Precizika Metrology Linear Encoder Model L18C
The sealed linear encoder L18C 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. 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.
Two versions of output signals are available:
• L18C-A sinusoidal signals, with amplitude not smaller than 15 μApp, require an external subdividing electronics.
• L18C-F square-wave signals (TTL), with integrated subdividing electronics for interpolation x1, x2, x5, x10, x25, x50.
