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 […]
Absolute Encoders
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 […]
Networked rotary encoders from Advanced Micro Controls boast new features
Advanced Micro Controls Inc. has added new features to their NR60E2 series of networked absolute rotary encoders. The new features include a Profinet interface, E2 Technology, Hub Shaft (Blind Shaft) Option, and Stainless Steel units. These rotary sensors provide an overall measuring range of 16 bits (single-turn resolution) plus 14 bits (number of revolutions), for […]
World’s smallest multi-turn absolute kit encoders unveiled
Size matters, and in the world of industrial automation, providing exceptional performance in a highly compact package can be an enormous advantage. With this in mind, encoder manufacturer Posital has unveiled a fully functional prototype of their new miniature multi-turn kit encoder for integrated motor feedback. With a diameter of only 22 mm and a […]

In the world of industrial automation, providing exceptional performance in a highly compact package can be an enormous advantage. So encoder manufacturer POSITAL has unveiled a fully functional prototype of their new miniature multi-turn kit encoder for integrated motor feedback. With a diameter of only 22 mm and a height of 23 mm (0.87 in.) […]
IXARC absolute encoders with IO-Link interface from POSITAL
POSITAL has announced that its family of absolute IXARC rotary encoders has been expanded to include support for the popular IO-Link communications interface. IO-Link is a low-cost, easy-to-implement communications system designed to simplify connections between large-scale fieldbus or industrial Ethernet networks and sensor or actuator devices located on the factory floor. On one side of […]
POSITAL-FRABA multi-turn hollow shaft kit encoders — Rockwell Encompass Complementary Products
POSTIAL-FRABA’s new hollow-shaft kit encoders are now a complementary product in Rockwell Automation’s PartnerNetwork Encompass program. These new products mark a significant innovation for industrial motion control. Until now, almost all through or hollow-shaft encoders have been limited to a single-turn measurement range, largely because fully satisfactory multi-turn technology has been not been available. POSITAL […]
What happens when a multi-turn encoder reaches 4096 turns?
One of the first decisions when choosing a rotary encoder is whether it should provide incremental or absolute position feedback. That choice primarily depends on whether the encoder should be able to exactly detect its position upon startup. If so, then an absolute encoder is typically required. When considering an absolute encoder, the next decision […]
