LASERSCALE™
High accuracy linear and rotary scales
High-speed response, superior accuracy, and high environmental resistance is featured in the LASERSCALE™, an exposed encoder from Sony. Because there is no contact between the scanning head and the scale, mechanical backlash (hysteresis) is eliminated. LASERSCALE™ measures displacement by monitoring the phase change of a semiconductor laser beam as it passes through a hologram grating.

The sealed linear encoder is used to convert linear displacements of machine key components into electrical signals containing information about the value and direction of the displacement.
The encoder consists of a glass grating scale installed into a rigid hollow housing and a ball-bearing-guided reading head. To be able to work in harsh environments such as lubricants and chips, the encoder has sealing lips. Filtered air can be supplied into the housing of the encoder for extra protection.

IDEACOD, the leader of the rotary sensor, offers also solutions with linear sensor. 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..

Sensor Head in slide carrier with sealed high aluminium profile
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.
