ENERGY + ENVIROFICIENCY
SMC, provider of pneumatics, redesigns its
air preparation modular units, the AC series,
thus ensuring its number one spot in the
marketplace.
The AC series design review is part of
SMC’s ongoing investment in research and
development to refine and improve the per-
formance and functionality of its products,
as well as developing new innovations to
drive enhanced handling and space sav-
ings and deliver competitive advantages
for customers. In this regard, the AC series
brings a double layer structure bowl guard
for better visibility and extended working
life, while also bringing reduced time and
space for maintenance. Much more space
saving is achieved due to the compactness
of the modular units and the integrated and
selectable pressure gauges and switches.
Moreover, the introduction of an in-bowl
assembled element construction, together
with a new bracket system that allows for
initial tightening by hand, allows for easier
control and quick in-hand maintenance and
replacement of elements. Ideal for automo-
tive, facility and machine manufacturing,
these highly flexible FRL units also feature
a simple to use bowl lock button and inter-
changeable, modular mounting.
Quick facts:
Better visibility and environmental resistance
Easy replacement of the element
The element and the bowl are in one piece
Replacement can be done in hand
Reduced required maintenance space: Max
46% reduction
Regulator: Set pressure 0,05 to 0,85 MPa,
0,02 to 0,2 MPa
Selection of pressure gauges
Square embedded type pressure gauge,
Round type pressure gauge,
Digital pressure switch

Belt drift switch for field applications
The new belt drift switch from ifm electronic is designed for heavy duty application and
used for drift monitoring of conveyor belt installations.The belt drift switches are used
to protect the installations from damage or destruction in the event of belt drift and are
positioned in pairs on both sides of the conveyor belt.The ball bearing stainless steel
actuating roller is resistant to wear and is used for belt speeds up to approximately
5 m/s.The device features a robust aluminium housing and
is equipped with two force-actuated changeover contacts
with a snap-action function with two adjustable switching
points. Inadmissible belt drift occurs when the belt edge
approaches the end of the supporting rollers through lateral
movement and surpasses it.Then the actuator (roller lever)
is operated and displaced. In case of displacement of the
actuator, the cam operating switches are activated. The
switching angle can be set via an adjustable camshaft. In
this way, a pre-warning can be implemented in addition to
the safety shutdown. As soon as the belt moves correctly,
the roller lever will automatically return to its home position.
