Ensures 100% domestically manufactured components for every part of the product.
High-precision magnetic sensing technology; available as singleturn or multiturn encoder.
SSI interface with clock frequency up to 2 MHz.
Optional additional incremental signal output: TTL or HTL.
Singleturn resolution up to 21 bits; multiturn up to 14 bits.
Exceptional shock and vibration resistance; high protection rating up to IP68.
Equipped with reverse-polarity and short-circuit protection, effectively reducing the impact of installation errors on the encoder.
