Basic safety notes
Intended use
The product was designed to grip and to temporarily and securely
hold workpieces and objects.
The product is intended for installation in a machine/system. The
requirements of the applicable guidelines must be observed and
complied with.
The product may be used only in the context of its defined applica-
tion parameters (6, Page 12).
SCHUNK assumes that application in question was tested with the
calculation program for gripping modules (SSG).
The product is designed for industrial use.
To use this unit as intended, it is also essential to observe the
technical data and installation and operation notes in this manual
and to comply with the maintenance intervals.
Not intended use
Use which is not specified as an intended use is for instance when
the product is for example used as a pressing tool, stamping tool,
lifting tool, guide for tools, cutting tool, tensioning mean, boring
tool.
Environmental and operating conditions
•Make sure that the product and the top jaws are a sufficient
size for the application.
•Make sure that the environment is free from splash water and
vapors as well as from abrasion or processing dust. Exceptions
are products that are designed especially for contaminated en-
vironments.

NOTE
More information are contained in the relevant chapters.
Protective equipment
Provide protective equipment per EC Machinery Directive.
Demands on the top jaws
Arrange the top jaws such that when the product is depressurized
it can reach one of the end positions either open or closed and
therefore no residual energy can be released when changing the
top jaws.
Constructional changes, attachments, or modifications
Additional drill holes, threads, or attachments that are not offered
as accessories by SCHUNK may be attached only with permission
of SCHUNK.
Personnel qualification
The assembly, initial commissioning, maintenance, and repair of
the product may be performed only by trained specialist person-
nel. Every person called upon by the operator to work on the

Types that can be ordered (☞catalog):
The inductive proximity switches used are equipped with reverse
polarity protection and are short-circuit-proof.
Make sure that you handle the proximity switches properly:
•Do not pull on the cable.
•Do not allow the sensor to dangle from the cable.
•Do not overtighten the mounting screw or mounting clip.
•Please adhere to a permitted bend radius of the cable (☞ca-
taolg).
•Avoid contact of the proximity switches with hard objects and
with chemicals, in particular nitric acid, chromic acid and sul-
phuric acid.

Assembly
16 03.02|SGB 32 - 50 |en
The inductive proximity switches are electronic components,
which can react sensitively to high-frequency interference or elec-
tromagnetic fields.
•Check to make sure that the cable is fastened and installed cor-
rectly. Provide for sufficient clearance to sources of high-
frequency interference and their supply cables.
•Parallel switching of several sensor outputs of the same type
(npn, pnp) is permissible, but does not increase the permissible
load current.
•Note that the leakage current of the individual sensors (approx.
2 mA) is cumulative.
NOTICE
Max. indentation force (F) of the locking pins is 20 N.
