Pepperl + Fuchs incremental rotary encoder series ENI58IL- Blu-ray technology

The ENI58IL incremental rotary encoder series launched by Pepperl+Fuchs this time introduced the Blu-ray code disc scanning technology ("BlueBeam" Technology) for the first time in the industry. Standard industrial rotary encoder products based on this technology can still achieve unparalleled high-precision performance when the working speed is as high as 12000RPM. These are all due to the blue LED transmitter and corresponding receiving optocoupler components, combined with high-performance sensor chips, to achieve efficient use of light.

New standard for signal quality of incremental rotary encoder

"Compared with the long-wave infrared light used in traditional rotary encoders, the blue light emitted by blue LEDs has a shorter wavelength, and can achieve clearer fringe images under the same code disc grating line width," Pepperl+Fuchs Global Stefan Horvatic, product manager, explained. Based on the innovation of this functional principle, the high reference signal quality expected by users is achieved. "Blu-ray code disc scanning technology makes the phase difference and pulse width fluctuation amplitude of the A and B channel output signals far less than 10%" Horvatic made a supplementary explanation. The achievable signal quality is more than twice that of the incremental rotary encoder of traditional infrared light technology. At the same time, because high-frequency sampling is not susceptible to interference, the Blu-ray technology encoder can still maintain signal stability in the case of strong mechanical shock and vibration.

Another technical advantage of the ENI58IL encoder is that it additionally uses a code disc calibration assembly process that exceeds standard manufacturing; in its production process, in order to ensure the precise insertion of the code disc, it must be calibrated under a microscope and other parameters. This process not only improves the absolute accuracy of product application, but also prevents the non-negligible performance loss caused by subtle deviations to customers.

Incremental rotary encoder with bearing lock design

ENI58IL series encoders, in addition to the introduction of blue light technology to achieve high-precision measurement, also made great efforts in reliability and durability: bearing lock design, protect ball bearings, can withstand greater axial load; special EMC protection circuit, Avoid encoder damage caused by strong electromagnetic interference. "At present, most of the rotary encoders sold in the world generally only meet the minimum requirements of the CE standard. Our test standards are four times better than the conventional standard levels, ensuring that the products can operate accurately and reliably under severe and challenging application conditions. "Mr. Horvatic said.

Multiple performance advantages, all in one

Based on the single-chip modular production process, the ENI58IL incremental rotary encoder perfectly integrates a very wide range of characteristics and advantages; its shaft type (solid shaft, hollow shaft, semi-hollow shaft), flange (clamping flange, servo Flange, square flange), electrical connection (radial, axial cable or M23/M12 connector) have a variety of styles to choose from. "The emergence of ENI58IL, a precision-designed industrial standard encoder series, has replaced the traditional special encoder equipment to meet special applications," Mr. Horvatic emphasized.
