Introduction and Warnings
MRP-30F is a pneumatic magnet meant for attaching ferromagnetic parts in lifting, work holding or
automation applications. The magnet’s state, attached or detached, is changed pneumatically.
MRP-30F pneumatic magnet doesn’t need compressed air to keep its state. Air pressure is needed
only to change the state from attached to detached or vice versa.
 Please read this manual carefully before deployment to ensure safe use of the device.
 This device includes a source of magnetic field. A fluctuating magnetic field is produced
during the use in the proximity of the device.
 This device produces a magnetic field that may interfere with medical devices such as
metallic implants or cardiac pacemakers. Do not use this device and keep out of close
proximity unless you have approval from the manufacturer of the medical device or from
your physician.
 Do not disassemble or replace the parts of the device. Only pneumatic connectors are user
changeable.
 The device must not be used for lifting or transporting people.
 The permitted holding force must not be exceeded.
 Always pay special attention to the factors that may decrease the holding force of the
magnet.
 Do not operate a damaged or malfunctioning device.
 The designer and manufacturer of the system, which this device will be integrated into,
should always ensure that the complete system meets the local and national safety
regulations.

Technical Specifications
Dimensions:
- Length: 80.0 mm
- Width 54.8 mm
- Height: 80.0 mm
- Weight: 1900 g
Capacity:
- Rated holding force: 880 N (S355 S ≥ 12 mm plate)
- Rated lifting capacity for plate with safety factor 3: 30 kg (S355 S ≥ 12 mm)
- Residual holding force flat: maximum 1200 g
- Residual holding force for other shapes:
MRP-30F’s magnetic structure (similar to standard lever magnets) makes residual grip-
ping capacity sensitive to material and geometry of the lifted part. In extreme case, a
part up to 4 kg may stay connected to the magnet. This may happen just after the mag-
net has been turned OFF. When this behavior is critical to the application, the actual
parts need to be pretested with the MRP-30F magnet.
Environmental conditions:
- Operating temperature: 0 °C … +50 °C
- Storage temperature: -20 °C … +50 °C
- Humidity 0 % … 90 %
- IP67 (The device is protected from dust and temporary immersion up to 1 m)
Requirements for compressed air:
- Recommended pressure: 6.0 bar
- Functional range: 5.0 … 8.0 bar
- Water separation
- Particle filter ≤ 5µm
Information related to medical implants
- Safety distance for a person with active implanted device is 50 cm of air or other non-mag-
netic material. The distance is measured from the magnet or magnetic material
attached to it.
o Maximum static magnetic field of MRP-30F is 200 mT on the gripping surface.
o Interference with active implanted devices, e.g. cardiac pacemakers – Action level for expo-
sure to static magnetic fields is 0,5 mT [Directive 2013/35/EC].

Holding Force
Holding force and rated lifting capacity of MRP-30F can only be applied when the forces are per-
pendicular to the magnet's gripping surface.
The following factors affect magnet’s holding force:
- Material properties
- Thickness of the load
- Distance between gripping surface and attached load (airgap)
Holding force and lifting capacity of MRP-30F pneumatic magnet are rated with steel EN S355.
Most other steel materials produce lower holding force. Also hardened steel produces lower hold-
ing force.
Material’s capacity to conduct magnetic field depends on its thickness. A thinner material has
weaker capacity compared to a thicker material. Increasing material thickness increases the mate-
rial’s capability to conduct magnetic field until the magnet’s specific maximum value is reached.
Any material that separates the magnet's gripping surface from the surface of the load reduces the
total magnetic holding force. Reduction can be caused by non-magnetic materials or by materials
with weak magnetic qualities, such as, zinc or paint or similar coating, rust, frost or air. The dis-
tance between the surfaces caused by materials above is commonly called as airgap.
Surfaces must be clean and the airgap zero to achieve rated holding force. The load surface must
also be flat and it must occupy the gripping surface of the device completely.

The holding forces specified in this document are valid for steel EN S355. Most other
magnetic materials result in lower holding force.
When lifting a piece from a stack, also the piece below the lifted piece can be attached
to the magnet.
The forces caused by acceleration must be considered. For example, sudden moves
cause stronger forces than slow and smooth moves. Sudden moves may drop the load.
Before magnet attachment, make sure that the magnet's gripping surface and the load
material surface are clean of foreign materials to minimize the airgap that reduces the hold-
ing force.
Due to residual magnetism, the magnet's lifting surface may contain small magnetic
particles or pieces which reduce the holding force.
The load material surface may bend, which produces an airgap and reduces the hold-
ing force. Especially thin materials may cause this effect.
Do not lift the load higher than necessary. Unnecessary elevation of the load during
lifting increases the risk of damage or injury.
Installing the Device
MRP-30F pneumatic magnet can be mounted either from side(s) or from top. Mounting is done us-
ing M6 screws (4 pcs.) according to Figure 2. The pneumatic connections are made with 4.0 mm
hose.

Figure 2. Mounting dimensions of MRP-30F.
When the MRP-30F magnet is turned ON, a magnetic field is generated between the steel plates
of the magnet.
The installation construction around the magnet must not short-circuit the magnetic field. The parts
of the installation that connect the MRP-30F steel plates together must be made of non-magnetic
material, e.g. aluminum or stainless steel.

Using the Ixtur MRP-30F Pneumatic Magnet
The front (logo side) and back steel plates of MRP-30F have a pneumatic connector. When the air
pressure in the back side pneumatic connection is 6.0 bars higher than in the front side connection,
the magnet is set ON (attach the metal). When the air pressure in the front side pneumatic connec-
tion is 6.0 bars higher than in the back side connection, the magnet is set OFF (detach the metal).
The same pressure in both air hose contacts keeps the magnet’s current state. Even if the pres-
sure is lost, the magnet keeps the current state. For more accurate air pressure information, look at
the Technical Specifications of this user’s manual.
The magnetic holding force of MRP-30F magnet weakens, if magnetic field is short circuited out-
side gripping surface. This may happen if the steel plates are connected to each other with un-
wanted magnetic material.
If there is a chance that the magnetic field is short circuited by external magnetic part (besides the
load) during the gripping of the load, the MRP-30F magnet’s steel plates should be shielded by
non-magnetic material from such direction(s).
Short circuiting the magnetic field between the steel plates of MRP-30F reduces the holding
force and may cause the lifted object to drop. The load must be the only magnetic material in con-
tact with both plates.
Maintenance and Inspections
MRP-30F pneumatic magnet is maintenance free.
If MRP-30F pneumatic magnet has been dropped or it has been exposed to severe impact, the
magnet must be inspected for any damages.
Do not use the device if you notice any damage or malfunction.
