Precizika Metrology Linear Encoder Model L18B

The sealed linear encoder L18B 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 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.

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:

• L18B-A - Sinusoidal signals, with amplitude approx. 11 μApp, require an external subdividing electronics.

• L18B-AV - Sinusoidal signals, with amplitude approx. 1 Vpp, require external subdividing electronics.

• L18B-F - Square-wave signals, with integrated subdividing electronics for interpolation x1, x2, x5, x10, x25, x50.
