GENERAL
• The data published in this manual are based on the most
recent information. They are published subject to changes
at a later date. For further info, please contact Goudsmit

• The "General Conditions for the Supply and Erection of
Mechanical, Electrical and Electronic Products (SE 01)",
published by Orgalime in Brussels in September 2001 apply
to this product.
• The guarantee on your Combi Gripper will be void if it is
opened, if basic changes are made to it without permission
or if the Combi Gripper is used injudiciously, wrongly or for
purposes other than for the gripping of products with the
help of magnetic and/or vacuum force.
SAFETY
• The magnet generates a strong magnetic field. Be aware
that ferromagnetic parts that enter the magnetic field can
be suddenly forcefully attracted.
• People with a pacemaker are not allowed to be present
within the magnetic field (radius of at least 0.5 m) of the
Combi Gripper.
• Credit cards, chip cards, screens, watches, etc. can be
damaged irreparably if they are present within the magnetic
field (radius of at least 0.5 m).
• The Combi Gripper has a safety protection and is not
allowed to be opened, not even to carry out repairs!
• The Combi Gripper is used for hoisting loads. Danger is
always present when transporting hoisted loads!
• Falling loads can cause danger to people passing below.
Adopt protective measures and ensure that there are
proper instructions and operating rules. Never pass below a
hoisted load.
• To the best of our knowledge, permanent magnetic
radiation does not endanger health.
The Combi Gripper offers many advantages:
• Double strength, therefore ferromagnetic products can be
handled with double safety.
• Also perforated products can be handled with the help of
the magnet system.
• Also non-ferromagnetic products such as aluminium and
stainless steel can be handled with the vacuum system.
• A Combi Gripper is available for any plate thickness to be
handled.
• It is possible to lift thin plates (temporarily) one by one by
means of only vacuum force.
• Antislip magnetic work surface due to wear resistant PUR-

Profile.
• With the application of a permanent magnet system, the
Combi Gripper needs no electricity.
Temperatures: Suited for ambient temperatures of -20 to
+40°C.
Noise: The noise pressure level of the Combi Gripper is less
than 70 dB.
Vibration: The vibration generated by the Combi Gripper is
negligible.
Air pressure: Maximum 6 bar (see over for recommended
connection pressures).
Hoisting strength: See Table 1. The hoisting strength for
different plate thicknesses is stated.

The given magnet strengths are for ideal circumstances.
Factors that may reduce these strengths are:
• Air fissure between plate and magnet (also an isolator such
as e.g. a paint layer can work like an air fissure).
• Contact surface: both plate and magnet must be as dry,
smooth, clean, and level as possible, without cracks, rust or
burrs or flash.
• Plate thickness: in the case of a thin plate, the magnet has
less hoisting strength.
• Perforation degree: in the case of a perforated plate the
hoisting strength is reduced.
• Bending: in the case of a plate bending there is a "peeling
effect", resulting in a great reduction of the magnet
strength.
• Temperature: a higher temperature reduces the hoisting
strength.
• Material for hoisting: see Table 2 for reference:
material
St 37 (0,1-0,3% C)
non-alloys (0.4-0.5%C)
alloys F-522
AISI 430 magnetic st. steel
cast iron
AISI 304 st. steel / nickel
Brass, aluminium, copper, etc.
Table 2: Relative magnet strengths with various materials
Also the given vacuum strengths can be (negatively)
influenced; in particular by the roughness and flatness of a
plate.
MAINTENANCE
Depending on using circumstances, vacuum pad and bottom
lid should have to be checked once a week, or at least once a
month on pollution and wear.
CONNECTIONS
By connecting two compressed air tubes (connections 'T' and
'B') the Combi Gripper can be switched on and off. Connection
'T' (Top) switches on the magnet force, connection 'B'
Combined
force [N]
(Bottom) switches it off. Also, via connection 'B' the vacuum

force is created.

The Combi Gripper itself operates bistably: the most recent

switching order is maintained.

If you have your own vacuum connection, the Combi Gripper
440
600
can be operated with only a 5/3-valve, if you do not have one

you can use the
Goudsmit vacuum blow
off valve (TPMV000004)
with integrated vacuum
venturi. On the reverse
side the pneumatic
diagrams of 3 possible
connections are given.
