3Product Description
3.1 Operating Principle of The Area Gripper
The area gripper is usually connected to a gantry or robot, which makes it possible to lift and move loads.
FXP-i Version
The integrated ejector generates the vacuum required for this purpose. The vacuum keeps the load attached to the
area gripper.
FMP-i Version
On the version for external vacuum generators, the vacuum, which is provided by a blower, is switched on and off as
required by the integrated valve.
3.2 Picking up the Load
FXP-i Version
The venturi nozzle on the ejector is activated and deactivated using the suction command:
•In the NO (normally open) variant, the venturi nozzle is deactivated when the Suction signal is received.
•In the NC (normally closed) variant, the venturi nozzle is activated when the suction signal is received.
An integrated sensor records the vacuum generated by the venturi nozzle. The exact vacuum level is shown on the
display and can be read from the IO-Link process data.
The diagram below shows the vacuum curve for when the air saving function is activated:
The integrated ejector has an air saving function and can control the vacuum automatically when the control function
is activated in suction mode:
•The electronics switch the venturi nozzle off as soon as the vacuum limit value set for switching point SP1 is
reached.
•When objects with airtight surfaces are picked up, the integrated non-return valve prevents the vacuum from
dropping.
•If leakages cause the system vacuum to drop below the limit value configured for the switching point rP1, the
venturi nozzle is switched back on.
•The OUT output is set once a workpiece is picked up securely, based on the vacuum value. This enables the
further handling process.

Product Description
12 / 96 EN · 30.30.01.02851 · 01 · 03/22
FMP-i Version
On the version for external vacuum generators, the valve is opened using the suction command. This ensures that the
vacuum reaches the inside of the gripper so that products can be lifted.
•In the NO (normally open) variant, the valve is closed when the suction signal is received.
•In the NC (normally closed) variant, the valve is opened when the suction signal is received.
An integrated sensor measures the vacuum. The exact vacuum level is shown on the display and can be read from the
IO-Link process data.
The air saving function is not available for the FMP-i version. The valve is controlled exclusively via signals.
3.2.1 Setting Down the Load
In blow-off mode, the ejector is deactivated and the valve is closed, and the inside of the gripper is supplied with
compressed air. This ensures that the vacuum drops quickly, thereby depositing the workpiece quickly.
During blow-off, [-FF] is shown on the display.
The gripper provides three blow off modes for selection:
•Externally controlled blow off
•Internally time-controlled blow off
•Externally time-controlled blow off
•Optional: external blow off
3.2.2 Description of Functions: Valve Technology SVK
NOTE
Tilting the area gripper with SVK technology
Limitations of the functionality
The valve technology SVK functions optimally when the gripper is used exclusively horizontally.
•Maximum permitted swivel angle relative to the horizontal: 60°.
•Maximum permitted acceleration in the vertical direction: 5 m/s².
•It is not possible to provide additional suction or pick up other products later.

3.3.2 Sliding block strips
The t-slots are used for flexible mechanical attachment of the gripper using the sliding blocks. Suitable attachment kits
are listed in the “Accessories” section. The t-slots on the side offer the option of connecting sensors and additional
components.
3.3.3 Insert Element
The insert element was developed to optimize the flow and must not be removed, particularly when using the SVK
valve technology.
3.3.4 Valve film
The valve film is available as an SW film or an SVK film, each of which is available in suction row types 3R and 5R. This
plastic film allows the gripper to be quickly converted from the SW technology to the SVK technology.
The SVK valve technology is used for applications with very fast cycle times (e.g. benchmark for depositing of
workpieces with active blow-off pulse: approx. 0.3 sec.) The suction properties are also optimized for rough and
textured surfaces.
3.3.5 Area Gripper with Sealing Plate
The sealing plate is made of technical foam. The grid is available in 3R LL-20x7 (workpieces that are 25 mm or wider)
and 5R LL-12x5 (workpieces that are 20 mm or wider). The sealing plate has asymmetric holes and is designed for fast
replacement. An optional sealing plate with filter screen mat is available. This reduces the penetration of dirt and
extends the maintenance intervals.
Note on properties of sealing plates:
The technical properties and appearance of sealing plates may vary due to production conditions. The user is
responsible for testing whether a sealing plate is suitable for a specific application. We would be happy to assist you in
placing your first order by performing grip tests at our premises if you provide us with your original workpieces.
As the sealing plate height is also subject to tolerances, it is recommended that you check the height setting of the
gripper every time that the foam is replaced (50% foam compression before the workpiece is picked up is optimal).
This ensures that the gripper functions optimally and that the service life of the foam is not reduced.
This flexing makes the sealing plate more permeable to air. When a high number of working cycles is reached, it may
be necessary to replace the foam, even if there is no visible indication of wear. The sealing plate must not be cleaned
with the compressed air gun, as this will damage it.
3.3.6 Area Gripper with Suction Cups
Suction cup connection strip with plug-in suction cups
The main application of the area gripper with suction cups is picking up parts that are not rigid, such as some
cardboard boxes or bags. The strips with the suction cups are screwed to the main body. The suction cups are
available in diameters of 20 and 40 mm with 2.5 folds. An optional integrated filter plate is also available. The suction
cups can be replaced individually without tools.
Suction cup connection strip for screw-in suction cups
Optional suction cups with 1/8" connection nipples can be used for special applications.

