Photoelectric Linear Encoders - Modular Photoelectric Sealed Linear Encoder

L50

Modular photoelectric sealed linear encoder L50 has measuring length from 3240 mm up to 30040 mm. The encoder is used to convert linear displacements of key machine components into electrical signals containing information about the value and direction of the displacement. The encoder determines position by detecting light reflected of a metal band. Metal band with 40 µm pitch scale is fixed in rigid aluminium housing with protection lips. The encoder consists of several separate rigid modules with length up to 2.0 m, which are joined together, and reading head. Two versions of output signals are available :

  • L50-AV - Sinusoidal signals, with amplitude approx. 1 Vpp, require external
  • subdividing electronics. Resolution 0.1 µm is possible with respective external electronics.
  • L50-F - Square-wave signals, with integrated subdividing electronics for interpolation x1, x2, x5, x1 O.

Modular sealed photoelectric linear encoder L23 has measuring length up to 20 meters and more on special order. The 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 operates in reflected from metal band light beam. Metal band with made on its surface grating scale is fixed in rigid aluminium housing with double protection lips. The encoder consists of several separate modules with length up to 3,0 m, which are jointed together, and reading head. The standard encoder has three square-wave TTL output signals : 2 main signals, shifted by 90 degrees and one reference signal.


ABSOLUTE ROTARY ENCODER

Absolute singleturn and multiturn (battery buffered) solid shaft rotary encoders are used for generation of coded output signals which provide information about controlled object absolute position. In singleturn version rotary encoder AK36 has resolution from 9 up to 21 bit per revolution. Output signals interface is BiSS C or SSI. Operating principle is photoelectrical. In multiturn version AK36 has singleturn resolution from 9 up to 21 bit per revolution with 12/16120/24 bit resolution of multiturn counter on BiSS C interface. With SSI interface the encoder AK36 has resolution from 9 up to 21 bit per revolution with 9 up to 40 bit resolution of multiturn counter. Battery is placed inside of encoder. Operating principle is photoelectrical and magnetic. Absolute encoder is intended to use in robotics industry, automated and automatizated lines in industry, control devices of equipment and machines, various control systems, precise machine tools and others.
