• You wear shoes that are suitable and approved for the discharge of electrostatic charges.
►Do not bring electronic assemblies into contact with plastics and parts of clothing that have plastic content.
►Store electronic assemblies on conductive underlays only.
►Do not install electronic assemblies in the vicinity of data back-up devices or monitors (monitor distance >
100 mm).
►Perform measurements on electronic assemblies only if:
• The measuring instrument is grounded (e.g. via a ground conductor).
• The measuring head is momentarily discharged before measuring with a oating measuring instrument.

5 Product description
CAUTION
Reduction of the gripping force can cause personal injury and material damage
When exible components are gripped, the gripping force of the product is reduced.
Reduced gripping force can lead to personal injury or material damage, because the components that are being
gripped can no longer be securely gripped and transported.
NOTICE
►Make sure that the setting of the gripping force and the selection of the gripper nger length are correct to
prevent incorrect bracing of the gripper jaws.
ÖAn incorrect conguration or selection can lead to malfunction
5.1 Possible applications

5.4 Use in applications
The criteria listed below justify the suitability of
the product for use in collaborative
applications:
• The product has been designed in
accordance with the specications of ISO/
TS 15066.
• The power of the motor in combination with
the transmission design and the pre-as-
sembled gripper jaws is not su󹱺cient to
generate a gripping force > 140 N upon
vulnerable areas of the body.
• The gripping forces generated when
gripping soft objects are signicantly
reduced, since the amount of dynamic force
is lowered. Compliance with the maximum
permitted gripping force has been veried
using a suitable measuring instrument.
• The product is engineered to be inherently
safe and is designed with rounded edges
and shapes that prevent crushing and
shearing points from being created.

6 Functional description
The gripper jaws of the product are arranged parallel to each other on two opposing guide rails and can be moved relative
to each other.
The force of the motor is transmitted by a worm drive. A pinion and a rack generate the movement of the gripper jaws and
synchronize these movements.
Despite its small installation space, the product is suited for gripping a wide range of form-t and frictional t parts.
You can optionally adjust the gripping force to the workpiece by using the control system via IO-Link.
Depending on the installation size, the product can be integrated and controlled via IO-Link or digital inputs and outputs in
existing control systems.

10.4 Safe shutoff for products with IO-Link
INFORMATION
For safe shutoff for IO-Link products, two contactors are switched in series with one auxiliary contact each. Here,
the auxiliary contacts monitor the status of the contactors. If one contactor does not switch, the second contactor
ensures safety. The malfunction can still be detected using the contacts.
The following gure shows the example of a circuit through which the IO-Link master cannot conduct the load current of the
product.

NOTICE
Without an externally fed voltage supply,the motor of the product cannot carry out an active movement and thus
cannot carry out a hazardous movement.
There is no galvanic separation between the two voltage supplies (signal and power). There is a low-voltage
connection via the ground (GND).
Because of the self-locking mechanism, the product remains in the last approached position, even if no voltage is
supplied.

10.5 Installing the energy supply
CAUTION
Non-compliance may result in material damage.
Incorrect pin assignment can lead to malfunction or destruction of the product.
►Be absolutely certain to ensure correct pin assignment.
NOTICE
The cables that are used by Zimmer GmbH feature a minimum bending radius of 10 x the outer diameter.
This bending radius must not be undershot!
►Freely suspended cables must be secured to prevent excessive motion loads or pinching.
►The contacts of the energy supply must be dry, clean and undamaged at all times.
ÖDamage to the contacts can result in malfunction of the product.
►Connect the power supply cable to the
control system of the product.
