2 On safety
This section concerns your own safety and the safety of the system operator.
bPlease read this section carefully before you begin working with the IN4000 Direct
series of inductive safety switches, or the machine protected by these safety
switches in conjunction with the corresponding protective devices.
National and international legal regulations apply to the use/installation of the IN4000
Direct series of safety switches as well as to their commissioning and recurring techni‐
cal inspections, in particular
•the Machinery Directive,
•the EMC Directive,
•the Work Equipment Directive,
•the safety regulations, and
•the accident prevention regulations and work safety regulations.
2.1 Qualified safety personnel
The safety switches must only be installed and commissioned by qualified safety per‐
sonnel. A person is considered qualified safety personnel if he/she
•has taken part in adequate technical training
and
•has been instructed by the machine operator in machine operation and the appli‐
cable safety guidelines
and
•can access these operating instructions.
2.2 Applications of the safety switches
The IN4000 Direct series of safety switches are inductive safety proximity switches that
are actuated by metal in a non-contact manner. The safe state is the de-energized state
(logical “0” of an OSSD).
The IN4000 Direct series of safety switches and the corresponding machine or system
controller can be used, for example, to protect movable physical guards in such a way
that:
•the dangerous state of the machine or system can only be switched on when the
protective devices are closed.
•a stop command is triggered if a protective device is opened while the machine is
running.
For the controller, this means that:
•switch-on commands that result in dangerous states may only be activated when
the protective devices are in the protective position,
and
•dangerous states must be ended before the protective devices are moved out of
the protective position.
Before using the safety switches, a risk assessment must be carried out on the
machine.
Intended use also includes compliance with the relevant requirements for installation
and operation.

Subject to change without notice
The safety switches must be subjected to periodic technical inspections (see "Periodic
technical inspections", page 20).
2.3 Intended use
The IN4000 Standard series of safety switches may only be used as described in
section “Applications of the safety switches”. The safety switches may only be installed
by qualified safety personnel and may only be used on the machine on which they
were installed and commissioned for the first time by qualified safety personnel in
accordance with these operating instructions.
The product may be used in safety functions.
The safety switch must only be used within the limits of the prescribed and specified
technical data and operating conditions at all times.
If used in any other way or if alterations are made to the devices – including in the
context of mounting and installation – any warranty claims directed to SICK AG will be
rendered void.
2.4 Reasonably foreseeable misuse
The safety switch is not suitable for the following applications, among others:
•In the vicinity of chemical and biological media (solid, liquid, gaseous)
•In environments with increased levels of ionizing radiation
2.5 General safety notes and protective measures
The safety switch performs a personal protection function. Improper installation or
manipulation can lead to serious personal injuries.
The safety switch complies with the following safety requirements:
•SIL3 according to IEC 61508,
•SILCL3 according to EN 62061,
•Performance Level e according to EN ISO 13849-1 (depending on application).
Change information
•For devices up to CW24 2018, the following applies:
PFHD 1.33 × 10–9/Category 4 (EN ISO 13849-1)
•For devices on or after CW25 2018, the following applies :
PFHD 1.0 × 10–8/Category 3 (EN ISO 13849-1)
bPlease check whether the device meets the safety requirements of your applica‐
tion.
Note regarding the classification of the device according to EN60947--5-2:
•The IN40-E0101K safety switch complies with the I1C40SP2M or I2C40SP2M
classification, depending on the installation method.
•The IN40-E0109K safety switch complies with the I2C40SP2M classification,
depending on the installation method.

WARNING
Safety switches must not be circumvented, rotated away, removed, or rendered ineffec‐
tive in any other way. Their contacts must not be bridged.
The inductive safety switches respond to metallic objects. Other metallic objects that
are not intended to trigger the safety function must not be placed on the sensing face
of the safety switches under any circumstances. Appropriate measures must therefore
be taken to prevent this.
Please observe the installation measures according to ENISO14119.
Damaged devices must be replaced.

3 Product description
3.1 IN4000 Direct Series safety switches
The safety switch has a cuboid housing with an alignable active sensor face. Its classi‐
fication according to EN60 947--5-2 depends on the mounting method (see table 4,
page 14).
3.2 Features and principle of operation
The IN4000 Direct series of safety switches are typically used for safe position detec‐
tion, as is the case, for example, when monitoring a movable protective device. The
sensor detects the presence of metal. In order to meet the requirements against easy
manipulation, the switching range of the sensor is monitored in time and space.
Its status can be read directly on the sensor or the protective device by means of
LEDs. Errors, such as a coil break, short-circuit or wire break are detected by the
self-monitoring function of the sensor.
The safety switch can be connected directly to a safe PLC or to a SICK safety controller,
e.g., Flexi Classic or Flexi Soft.

Distance
Figure 1: Schematic illustration of the zones
The output of the safety switch is only enabled in the event of actuation within the
enable zone. Outside the enable zone, i.e., also in the close range, the output remains
switched off.
After actuation in the close range, either the supply voltage must be interrupted or the
actuator must be brought into the assured switch-off distance for more than 2s before
it can be enabled again.
The enable zone depends on the type of safety switch and the material and shape of
the actuator. Using other actuators (material, shape) results in a different enable zone.
Typically, the following enable zones are achieved at an ambient temperature of 20°C
with non-flush installation of the safety switch using a standard plate according to
EN60 947-5-2 (IN40-E0101K: 45×45×1mm³, IN40-E0109K: 60×60×1mm³)
and with different materials:
