High-precision linear encoder for industrial measurement and automation applications.

LK18 Photoelectric Linear Encoder

Photoelectric absolute linear encoder LK18 has measuring length of up to 2 040 mm depending on customer demand, uses SSI, BiSS or
FANUC® α-αi serial interface and produces up to ±5 μm accuracy. The encoder can have an additional 1Vpp (20 μm) incremental output.
