Rotary encoders come in two basic varieties: absolute encoders report the actual position of the shaft at a specific time, while incremental encoders indicate relative changes in the shaft’s position.

This unique encoder technology combines the opto-mechanical simplicity of an incremental encoder with the system reliability and interfacing ease of an absolute encoder.

Following the recent announcement of a range of programmable incremental encoders from Sick, another German encoder manufacturer, Megatron, has come up with a programmable absolute magnetic encoder.

Pseudo-absolute encoders, also known as incremental encoders with index, are basically incremental encoders with a third channel added, i.e., the index. “This gives them the ability to act like ...

Heavy-duty IXARC encoders are offered in absolute and incremental versions, both based on POSITAL’s well-proven optical measurement technology. Absolute versions feature 13-bit resolution, with a ...

At their most basic level, encoders transform mechanical rotary motion into a sequence of electrical pulses that are monitored for display or control functions using a counter, display, PC, PLC, ...

LIKA offers new robust absolute encoder as single- or multiturn versions. The EXO series encoders are equipped with high accuracy optical sensing technology while EXM series encoders mount a robust ...

Kollmorgen servo motors are now available with its fourth generation SFD-M smart feedback device. Supplied at no additional cost over its earlier SFD models, this encoder delivers four times greater ...

Avago Technologies announced a high-resolution absolute optical encoder for high-performance servo and motor feedback applications.
