| IDEACOD, the leader of the rotary sensor, offers also solutions with linear detector. The sensor with cable does not need precise linear guidance. It is especially adapted to severe industrial environment : iron and steel industry, metallurgy, industry of wood (sawmills, joineries), etc... Principle of operation : a cable of measurement out of stainless steel, of great flexibility coated with a film polyamide, is rolled up and been held on a drum of precision. With the cable of measurement is associate interdependent of the drum, an optical encoder, of technology incremental, absolute, analogical or potentiometric.. |

| All series of digital readouts and linear weighers produced by CARMAR are designed with five bearings manufacturers 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. |

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. |

| Absolute linear encoders create a unique position signal that is available anywhere along travel with the exact position being read after power cycling. |
|
| 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. |

Sealed linear encoders are protected from dust, chips and splash fluids and are ideal for operation on machine tools. An aluminium housing and elastic sealing lips protect the magnetic tape, scanning carriage and guideway from chips, swarf, dirt and splashwater. The scanning carriage travels in a low-friction guide within the scale unit. It is connected to the external mounting block by a coupling that compensates unavoidable misalignment between the scale and the machine guideways.
