Rotary encoders

LTN

Technology and flexibility are key characteristics of our incremental and absolute rotary encoder series ICURO and ACURO. Monolithically integrated opto-ASICS will reliably replace up to 200 SMD components. Thanks to the modular construction, users can select the required configuraion from over two million possible rotary encoders.

Incremental encoders convert an angular position optically into an electronical signal. Those highly precise signals are a must-have for high-end position controls.

Typical applications for incremental encoders include:
– machine tools
– elevators and escalators
– automatic doors and access systems
– fans
– packaging machines
– paper processing
