AOPD (ACTIVE OPTOELECTRONIC PROTECTIVE DEVICE) WITH
ALUMINIUM HOUSING AND M12 CABLE CONNECTOR
During semi-automated heat staking of assemblies
manufacturers use light curtains to preserve operator safety
without compromising production throughput. The active
optoelectronic protective device (AOPD), mounted directly in
front of each bench-mounted heat-press, prevents the press-
head from descending if it detects any intrusion in the
working area, halting the operating cycle immediately.
CUSTOMER APPLICATION
Heat-staking is a popular process for fastening metal parts to
plastic moldings, and is commonly used by manufacturers
during the production of sub-assemblies. At each station, an
operator loads a molding and one or more metal parts into a
slide-mounted assembly fixture. Once the components are
correctly inserted, the operator pushes the slide into position
beneath the press-head, triggering the automated heat-
staking cycle.
The heated press-head, which may reach temperatures in
excess of 350oC (660oF), descends toward the pre-positioned
components. It applies heat and pressure to specific areas of
the molding, causing a controlled thermal deformation that
creates a permanent joint between the metal parts and the
molding. Following a pre-determined dwell period, the head
returns to the raised position, ending the cycle; the operator
withdraws the slide and removes the assembly from the
fixture.
Existing mechanical safety barriers are cumbersome and
inconvenient; throughput is constrained as a result of the time
taken to open and close the guards during each cycle. The
company requires an alternative safety guard that provides
effective hand protection while allowing unobstructed loading
and unloading. It must be simple, space-saving and operate
reliably in the production environment.
APPLICATION - LIGHT CURTAINS ENSURE SAFETY
DURING HEAT STAKING ASSEMBLY OPERATIONS
CUSTOMER SOLUTION
The company’s risk assessment confirms that Type 2 AOPDs
(active optoelectronic protective devices) would ensure
appropriate operator protection. Designed for applications
where the risk has been evaluated as moderate, Safetinex IEC
61496 Type 2 light curtains from Contrinex are rated to EN/ISO
13849-1 Category 2, Performance Level PL c and IEC 61508
Safety Integrity Level SIL 1, making them ideal for the
application.
The heat-staking press is housed in an open-fronted enclosure
with clear impact-resistant walls. The light curtain has an
operating range of up to 12 metres and a resolution of 30 mm,
ideal for hand protection; it safeguards the open front area of
the press, allowing easy access when required. The protected
height is 795mm, ensuring safe operation without impeding
the operator during loading and unloading.
Manufactured with rugged extruded aluminium housings and
IP65 + IP67 protection, these units are well-suited to the
production environment and will withstand shocks and
vibrations.
Industry-standard PNP normally-open configuration allows
connection to the customer’s control system via an integral 5-
pin M12 cable connector. These units have an integrated
alignment LED and permanent autocontrol – a feature not
usually found on Type 2 safety devices.
The new sensors take up much less space than the
mechanical guards they replaced, improving workplace
ergonomics. Loading and unloading is no longer impeded,
increasing productivity while actively safeguarding operators.
Safetinex Type 2 light curtains provide a reliable and cost-
effective solution.
HAND RESOLUTION (30MM) TYPE 2 & TYPE 4 SAFETY LIGHT CURTAINS PROVIDE COST-EFFECTIVE CHOICES
WHENEVER SAFETY REQUIREMENTS ARE MODERATE AND THE RISK ASSESSMENT ALLOW THEIR USE.

TYPE 2 & TYPE 4 SAFETY LIGHT CURTAINS - HAND RESOLUTION (30MM) - LOTS OF CHOOSE
If the risk assessment allows for their use, Type 2 Light Curtains are a cost-effective choice for which Contrinex offers parts from its
BASIC (42 x 48mm), or BASIC SLIM (26 x 26mm) ranges.
For Type 4 requirements, light curtains are offered in the BASIC (42 x 48mm) and EXTENDED SLIM (26 x 26mm) ranges..
The BASIC and BASIC SLIM range offers robust extruded housing (42 x 48mm, or 26 x 26mm respectively) , TÜV, CE and UL-
certification according to IEC 61496-1 and -2 and ISO 13849-1. They feature permanent autocontrol and low power consumption with
easy and low-cost installation provided by their use of an integral 5-pin M12 connector or pigtail.
The EXTENDED SLIM range are all Type 4 light curtains which are TÜV, CE and UL certified according to IEC 61496-1 and 2, IEC 61508-
1/2/3 and ISO 13849-1. Protective heights range from 170 to 1610 mm with integrated EDM*, restart interlock and beam coding. Since
EDM includes a relay monitoring function, users can also avoid the cost of wired relays.
The slim housing (26mm x 26mm) enables blind-zone free installation and connection is via an integral 5-pin or 8-pin M12 pigtail.
Bluetooth(R) wirless connectivity for configured and monitoring is offered using a free smartphone app – A world first!

LONG DETECTION RANGE
A high pressure/high temperature degreasing tank line is used
to clean machined metal parts for the automotive industry. To
protect operators from possible injury while degreasing is in
progress, Safetinex YBB-30 safety light curtains have been
installed and connected to the machine control system.
CUSTOMER APPLICATION
The manufacture of automotive parts by stamping or
machining involves liberal use of oily lubricants. However,
these processes leave finished parts heavily laden with oily
residues that must be eliminated prior to assembly. A
degreasing tank line provides the necessary cleaning.
Degreasing tanks contain caustic fluids at high pressure
and/or high temperature, which effectively remove all traces of
lubricant and protective coatings. However, some aspects of
this process are potentially hazardous to both employees and
the environment. The high temperature and pressure at which
cleaning takes place means that anyone accessing the tank
while the process is running risks injury from caustic spray and
harmful vapours.
The containment method chosen must take account of the
need for human interventions, while ensuring operator safety.
Liability costs must be minimized and loss of process fluids
reduced. Electromechanical interlocks were considered, but a
simpler and more operator friendly solution was sought.
APPLICATION - LIGHT CURTAINS PROTECT
OPERATORS FROM HOT CAUSTIC CHEMICALS
CUSTOMER SOLUTION
With their ease of installation and use, Safetinex YBB safety
light curtains were selected for this application. They meet
safety category 4 of EN ISO 13849-1 as well as type 4 of DIN EN
61496-1 and -2.
The safety light curtain comprises a sender and a receiver unit.
Infra-red beams generate a protective field between the two
units. LED displays on the sender and the receiver indicate
field status, operating mode, transmission channel, and
alignment quality. Reliability is guaranteed by a fail-safe
electronic design with permanent autocontrol.
Positioning a safety light curtain near the point of access to
the tank lids prevents the operator from opening them while
cleaning is in progress. The extent of the protective field also
ensures that no operator can access the hazardous area by
reaching over, under or around the light curtain. Any object
entering the protective field will not only disable the spray jets
and stop agitation, but will also cause the control system to
idle before allowing access.
