Renishaw, is adding to its extensive optical encoder range with the launch of the Vionic series, a new set of ultra-high accuracy, super-compact all-in-one digital incremental encoders. Designed for ...

Optical encoders have been used to measure position, speed, acceleration and motion direction for decades, but now they are finding new applications where high performance and miniaturization are ...

Direct-drive systems are firmly entrenched in the semiconductor and electronics-manufacturing industries, and are becoming increasingly common in the machine tool industry. Direct-drive systems offer ...

A high-accuracy 20-bit resolution quasi-absolute encoder with DSP-based signal processing is housed in a dc stepper motor assembly, as shown in Fig. 1. Able to operate in a temperature range between ...

Controlled servo drives function in many areas of automation technology, from robotics and handling systems to the drive technology of production machines and machine tools. The requirements of speed ...

It takes considerable time and effort to manufacture “perfect” surfaces. The mirrors on NASA’s James Webb Space Telescope, with a surface area of about 25 m 2 and finished to accuracies of 25 nm, took ...

Rotary encoders sense changes in the position of a rotating shaft, then generate signals that send speed, direction, and position information to a receiving device such as a counter, drive, or ...

For the first time ever high-resolution sine-to-digital converter iC-NQC provides the microelectronics industry with a BiSS C slave protocol that enables bidirectional data exchange at the same time ...

An absolute rotary encoder determines the angular position of a shaft on the basis of a static reference point. They are sensors that generate digital signals that correspond to the position in ...

Encoders, whether rotary or linear, absolute or incremental, typically use one of two measuring principles—optical or magnetic. While optical encoders were, in the past, the primary choice for high ...

Rotary encoders convert a shaft's angular position into an analog or digital code. They are characterized as either incremental or absolute devices: incremental encoders are capable of tracking motion ...
