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
application parameters (6, Page 13).
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.
•Observe Maintenance and lubrication intervals (9.2,

Ferromagnetic material changes the switching positions of the
sensor. For example: Adapter plate made of ordinary steel.
At ferromagnetic adapter plates:
•The module must firstly be mounted on the adapter plate
•Then, the positions of the magnetic switch have to be set

Inductive proximity switch IN 80
Fig. 7 Connection example for IN 80
1 brown 2 black 3 blue
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. (☞
catalog)
•Avoid contact of the proximity switches with hard objects and
with chemicals, in particular nitric acid, chromic acid and
sulphuric acid.
The inductive proximity switches are electronic components,
which can react sensitively to high-frequency interference or
electromagnetic fields.
•Check to make sure that the cable is fastened and installed
correctly. 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 (ca. 2 mA)
is cumulative.
