• 90 IT SDV-P pressure maintenance valve

The SDV-P pressure maintenance valve ensures in emergency STOP situations that the pressure in the piston chamber of the pneumatic gripper, swivel, linear, and quick-change modules is temporarily maintained.

SDV-P 04-E| 0300120| 6

NOTE
In order to achieve the specified closing and opening time for each gripper variant, the recommended hose diameter must be used. The direct allocation of the respective variant of the gripper for the respective SDV-P can be found at schunk.com.
