Many applications require a simple, cost effective solution for accurate positioning. IXARC incremental encoders provide high resolution measurement using an incremental interface. They are available with common configurations such as A, B, Z, and inverted signals available as HTL (Push-Pull) or TTL (RS422).
Incremental rotary encoders generate an output signal each time the shaft rotates a certain angle. The number of signals (pulses) per turn defines the resolution of the device. The incremental encoder does not output an absolute position, which makes the internal components of the encoder much simpler and more economical.
Besides position tracking, incremental encoders are often used to determine velocity. The position in relation to the starting point can be calculated by counting the number of pulses. The velocity can be retrieved by dividing the number of pulses by the measured time interval.
Technology wise these encoders are available in two types:
Magnetic technology provides a compact, robust and cost-efficient angular sensing using an innovative Multiturn technology and a Hall-sensor.
A key component of optical rotary encoders is a code disk mounted on the encoder shaft. This disk is made of unbreakable plastic that has a concentric pattern of transparent and opaque areas.
We introduce powerful new programming capabilities and tools for their IXARC series of rotary encoders. Programmable incremental encoders have proven to be popular over the past several years since the measurement characteristics of the device (number of pulses per rotation, output level, etc.) can be modified through a software update without requiring any changes to physical components.
