Robust interior multiple-tooth guidancefor the precise handling of all kinds of workpieces
Wiper seal on the outer round guidefor permanent, secure gripper sealing
High maximum momentssuitable for the use of long gripper fingers
Sealed 2-finger parallel gripperis conform to IP67 requirements despite high moment-load capabilities
Oval piston drive designfor maximum gripping forces
Mounting from two sides in three screw directionsfor universal and flexible gripper assembly
Air supply via hose-free direct connection or fittingconnectionsfor the flexible supply of compressed air in all automation systems
Compact dimensionsfor minimal interfering contours in handling
Despite the high moment load capabilities of the base jaws, this sealed 2-finger parallel gripper conforms to the IP 67 requirementsand does not permit any substances from the working environment to penetrate the interior of the unit.
Sealed Grippers
Area of applicationThe DPG-plus is ideally suited for the handling of rough or dirtyworkpieces. Its area of application extends from the loading andunloading of machines, such as in the case of sanitary blocks,grinding machines, lathes or milling machines, to handling tasks inpainting plants, in powder-processing and underwater.

General information on the seriesWorking principleWedge-hook kinematics
Housing materialAluminum alloy, hard-anodized
Base jaw materialHardened steel
ActuationPneumatic, with filtered compressed air (10 µm): Dry, lubricated or non-lubricatedPressure medium: Required quality class of compressed air according to DIN ISO8573-1: Quality class 4
Warranty24 months
Scope of deliveryCentering sleeves, O-rings for direct connection, assembly and operating manual with manufacturer’s declaration
Gripping force safety devicewith either mechanical gripping force safety device or SDV-P pressure maintenancevalve
Inner base jaw (multiple-tooth guidance)for heavy moment loads
Outer base jaw (round)providing a sealable, round surface
Wiper sealfor permanent, secure gripper sealing
Oval piston with rod and wedgehookfor power generation and transmission
The piston is moved up or down by means of compressed air. The angled active surfaces of the wedge hook produce a synchronized, parallel jaw movement.
Function descriptionPlease note that an additional hose for bleeding or purging the air is essential for thegripper, i.e. it requires three hoses in total. See the assembly and operating manualfor more detailed information.
Version with higher grip forces When higher gripping forces are required
Gripping forceis the arithmetic total of the gripping force applied to each base jaw at distance P(see illustration), measured from the upper edge of the gripper.
Finger lengthis measured from the upper edge of the gripper housing in the direction of the mainaxis.
Repeat accuracyis defined as the spread of the limit position after 100 consecutive strokes.
Workpiece weightThe recommended workpiece weight is calculated for a force-type connection with a coefficient of friction of 0.1 and a safety factor of 2 against slippage of the work-piece on acceleration due to gravity g. Considerably heavier workpiece weights arepermitted with form-fit gripping.
Closing and opening timesClosing and opening times are purely the times that the base jaws or fingers are inmotion. Valve switching times, hose filling times or PLC reaction times are notincluded in the above times and must be taken into consideration when determiningcycle times.

Technical data
Finger load
Moments and forces apply per base jaw and may occursimultaneously. My may arise in addition to the momentgenerated by the gripping force itself. If the max.permitted finger weight is exceeded, it is imperative tothrottle the air pressure so that the jaw movement occurswithout any hitting or bouncing. Service life may be reduced.
The mechanical gripping force safety device ensures a minimum gripping force even ifthere is a drop in pressure. This acts as closing force in the AS version, and as openingforce in the IS version. In addition, the gripping force safety device can also be employedas a gripping force booster or for single-acting gripping.
�� Projection only with AS version
The direct connection is used for supplying compressed air to the gripper withoutvulnerable hoses. Instead, the pressure medium is fed through bore-holes in the mounting plate.

For finger connection, we recommend only using two of the four centering bores foreach finger. The drawing shows the gripper in the basic version with closed jaws, thedimensions do not include the options described below.

The SDV-P pressure maintenance valve can also be used (see “Accessories”catalog section) for I.D. or O.D. gripping as an alternative or in addition to thespring-loaded, mechanical gripping force safety device.
The KVZ grip force cylinder increases the gripping forces during opening and closing.A second, in series-connected piston also increases the force on the wedge hook. The fullgripping force shown in the data table is sometimes only reached after a few hundredgripping cycles.
