L18B linear encoder
L18B linear encoder can measure length of
up to 3,240mm.
- maximum accuracy of ± 5 μm for each meter within the ML
- grating periods of ± 20 μm, ± 40 μm.
The sealed 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
