Joral LLC now has a new method to impart total encapsulation in its J1 electronic components. Specially crafted to ensure total protection from extreme temperature fluctuation, intense machine vibration, and pressure wash down, the Joral J1 line-shafted rotary encoders perform rotary motion feedback for industry, ranging from directional drilling rigs to timber harvesters. The new […]
Joral introduces true non-contact rotary encoder with rectangular design
PE18 ProxEncoder non-contact rotary encoder product line receives a square housing with side sense capacity. Enhancing the original PE18 proximity style form factor, the new rectangular design allows for easy mounting on flat surfaces. Two USPTO patents enable the PE18-BX ProxEncoder to detect on-axis rotation with up to 0.5-in. (12mm) air gap between the application and […]
POSITAL expands rotary encoder offerings with new through-hollow incremental encoders
POSITAL has extended is portfolio of rotary encoders with a new family of through-hollow incremental encoders. These devices are designed to be installed with the machine shaft passing through the sensor. They can be used to monitor rotary motion in a wide variety of machinery, including servomotors, material handling equipment and printing presses, offering cost-effective, […]
True non-contact rotary encoder
Joral LLC introduces the PE18 ProxEncoder non-contact rotary encoder product line. Modeled in a threaded proximity switch housing, the 18mm 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. (12mm) air gap between the application and […]
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 […]
