Encoder

Product Details:

Absolute shaft encoders assign a unique, digitally encoded signal to each individual measured increment. Single turn as well as multi - turn types are available.

The special feature of absolute shaft encoders is that they assign a unique, digitally encoded signal to each individual measured increment. The method of transducing in these absolute encoders prevents erroneous readings whether by a power failure, or by a transient malfunction. After the absolute shaft encoders are switched on again, or power is restored, the position can be read out. Absolute shaft encoders are not necessary to move to a reference position, as it is for shaft encoders of the incremental type.

Example of application for absolute encoder

• Overhead support robots
• Ventilation flaps
• Spinning machines
• Conveyor belts
• Cam controllers
• Injection moulding machines
• Packaging machinery
• Extruders
• Folding machines
• Printing machines
• High lift storage systems
• Stamping machines

Absolute shaft encoders generate a signal for each incremental change in position. Encoder diameter ranges from 30 to 76mm with push - pull / push - pull complimentary/ line driver (RS422) outputs are available.

With the optical transformation, a line coded dise made of metal plastic or glass and positioned on a rotary bearing interrupts the infrared light ray emitted by gallium arsenide sender diode. The number of lines determines the resolution, i.e. the measuring point within a revolution. The interruptions of the light ray are sensed by the receptor element and electronically processed. The information is then made available as a rectangular signal at the encoder output.
