Magnetic Linear Encoder

Magnetic absolute linear encoder MK has measuring length of up to 50.000 mm, accuracy can reach up to ±35 μm. The encoder has two versions of serial interface – SSI or BiSS C, but optionally it can have 2 an- alog sinusoidal signals with phase shift 90°C and amplitude approx. 1Vpp.
