1. INTRODUCTION
1.1. CONTRINEX
Contrinex, a multinational company with headquarters in Switzerland,
is specialized in the development, production and worldwide sales of
position sensors, RFID and safety systems. Contrinex employs over
500 people, including 25 highly qualified R&D engineers, operates
production units in Switzerland, China, USA, Sri Lanka and Brazil, has
its own sales offices in all the major markets and is represented in over
60 countries. Contrinex applies stringent management and production
principles, which are reflected in its ISO 14001:2004 and ISO 9001:2008
certifications. Additionally, Contrinex is subject to regular client-based
audits. Identical quality controls and equipment as well as staff recruit-
ment and training policies are implemented at the different production
sites, thus guaranteeing consistent product quality.
1.2. SAFETINEX SAFETY SYSTEMS
The Safetinex product lines produced by Contrinex offer high quality
safeguarding solutions for both personnel and machinery. Our specialists
in sensor technology have developed high-performance electro-sensitive
protective equipment. Our range of safety products comprises highly
sensitive devices for finger and hand protection as well as access control,
featuring various lengths and connection options. Safetinex products have
been developed in compliance with the applicable international safety
standards and have obtained the required product certification for use in
the European Union, the United States of America and all other countries
where the applicable IEC standards have been adopted.
1.3. ACTIVE OPTOELECTRONIC PROTECTIVE
DEVICES (AOPD)
When looking to build a safety system around a danger zone, the first
consideration is whether or not optical protection is suitable at all. For
this to be the case, it must be possible for the machine control to be
electrically influenced by means of the AOPD’s semiconductor output.
Moreover, it must also be possible to instantly terminate or exit the
hazardous process in every operating phase. Further, there must be no
danger of injury due to heat, radiation or from materials or components
ejected by the machine. If such danger exists, then either the optical
system is not suitable, or the danger must be otherwise excluded by
applying additional safety measures.
The selection of a specific type of safeguard involves an evaluation of
the hazard, in order to determine the applicable category or required
performance level PLr.
The choice of an active optoelectronic protective device (AOPD), such
as a safety light curtain, depends on:
–The relevant safety standards to be applied
–The definition of the safeguarding function
