Shaft encoders

The advantages of Hengstler encoders
The keywords here are technology and flexibility. Technology through the use of our optoasic's, where we have been able to replace up to 200 individual SMD components while increasing reliability. Flexibility with our building block concept, where we can offer over 1,000,000 different encoder versions from just 4 different sub-assembly classes.



What are encoders?
Incremental encoders are sensors capable of generating signals in response to rotary movement. In conjunction with mechanical conversion devices, such as rack-and-pinions, measuring wheels or spindles, incremental shaft encoders can also be used to measure linear movement. The shaft encoder generates a signal for each incremental change in position.
With the optical transformation, a line-coded disc made of metal, plastic or glass which is positioned on a rotary bearing, interrupts the infrared light ray emitted by the sender diode. The number of lines determines the resolution, i.e. the measuring points within a revolution. The interruptions of the light ray are picked up by the receptor element and electronically processed. The information is then made available as a rectangular signal at the encoder output.
