2 Safety information
2.1 General safety notes
DANGER
The product can not offer the expected protection if it is integrated incorrectly.
bPlan the integration of the product in accordance with the machine requirements
(project planning).
bImplement the integration of the product in accordance with the project planning.
DANGER
Death or severe injury due to electrical voltage and/or an unexpected startup of the
machine
bMake sure that the machine is (and remains) disconnected from the voltage
supply during mounting and electrical installation.
bMake sure that the dangerous state of the machine is and remains switched off.
DANGER
Improper work on the product
A modified product may not offer the expected protection if it is integrated incorrectly.
bApart from the procedures described in this document, do not repair, open, manip‐
ulate or otherwise modify the product.
2.2 Correct use
The deTec2 Core safety light curtain is an electro-sensitive protective device (ESPE) and
is suitable for the following applications:
•Hazardous point protection
•Access protection
•Hazardous area protection
The product may be used in safety functions.
The deTec2 Core safety light curtain must only be used within the limits of the prescri‐
bed and specified technical data and operating conditions at all times.
Any instance of improper use, incorrect modification, or manipulation of the deTec2
Core safety light curtain shall void any warranty provided by SICK AG; furthermore,
SICK AG shall not accept any responsibility or liability for any resulting damage and
consequential damage.
2.3 Inappropriate use
The safety light curtain works as an indirect protective measure and cannot provide
protection from parts thrown out nor from emitted radiation. Transparent objects are
not detected.
Among others, the deTec2 Core safety light curtain is not suitable for the following
applications:
•Outdoors
•Underwater
•In explosion-hazardous areas

•At altitudes over 3,000m above sea level
•In environments with increased levels of ionizing radiation
2.4 Requirements for the qualification of personnel
The safety light curtain must only be configured, installed, connected, commissioned
and serviced by qualified safety personnel.
Project planning
You need safety expertise to implement safety functions and select suitable products
for that purpose. You need expert knowledge of the applicable standards and regula‐
tions.
Mounting, electrical installation and commissioning
You need suitable expertise and experience. You must be able to assess if the machine
is operating safely.

3 Product description
3.1 Structure and function
Overview
The deTec2 Core safety light curtain is an electro-sensitive protective device (ESPE)
consisting of a sender and receiver.
A series of parallel infrared light beams forms a protective field between sender and
receiver that protects the hazardous area (hazardous point, access, and hazardous
area protection). When one or more beams are completely interrupted, the safety light
curtain reports the interruption in the light path to the secure output signal switching
devices (OSSDs) by a signal change. The machine or its control must safely analyze the
signals (for example using a safe control or safety relays) and stop the dangerous state.
Sender and receiver automatically synchronize themselves optically. An electrical con‐
nection between both components is not required.

Figure 1: Sender and receiver
Protective field height
The protective field height indicates the range within which the test rod belonging to the
safety light curtain is reliably detected.
Protective field width
The protective field width is the dimension of the light path between sender and
receiver. The maximum protective field width is limited by the scanning range.
Resolution
The resolution describes the size of the smallest object detected by the safety light
curtain in the protective field. The resolution corresponds to the diameter of the test rod
belonging to the safety light curtain.
The safety light curtain has a resolution of 14 mm. This resolution provides finger
protection.
The safety light curtain has a resolution of 30mm. This resolution provides hand
protection.
