The company's new BIC M30
inductive couplers for non-contact
power transmission are particularly
suitable for production lines where
flexibility is required for non-contact
power transmission, fast data
transfer and condition monitoring.
They can transmit up to 1.5 amps
of continuous output, transmitting
the energy without contact. The
IO-Link interface of the inductive
couplers enables a frictionless,
transparent and fast exchange of

data between the IO-Link device and the IO-Link network module.
" A unique feature is the second IO-Link channel, which can
be used for process and diagnostic data and thus for condition
monitoring, " explains Herczeg.
" The encoders monitor rotary axes that control the precise
positioning of workpieces and the movement of machines and
systems, " explains Josef Albano, product manager. Rotary
encoders convert mechanical movements into digital electrical
signals. Depending on the application, they have different measuring
principles. If a high resolution is required, optical encoders
that measure incrementally are usually used. " With incremental
displacement measurement, each movement is measured by
the positive or negative increase in the distance traveled, " says
Albano. The incremental encoders measure angles with the
highest resolution. Among other things, encoders are available
especially for applications with a high shaft load, suitable up to
500 Newton.
The absolute encoders ensure high-precision positioning of
critical machine parts. " With absolute travel measurement, the
position is specified as an absolute value. This means that the
machine is ready for operation immediately after restarting and
does not require a reference run, " explains Albano. The absolute
encoders are particularly reliable; their data cannot be lost even
in the event of a power failure. Rotary encoders are used everywhere:
in automation technology, machine tools or food processing,
The new variants complement Balluff's extensive automation
portfolio.
Currently celebrating its founding 100 years ago, Balluff is based
in Neuhausen, Germany near Stuttgart. It operates 8 production
sites and 38 subsidiaries worldwide, employing about 3,600
people.

Magnetic encoders are typically the choice for harsh environmental
conditions as demonstrated by Balluff's new incremental
and absolute encoders designed for difficult environments and
high shaft loads for precisely measuring lengths, positions,
speeds, rotational movements and angles. In industrial applications,
process cycles are precisely timed, making essential the
control of rotational and conveyor speeds as well as the exact
positioning of workpieces.
