The LM10 features a compact sealed readhead that rides at up to 1.5 mm from the self-adhesive magnetic strip scale, with up to 100 m travel.
Simple to install, the LM10 features an integral set-up LED on the readhead, wide installation tolerances and an applicator tool for the adhesive-backed magnetic scale. A bidirectional reference is provided that can be actuated either by a preset mark integrated within the scale or by adding a reference sticker on top of the scale with the help of a self aligning installation tool.
The encoders come in digital or analogue output variants and offer a range of customer selectable resolutions 1 µm, 2 µm, 5 µm, 10 µm, 20 µm and 50 µm. At 1 µm the LM10 offers a maximum velocity of 4 m/s.
Engineered for extreme service, the solid-state LM10 linear encoders operate from -20 °C to +85 °C, have water-proof sealing to IP68, and are highly resistant to shock, vibrations and pressure. The robust magnetic scale is also resistant to a range of chemicals commonly found in industry. The non-contact, frictionless design eliminates wear while reducing hysteresis for high precision at high speeds and acceleration.
LM10 encoders bring reliable solutions to tough, hard-working applications including woodworking, stone-cutting, sawing, metalworking, textiles, packaging, plastics processing, automation and assembly systems, water-jet cutting, and electronic chip/board production. |

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
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.

| All series of digital readouts and linear scales produced by CARMAR are designed with five bearings on the slide for superior repeatability, high slide accuracy and long service life. The scale frame is manufactured from anode treated aluminum alloy and comes with a hard chrome scale head treated for corrosion resistance. The signal wires employ a multiple layer braided net and are guarded with stainless steel shades for waterproof and anti-interference performance. The pitch of line grating is 20 microns and is fitted with ABS reference signals at the centre of the measuring length and 20 mm to each end, as standard. The response speed is 60 m/min. |
|
| Absolute linear encoders create a unique position signal that is available anywhere along travel with the exact position being read after power cycling. |

Our magnetostrictive linear sensors sense linear movements without contact and wear free. Linear sensors with multi magnet function can (partially) detect even up to 16 positions simultaneously.
Linear sensor in
stainless steel rod
For installation in hydraulic cylinders and hydraulic presses, tool and transfer machines, injection molding and packaging machines, storage etc.
The TR standard for magnetostrictive linear sensors is the device with pressure resistant stainless steel rod. |
|
| The enclosed models are best suited for harsh environments. The sealing lips on the extrusion keep out coolants and contamination. For applications where the Linear Encoders are used in very harsh environments, there are methods of extra protection (IP 64) beyond the enclosed unit´s standard set of sealing lips. |

The non-contact open measuring systems are for high displacement velocities and high accuracies, commonly used in clean environments.
Non-contact open encoders rely on the air gap between the encoder head and scale to be uniform over the measuring range. The flatness of the mounting surface and the parallelism of the machine guideway is important.
Depending on the version of the measuring system, two different measuring scales are available:
glass (partially ROBAX glassceramic) or steel . |
|
| Incremental encoders do not generate a unique signal and is zeroed after power-down. They rely on crossing an index or home signal (sometimes multiple index marks are used) prior achieving absolute position. |
