    Linear encoders

    Sealed linear encoders are protected from dust, chips and splash fluids and are ideal for operation on machine tools.

    Exposed linear encoders operate with no mechanical contact between the scanning head and the scale or scale tape. Typical areas of application for these encoders include measuring machines, comparators and other precision devices in linear metrology, as well as production and measuring equipment, for example in the semiconductor industry.

    With incremental linear encoders,the current position is determined by starting at a datum and counting measuring steps, or by subdividing and counting signal periods. Incremental encoders from HEIDENHAIN feature reference marks, which must be scanned after switch-on to reestablish the datum. This process is especially simple and fast with distance-coded reference marks.

    Absolute linear encoders require no previous traverse to provide the current position value. The encoder transmits the absolute value through the EnDat interface or another serial interface.

    Length gauges from HEIDENHAIN feature integral guideways for the plunger. They are used to monitor measuring equipment in industrial metrology, and also as position encoders.

    For angle measurement, HEIDENHAIN provides a large selection of encoders that covers the entire range of accuracy requirements.

    Angle encoders
    The term angle encoder is typically used to describe encoders that have an accuracy of better than ± 5″ and a line count above 10000. These devices are used in applications such as NC rotary tables, swivel heads of machine tools, dividing apparatuses, high-precision angle measuing tables, precision devices in angular metrology, antennas and telescopes.

    Rotary encoders
    Rotary encoders from HEIDENHAIN serve as measuring sensors for rotary motion, angular velocity and also, when used in conjunction with mechanical measuring standards such as lead screws, for linear motion. Application areas include electrical motors, machine tools, printing machines, woodworking machines, textile machines, robots and handling devices, as well as various types of measuring, testing, and inspection devices.

    With incremental angle encoders and rotary encoders, the current position is determined by starting at a datum and counting measuring steps, or by subdividing and counting signal periods. Incremental encoders from HEIDENHAIN feature reference marks, which must be scanned after switch-on to reestablish the datum. Incremental rotary encoders with commutation signals supply the angular shaft position value – without requiring previous traverse – with sufficient accuracy to correctly control the phases of the rotating field of a permanent-magnet three-phase motor.

    Absolute angle encoders and rotary encoders require no previous traverse to provide the current position value. Singleturn encoders provide the current angular position value within one revolution, while multiturn encoders can distinguish between revolutions. Absolute angle encoders and rotary encoders from HEIDENHAIN provide the position values over an EnDat, SSI, PROFIBUS-DP or other serial data interface. The EnDat PROFIBUS-DP bidirectional interfaces enable automatic configuration of the higher-level electronics and provide moitoring and diagnostic functions. With programmable rotary encoders, the user can adjust various encoder functions and parameters from a PC with provided software.

    Magnetic Modular Encoders
    The robust ERM magnetic modular encoders are especially suited for use in production machines. Their large possible inside diameters as well as the small dimensions and compact design of the scanning head predestine them for:
    The C axis of lathes
    Spindle orientation on milling machines
    Auxiliary axes
    Integration in gear stages
    The signal period of approx. 400 µm and the special MAGNODUR procedure for applying the grating achieve the accuracies and shaft speeds required by these applications.

    Tool and Workpiece Setup and Measurement

    The TS workpiece touch probes from HEIDENHAIN help you perform setup, measuring and inspection functions directly on the machine tool.

    Tool measurement on the machine shortens non-productive times, increases machining accuracy and reduces scrapping and reworking of machined parts. With the tactile TT touch probes and the contact-free TL laser systems, HEIDENHAIN offers two completely different possibilities for tool measurement.

    Measuring Systems For Machine Tool Inspection and Acceptance Testing

    Machine tool performance from the point of view of compliances to tolerances, surface definition, etc., is determined essentially by the accuracy of machine movement.
