Incremental Encoders
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 […]
What kinds of encoder features boost ruggedness? Solid-state electronics, maybe?
Digital technology boosts the reliability of rotary-encoder designs. By Jeff Smoot, VP of Application Engineering & Motion Control, CUI Inc. Encoder applications are all around us, from BattleBots to the Mars Rover, large construction vehicles to semiconductor manufacturing equipment, and in numerous medical and military applications. In short, wherever there is motion, an encoder is […]

Baumer encoder line provides long-term operation, minimizes downtime
Baumer announces a line of optical incremental encoders designed to solve operational challenges in the ports industry. The HOG86 optical incremental encoder series is optimally designed for rugged environments and incorporates Baumer’s robust design that minimizes device damage due to vibration, shock, and shaft currents often experienced with other products. The encoders are failsafe in […]
Pull-Up Resistor Basics
To understand a pull-up resistor, it helps to first understand how encoder output is generated. Incremental encoders can provide several types of digital output, with the three primary types being open collector, push-pull, and line driver. Open collector output is considered sinking, while the line driver type is considered sourcing, and push-pull output is both […]
FAQ: How do magnetic encoders work?
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 resolution applications, improvements in magnetic encoder technology now allow them to achieve resolutions down to one micron, competing with optical technology in many applications. Magnetic technology […]
What are capacitive encoders and where are they suitable?
Two types of encoders dominate the general industrial market—optical and magnetic. But capacitive encoders, a relatively new introduction, offer resolution comparable to optical devices, with the ruggedness of magnetic encoders. Currently, there are only a handful of vendors for capacitive encoders, but their suitability for applications requiring high precision and durability make them a good […]
