Precizika Metrology Linear Encoder Model L18T

The sealed linear encoder L18T is used to convert linear displacements of key machine components into electrical signals containing information about the value and direction of the displacement. The difference from encoder L18 series is that it has the other housing fixation and more stable thermal behaviour.

The encoder consists of a glass scale installed into a rigid hollow housing and a ball-bearing-guided reading head. To be able to work in harsh environments (lubricants and chips), the encoder has sealing lips. Filtered air can be supplied into the housing of the encoder for extra protection.

The photoelectric unit of the reading head generates sinusoidal micro-current or TTL square-wave (standard RS422) output signals.

Three versions of output signals are available:

• L18T-A - Sinusoidal signals, with amplitude approx. 11 μApp, require external subdividing electronics.

• L18T-AV - Sinusoidal signals, with amplitude approx. 1 Vpp, require external subdividing electronics.

• L18T- F - Square-wave, with integrated subdividing electronics for interpolation x1, x2, x5, x10, x 25, x50.
