Safety light curtains
optimised for vibration
Leuze MLC 500-V Series safety light curtains
have been optimised specifically for applica-
tions subject to strong vibrations, such as for
safe-guarding presses, punching machines
and similar large equipment.
These reliable safety light curtains have
unusually slim dimensions of only 29 mm by
35 mm, but clever engineering has ensured
slightly set back front screens, reinforced side
walls and metal end caps, all of which result
in a sturdy construction.
In addition, the new vibration-resistant
Leuze MLC 500-V models were designed to
provide extra protection for the high quality
electronics.
The safety light curtains are mounted on
specially developed BT-2SB10-S swivel mount
brackets that are largely able to compensate
for excess vibration.
This is an important feature with long light
curtains, typically longer than 900mm. Shorter
light curtains can be simply and conveniently
mounted on machinery such as presses using
adjustable vibration-damped BT-2R1-S swivel
brackets.
Form fitting mounting is possible due to
removable swivel mount cylinders and this
means that there is no dead space into which
unpermitted access would be possible. With
the extended functionality of these V-models,
the user has access to functions that can be
adjusted without a PC.
These include three scan modes and fixed
and floating blanking. This simplifies and
speeds up the in-feed of the work pieces and
contributes to more efficient production, since
there is no interruption to the manufacturing
process.

Connecting industrial safety controllers
Molex, LLC has introduced Brad HarshIO Ethernet modules to provide a reliable solu-
tion for connecting industrial safety controllers to sensors and actuators in harsh duty
environments. Machine mountable in an IP67 rated housing, Brad HarshIOmodules are
ideally suited for industrial applications where liquids, dust or vibrationmay be present,
and have been tested to withstand shock, high-vibration and high temperatures.The
Brad HarshIO modules are designed for safety applications, up SIL3 (Safety Integrity
Level 3), Cat4/Ple, where communication over EtherNet/IP is needed to exchange safety
and standard control data and diagnostics information over a single Ethernet network.
The compact modules offer 12 safe inputs and four safe outputs, supporting
connection of single and dual channel safety devices - ideal for automotive ap-
plications running robots in cells.The digital inputs and outputs can connect to
both standard and safety rated sensors and utilises test pulses for connected
standard outputs to perform diagnostics on panel lamps, buzzers and
standard actuators. An overmoulded on-board memory key, available
internally or M8, stores the configuration allowing module replace-
ment in a minute without any special tools or re-commissioning.