Product Description
16 / 96 EN · 30.30.01.02851 · 01 · 03/22
3.3.7 End cover
The end cover has 1/8" female threaded connections. These allow an additional vacuum gauge or a vacuum switch to
be connected and a compressed air pulse to be supplied for blow-off and separation.
(The compressed air supply for separation can only be attached on the side with the marking holes.)
3.4 Function Unit
Both gripper types (FMP-i for an external vacuum generator and FXP-i with integrated vacuum generator) feature a
functional unit that also includes the controller. On grippers of type FXP-i, the plug-in ejector is connected to the end
cover with the control unit; on grippers of type FMP-i, the vacuum valve is connected.
3.4.1 Ejector Assembly
The ejector assembly for grippers FXP-i comprises the control unit and the vacuum generator. The two integrated
control valves are used to divert the compressed air according to the electrical signals. If necessary, the complete
assembly can be removed for maintenance purposes or replaced if faulty.
In this case, the information on the separately attached nameplate is required. Please specify when ordering
replacement parts, making warranty claims or for any other inquiries. The type plate is permanently attached to the
assembly and must not be removed.

Compressed air connection
The compressed air is connected via a ¼" plug-in screw union for a compressed air hose with an outside diameter of
12 mm for FXP-i and 8 mm for FMP-i. Use a PU hose to connect the compressed air. We recommend using
compressed air supply lines with the max. possible internal diameter whenever possible. If a hose with an insufficient
internal diameter is used on the compressed air side, the ejector/valve will not receive enough compressed air to
operate at optimal capacity. For grippers FXP-i that are longer than 838 mm, a compressed air connection is provided
on both end covers because two vacuum generators are used here.
Compressed air connection for separation (optional)
The 1/8" connection (4) for the optional separation pulse is located in the end cover. When the product is delivered,
the end cover is closed with a plug.
The compressed air connection (4) for separation should only be connected on the side with the markings (6) of the
sliding block strip. The markings are on either end of the section. The amount of compressed air can be set to the
customer’s requirements using the valve screw.
The separation pulse is needed when two or more air-permeable sheets are picked up during suction. The briefly
applied compressed air pulse separates the second sheet from the first. The valve screw setting can vary according to
the properties of the workpieces.
The separation function can only be connected if there is a marking hole at the end of the section! If you
wish to retrofit this function, please contact Schmalz to obtain the conversion measures.
Electrical connection
The electrical connection is designed as a 6-pin M8 connector. It supplies the gripper with voltage and communicates
with the controller.
3.4.5 Silencer on Grippers FXP-i
NOTE
Closing the exhaust air outlet (1)
Increase in the internal pressure in the ejector
The exhaust air outlet on the silencer housing must not be closed. If the exhaust air outlet is closed, the
internal pressure in the ejector and in the valves will continue to rise until it exceeds the maximum
permitted operating pressure. This can result in damage to the ejector and/or injuries.
The silencer housing is lined with sound-dampening material and serves to reduce the exhaust noise. For cleaning,
the housing can be quickly unscrewed and the dampening material can be cleaned with compressed air.
