The EtherCAT RFID module enables
HF and UHF read-write heads to run
at the same time, thus simplifying applications
with different bandwidths
and reducing the range of inventory
needed. The TBEC also supports the
HF continuous bus mode by which
up to 32 bus-capable HF read-write
heads can be connected to each of
the four RFID channels. Sensors, lights
or other actuators can be connected
to the eight universal DXP I/Os. All
terminals are implemented as five-pin
M12 male connectors, and the power
supply (L-coded) is implemented with
the future-proof M12 power technology.

Stainless-steel butterfly valves
help streamline material flow
This company's range of butterfly
valves (photo) are offered with a highly
polished 316 stainless-steel housing
and disc, which make the valve
suitable for many applications in the
food, chemical and pharmaceutical
industries. The inflatable seat design
of the butterfly valve provides an improved
seal by utilizing air pressure to
expand the seat against the disc, providing
more sealing area and an even
pressure distribution against the disc
every time it closes. The seat automatically
compensates for wear when
it inflates against the disc, extending
valve life considerably. Because
the valve's disc only makes casual
contact with the seat during opening
and closing, torque requirements
are substantially lower that those experienced
with other butterfly-valve
configurations. This ease of movement
also allows the disc to come to
a precise 90-deg position every time
it opens. Additionally, the smooth
profile of the disc eases material flow
and reduces buildup. These stainlesssteel
butterfly valves are available
in sizes ranging from 2 to 20 in. -
