2Fundamental Safety Instructions
2.1Intended Use
The magnetic gripper is used for handling ferromagnetic workpieces, such as perforated plates, complex
laser-cut workpieces, plates with drill holes and apertures.
The operator is required to document the static strength and holding force and to adhere to safety fac-
tors.
For system designs, a safety factor of S=3 should be applied.
The load to be lifted must be sufficiently rigid so that it is not damaged during gripping and handling.
The magnetic gripper is built in accordance with the latest standards of technology and is shipped in safe
condition. However, hazards can arise during use. Observe the warnings in these operating instructions.
The maximum lift capacity must not be exceeded (> See ch. Technical Data).
Do not operate the device in environments where there is a risk of explosion.
Do not operate the product in aggressive environments (e.g. ambient air containing solvent fumes).
2.2Non-Intended Use
Schmalz accepts no liability for damage caused by the use of the gripper SGM-SV for purposes other than
those described under Intended Use. Use of the gripper SGM-SV for loads that are not specified in the or-
der confirmation or that have different physical properties than those specified in the order confirmation
shall be considered non-intended use. In particular, the following are considered non-intended use:
• Use as a climbing aid
• Storing loads when active
• Removing building components or fixtures.
2.3Personnel Qualifications
Unqualified personnel cannot recognize dangers and are therefore exposed to higher risks!
The operating company must ensure the following points:
• The personnel must be commissioned for the activities described in these in-
structions.
• The staff must be at least 18 years of age and physically and mentally capa-
ble.
• The product must be operated only by persons who have undergone appro-
priate training.
• Personnel must receive regular safety briefings (frequency as per country-
specific regulations).
The following target groups are addressed in these instructions:
• Mechanical and electrical specialists who are responsible for installing, trou-
bleshooting and maintaining the product.
The operator of the system must comply with country-specific regulations regarding the age, ability and
training of the personnel.
Applicable for Germany:
A qualified employee is defined as an employee who has received technical training and has the knowl-
edge and experience – including knowledge of applicable regulations – necessary to enable him or her to
recognize possible dangers and implement the appropriate safety measures while performing tasks. Qual-
ified employees must observe the relevant industry-specific rules and regulations.

3Product Description
3.1Description of the Function
The magnetic gripper powered by compressed air lifts ferromagnetic workpieces using a magnetic force.
It is used for handling sheet metal and perforated plates, complex laser-cut workpieces, sheet metal with
drill holes and apertures, curved sheet metal and pipes.
To control the magnet, the system alternately supplies the two gripper connections with compressed air
while venting the non-actuated connection.
By applying compressed air, the permanent magnet is moved toward the gripping surface (gripping the
workpiece) or away from the gripping surface (releasing the workpiece).
The compressed air must be applied for at least one second to ensure reliable switching.
Gripping the workpiece

Depositing the workpiece

The bistable mode of operation allows safe gripping even during a power failure.

1 All holding forces are static and unsecured when gripper active surfaces are fully covered on steel plate
S235 at +20°C.
2 2mm sheet steel, with friction ring
3 Can be used for workpiece temperatures up to 350°C (depending on process conditions). The influence
of temperature can reduce holding forces by up to 30%.
4 Values using the optional friction ring
As the operating temperature increases, the holding force of the grippers decreases. We rec-
ommend performing tests before continuous operation.
The specified values apply to clean, smooth surfaces for low-carbon steel sheets. Dirty, rough,
and highly alloyed steel sheets reduce the holding force.
For maximum holding forces, the component to be handled must completely cover the grip-
ping surface.
Due to the design of the gripper, it is not possible to centrally grip parts that are smaller than
the gripping surface.

6.4Optional: Sensor for Monitoring the Piston Position of the Gripper
Magnetic grippers from series SGM-HT-HP are not intended for sensor operation due to their
application in the high temperature range.
Observe document 30.30.01.01624 Operating Instructions for Proximity Switch (Optional: Accessories) for
Magnetic Grippers.
After installation, always teach the sensor with the workpiece/part to be gripped (> See ch. 6.4.3 Mount-
ing the Sensor,p. 18).
6.4.1Preventing Sensor Malfunctions
The sensor may be installed in any position.
To ensure that the gripper functions properly and to prevent faults in the sensor function, observe the
following installation instructions:
•Use mounting elements or similar made of non-magnetizable material (alu-
minum, plastic, etc.)
• Check on a regular basis that the sensor is securely installed in the slot – in
particular when it is used in fast handling processes or ones that are ex-
posed to vibration.
• Strong magnetic fields can impair the functionality of the sensor. As a re-
sult, the suitability of the sensor for use, for example in close proximity to
welding plants, must be checked separately in each individual case.
• Keep magnetizable objects away from the sensor or place them at a suffi-
cient distance. Observe the minimum distances specified below.
• The sensor, sensor slot, and gripper(s) must be regularly inspected and any
ferromagnetic pollutants (such as iron shavings) removed.

Commissioning the sensor for first-time installation or resetting if necessary
1. Place sensor centrally in the T-slot.
2. Push the sensor to the stop of the T-slot,
or in the case of variants with open T-slot, fix
the sensor flush with the lower end of the slot
(towards the gripping surface).
4Fix the sensor with a screwdriver (torque: 0.2
+/- 0.05Nm).
4Connect plug M12x1 and apply operating voltage.
Teaching in the switching points
üUse the supplied teach-in tool or a plastic pin for the teach-in process; do not use magnetic tools
(screwdriver, steel hexagonal socket wrench, etc.).
üThe gripping apparatus/gripper tool is in the workpiece pick-up position.
1. Check sensor position: At the end of the T-slot
or flush with the slot end.
With the sheet clamped, set/actuate the piston
position for the first switching point (front pis-
ton in operating position).
