Joral debuts non-contact rotary encoder for harsh environments
Joral LLC introduces the PE18 ProxEncoder non-contact rotary encoder product line. Modeled in a threaded proximity switch housing, the 18-mm true non-contact encoder is designed to capture rotary motion where conventional sensors fail. Two USPTO patents enable the PE18 ProxEncoder to detect on-axis rotation with up to 0.5-in. (12 mm) air gap between the application […]
What is modulo positioning?
In motion control, there are typically two types of positioning that can be used for a linear or rotary axis: relative, in which each position is based on a previous position, regardless of the actual position of the axis; or absolute, in which each position is referenced to a home, or zero, point. Axes that […]
Bearing-free SIKO encoder: Redundant non-contact angle and distance measurement for mobile machines
In the field of mobile commercial vehicles, safety requirements are increasing, especially within the EU. This presents not only suppliers, but also manufacturers of vehicles, with new challenges. To make it as easy as possible for manufacturers to adapt to new requirements, the Buchenbach based firm SIKO GmbH has developed the MSK320R bearing-free rotary encoder. […]
FAQ: How do digital encoders simplify setup and zeroing?
In a recent Design World video, my esteemed colleague Miles Budimir and I got to assemble and zero an AMT31 commutation encoder from CUI Inc. As we’ve covered in other editorial, capacitive technology can outperform optical technology. Used for years in digital calipers and to measure rotational movement, capacitive technology in encoders replaces optical disks with a printed circuit-board rotor […]
What is TTL output for incremental encoders?
Updated August 2018 || Rotary encoders are used to track the angular position of a shaft, providing either incremental or absolute position information. Incremental rotary encoders work by generating pulses as the shaft rotates. By counting the number of pulses, the position of the shaft relative to its starting position can be determined. Rotary encoders […]
Hengstler adds to its series of ATEX-rated absolute rotary encoders
Hengstler’s new ACURO AX73 optical encoders offer attributes such as ease of installation, high precision and compact dimensions. The AX73 completes the company’s comprehensive family of ATEX-rated absolute rotary encoders, both optical and magnetic. The new AX73 and AX65 offer a special mounting system, while also available are the AX70 and AX71 absolute encoders, as […]
