As part of its ambitious NEXTGEN initiative, encoder-maker POSITAL has introduced a major update to its portfolio of IXARC magnetic encoders. While incremental encoders based on the new technology platform have been available for several months, the company is now rolling out a new generation of single and multiturn absolute encoders. These new encoders come […]
Absolute Encoders
Absolute encoders — facts and misconceptions
A little knowledge goes a long way — knowing and understanding the advantages and limits of encoders and limit switches can ensure the best possible motion system design. Ray Marquiss Senior Application Engineer for Automation Valin Corporation There are two parts of motion control systems often overlooked or misunderstood; encoders for either the motor rotation […]
Celera Motion debuts inductive encoder for automation in extreme conditions
Celera Motion, a business unit of Novanta Inc., has introduced the Field Calibration IncOder, a new absolute inductive encoder that achieves next-level accuracy angle measurement in motion control applications and position feedback in robotics in the most demanding environments. The Field Calibration IncOder is designed for applications that need precise angle measurements but in conditions […]
Absolute rotary encoders make omnidirectional motion a VR reality
Encoders are critical motion control components that provide feedback on a system’s position and speed. They are used in almost every industry — such as aerospace, robotics, packaging, and textiles — and are building traction in virtual reality (VR) treadmills. VR treadmills let users physically move in real-life space while navigating virtual environments. But unlike […]
Compact 36-mm absolute rotary encoders with analog interface
The new AV3650M and AH3650M absolute rotary encoders from SIKO combine precise and reliable position measurement in an extremely compact housing. The absolute position values are transmitted via several integrated analog interfaces, such as 0 to 10 V, 0 to 5 V and 4 to 20 mA. These encoders use the magnetic measuring principal, with […]
Shaft absolute encoder designed for harsh environments
The new Model A58SB absolute bus encoder from Encoder Products Company (EPC) is designed for harsh factory and plant floor environments. Heavy duty, rugged and reliable, this shaft absolute encoder is available in both single and multi-turn resolution. As an absolute encoder, it’s especially suited to applications where an encoder needs to retain position information […]
Absolute encoder interfaces: Differences between SSI, BiSS, Hiperface, and EnDat
Absolute encoders can communicate with controllers through parallel or serial wiring, over a fieldbus, or via an Ethernet-based protocol such as EtherCAT. Of these options, serial communication is a simpler solution than parallel wiring (which requires a twisted pair of wires for each bit of output) and is well-suited for applications that aren’t complex enough […]
Multiturn absolute encoders with line driver feature integrated referencing
In combination with brushless dc servomotors, the new magnetic AEMT-12/16 L absolute encoder from FAULHABER delivers absolute angle information with a preset multi-turn resolution of 16 bits (65,536 revolutions) and a single-turn resolution of 12 bits (4,096 steps) for commutation, speed control and motion control. This position data can be queried by an SSI Interface […]
Feedback on stepper motors for better positioning and holding (and less ringing)
Feedback-equipped stepper motors are not a complete substitute for servomotors, but they can provide a reliable alternative for many real-world applications. These motion-design solutions improve machine performance without breaking the bank. By Jim Stevens • Product Specialist | POSITAL Inc. Stepper motors are a top choice for many motion and position control applications. They’re available […]
Diverse-redundant absolute encoders for safety-critical applications from POSITAL
Sensor manufacturer POSITAL has introduced an inexpensive and flexible alternative for safety-critical motion control systems. Supplementing its existing range of formally certified SIL safety encoders, the new ‘diverse-redundant absolute encoders’, based on non-certified standard components, are a suitable choice for many installations where functional safety is required. When combined with functional safety PLCs, these devices […]
