Introduction and Warnings

MRP-20NK is a pneumatic magnet meant for gripping ferromagnetic parts in lifting, work holding or
automation applications. It is suitable for plates and round objects. The magnet’s state, attached or
detached, is changed pneumatically. MRP-20NK 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: 114.0 mm

- Weight: 2.4 kg

Capacity:

- Rated holding force: 590 N (S355 S ≥ 4 mm plate)

- Rated holding force: 380 N (S355 cylinder ø ≥ 14 mm)

- Rated lifting capacity for plate with safety factor 3: 20 kg (S355 S ≥ 4 mm)

- Rated lifting capacity for solid round object with safety factor 3: 13 kg (ø ≥ 14 mm)

- Residual holding capacity: 0.1 kg

The residual gripping capacity, i.e. the gripping capacity when the magnet is OFF,
varies based on the material and geometry of the gripped part. In extreme cases, parts
up to 0.1 kg may stay attached. The residual capacity is greatest as long as the part
continuously stays in contact with the magnet after the magnet has been turned from
ON to OFF. If the amount of residual capacity is critical to the application, pretesting
with the actual part is recommended.

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 non­magnetic material. The distance is measured from the magnet or magnetic material
attached to it.

o Maximum static magnetic field of MRP-20NK 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].
