Linear encoders

Linear encoders from HEIDENHAIN measure the position of linear axes without added mechanical intervention, letting your machines attain exceptional positioning accuracy and machining speed.

Linear encoders

Linear encoders measure the position of linear axes without intervening mechanical elements. This eliminates a series of potential error sources such as backlash, pitch error, or heating of the recirculating ball screw. Wherever rigorous position accuracy and high machining speeds are needed, linear encoders are essential.

• Sealed linear encoders

Sealed linear encoders feature optimal protection from dust, chips, and splash water. They are especially ideal for use in manually operated machine tools and also in numerically controlled machine tools.

• Exposed linear encoders

Exposed linear encoders have zero mechanical contact between the scanning head and the scale or scale tape. Applications include production and measuring equipment in the semiconductor industry, as well as pick-and-place machines and direct drive systems.

Angle encoders

Position your rotational axes at high accuracies on the order of a few arcseconds. HEIDENHAIN has the ideal angle encoder for your application, whether sealed, modular or highly integrated with bearings.

Angle encoders from HEIDENHAIN: a solution for every rotary axis

HEIDENHAIN angle encoders enable high-accuracy angular measurement down to a few arcseconds. Various design options offer the optimal solution for any application: sealed versions for high robustness, modular solutions for maximum flexibility in the application, and angle encoder modules with an integrated precision bearing. As a result, process reliability and positioning accuracy are always perfectly matched to the given scenario.

• Angle encoders with integral bearing

Thanks to their very high system accuracy, angle encoders with an integral bearing are ideal for demanding applications such as machine tools and printing machines.

• Modular angle encoders

These angle encoders can be perfectly matched to the application, offering a choice of optical or magnetic scanning and numerous combinations of circular scales, scale drums, and scanning heads.

Touch probes and vision systems

How can you reduce setup times, boost machine-tool uptimes, and ensure process reliability for high manufacturing quality? With HEIDENHAIN touch probes and camera systems for tool and part measurement.

• Workpiece touch probes

The HEIDENHAIN workpiece touch probes enable setup, measurement, and inspection functionality inside the machine tool. When the stylus is deflected upon contact with a workpiece surface, a switching signal is sent to the control via cable, radio or infrared transmission.

• Tool touch probes

The HEIDENHAIN tool touch probes let you measure your tools efficiently and reliably. Tool measurement reduces scrap, minimizes rework, and cuts down on idle time while raising machining accuracy.

• Vision systems

The HEIDENHAIN vision system allows you to monitor tools for breakage and wear during machining. Individual teeth or the entire tool can be inspected for fast detection of damaged and worn tools. 

Signal converters

HEIDENHAIN signal converters adapt encoder signals to the interface requirements of your application's downstream electronics. They can even process additional sensor signals as needed.

Signal converters: greater flexibility for your applications

The signal converters from HEIDENHAIN let you flexibly adapt the encoder signal interfaces to the requirements of your applications. For some applications, additional signals, such as from temperature sensors, are processed and forwarded to the subsequent electronics.

• Adaptation to interfaces

The signal converters from HEIDENHAIN adapt the encoder signals to the interface, thereby boosting compatibility with the subsequent electronics. For greater flexibility in the application, signals can be interpolated, and different designs can be selected (e.g., housing, connector, top-hat rail, or built-in version).

• Angular measurement with greater accuracy

Benefit from real-time position calculation based on two scanning heads from rotatory HEIDENHAIN encoders without negative effects on the control loop. The EIB 1500 can compensate for errors such as shaft runout or the eccentric scale mounting of modular angle encoders.
