RENCO R35i and RCML15 Rotary Encoders
The
RENCO R35i
is an incremental rotary
encoder without integral bearing and with
optical scanning. Its special properties are
its
compact design
with 35 mm outside
diameter and only 14 mm height as well as
its
easy, self-centering mounting
thanks
to a patented slide lock. With its OPTO-ASIC
technology, the RENCO R35i offers
the
greatest possible functionality with the
smallest possible dimensions.
The
RCML15 rotary encoder
with a height
of only
8.9 mm
offers an alternative to the
R35i with a very low mounting profile.
Both encoders are available with output
signals for controlling motors with block
commutation.

Areas of application
The RENCO R35i is an incremental rotary
encoder without integral bearing and with
optical scanning. Its special properties are
its
compact design
with 35 mm outside
diameter and only 14 mm height as well as
its
easy, self-centering mounting
thanks
to a patented slide lock. With its OPTO-ASIC
technology, the RENCO R35i offers the
greatest possible functionality with the
smallest possible dimensions—ideal
preconditions for their use in the following
areas of application:
Servo drive technology
Thanks to its position acquisition with the
high resolution of up to 10 000 signals per
revolution (40 000 measuring steps after
four-fold evaluation) and the wide working
temperature range of –30 °C to +115 °C,
the RENCO R35i
is ideally suited as
feedback system for stepper motors in
the Closed Loop mode.
In addition, the
RENCO R35i provides three commutation
signals U, V, and W, in order to power in the
proper direction the rotor windings of
BLDC motors
(brushless DC motors) with
up to four pole pairs.
Robotics
Robotics is a strongly expanding sector of
industry. Thanks to new developments under
the rubric of “soft robotics, new areas of
”
application are opening up that extend far
beyond the classical industrial robots for
automation technology. In the future, an
increasing number of sensitive (i.e. soft),
service robots in immediate interaction with
humans will serve to assist in facilitating
manual processes in production.
Professional service robots are also
increasingly assuming jobs such as,
• cleaning facades or solar panels,
• inspecting pipelines,
• fully automatic harvesting aids in
agriculture,
• automatically controlled conveyor or
loading vehicles in logistics.
Thanks to its compact design and
outstanding performance data,
the
RENCO R35i is the ideal solution for all of
these applications. Moreover, it features
low energy consumption during
operation
for mobile, battery-powered
applications.
Medical technology
Thanks to various features and properties,
the RENCO R35i is very well suited for
demanding applications in the area of
medical technology. Its material mix is
RoHS conformant
and therefore contains
no hazardous materials as per EC Directive
2011/65/EU. In addition, its high reliability
and
noise-proof data transfer
with line
drivers as per EIA standard RS 422 play an
important role for high patient safety with
physiotherapeutic equipment and high
analysis quality and reproducibility in lab
applications. The high resolution of up to
10 000 signal periods per revolution fulfills
the requirement for
smooth, jerk-free and
precise control—which
is important both
for physiotherapeutic devices for patient
comfort as well as in liquid handling
applications in a lab. Typical areas of
application include physiotherapeutic devices
such as movement exercisers and lab
automation with centrifuges and pipetting
systems for liquid handling.

Automation
Automation applications such as in semi-
conductor manufacturing or in the food and
textile industries are interesting applications
for the RENCO R35i. Its strength is the
accurate positioning control
of machines
and systems with
high dynamics
at very
high signal resolution. Die bonders for
chip-on-board manufacturing, automatic
coiling machines for the textile industry,
palleting systems or automatic coin counters
are example applications. The high dynamics
of the RENCO R35i result from its short
signal processing times and the
high
resolution for precise positioning
from
its integrated interpolation. The compact
design of the R35i resulting from its ASIC
technology plays an important role in
factory automation, as well.
Facility engineering
Modern residential, administrative and
industrial buildings are equipped with a
large number of motor-controlled systems.
They include for example elevators, ventila-
tion systems or automatic doors and gates.
Thanks to its compact dimensions, here
the RENCO R35i is also excellently suited
for controlling elevator doors or rotational
speed in ventilation systems.
The providers of facilities technology place
great value on
reliability and failure safety.
These properties guarantee comprehensive
certification as per ISO quality standards.
The serial interface according to EIA
standard RS 422 ensures safe and reliable
data transfer. It offers
high noise immunity
through its differential, symmetric signal
transmission.
A
particularly flat-profile and light
alternative
to the R35i available in the
RENCO product line is the
RCML15
rotary
encoder. It can be used for the same
application areas, but thanks to its low
profile with a height of only 8.9 mm, it can
be used especially in applications with
critical installation conditions and
limited space.
In addition to its very flat
design, the RENCO RCML15 offers the
performance potential of a modern rotary
encoder. This includes a resolution of up to
5000 signals per revolution, commutation
signals U, V, W and an operating tem-
perature range of –30 °C to +100 °C. The
RCML15 also features a patented slide lock
mechanism for simple, self-centering
mounting.
