FlexSense: Programmable Incremental Optical Encoder Sensor from TT Electronics

FlexSense: Programmable Incremental Optical Encoder Sensor from TT Electronics

TT Electronics, a global supplier of electronic components and solutions for performance-critical applications, has announced the launch of the FlexSense™ product line. FlexSense™ features revolutionary technology to optimize optical encoder applications in industrial and medical applications. The One-size-fits-many advanced optical array integrates several subsystems on one SOC, shrinking solution footprint, shortening time to market and cutting manufacturing costs. The FlexSense™ encoder sensor unit significantly simplifies optical encoder solutions.

“Low-cost control electronics are trending up. At the same time, demand for customized high-end optical encoder sensors is also growing. We saw an opportunity to address both developments in tandem,” said Walter Brooks, Global Product Manager – Optoelectronics, TT Electronics. “FlexSenseTM is the result: a flexible solution that can be configured quickly to meet optical encoder design requirements including higher resolution, faster response, a smaller footprint, and greater intelligence. With FlexSenseTM, TT customers can accelerate time-to-market, reduce solution complexity, and increase manufacturing throughput – now and in the future.”

The FlexSense™ series consists of the FS210 transmissive incremental encoder and the FS310 reflexive incremental encoder. The FlexsenseTM sensor integrates several key features including auto-alignment capability, a closed-loop LED driver, on-chip diagnostics, and a state-of-the-art 8x interpolator. In addition, the fully programmable array, system on chip (SOC) provides a versatile solution that can adapt to a multiple range of code-disk diameters and pulses per revolution as well as several LEDs available in the market, including TT’s OP207CL encoder LED. If the encoder code-disk is later altered, FlexSenseTM can be reprogrammed to meet changing requirements extending the sensor’s value-add to suit future designs and negating the cost of purchasing a different sensor.
