RENCO Encoders

RENCO Rotary Encoders
RENCO’s product program currently includes the R35i and RCML15 rotary encoders without integral bearing. They use the optical scanning principle and offer the greatest possible functionality while featuring the smallest possible dimensions, thanks in large part to their simple and self-centering installation method with the patented slide-lock mechanism. This makes them particularly suitable for operation in electrical drive technology, robotics, medical technology, automation, and building services engineering.

HEIDENHAIN produces the RENCO rotary encoders, and also sells them worldwide. This means that RENCO rotary encoders benefit from HEIDENHAIN’s comprehensive know-how in the development and production of encoders. HEIDENHAIN develops and manufactures linear and angle encoders, rotary encoders, digital readouts and numerical controls for demanding positioning tasks. To date HEIDENHAIN has shipped nearly six million linear encoders, over 15 million rotary and angle encoders, approximately 500,000 digital readouts and 260,000 TNC controls.

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.
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.
The high resolution of up to 10 000 signals 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.

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. 

Facility engineering
Modern residential, administrative and industrial buildings are equipped with a large number of motor-controlled systems. They include for example elevators, ventilation 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.
