Ensures 100% domestically sourced components for every part of the product.
High-precision magnetic sensing technology; available as singleturn or multiturn encoder.
RS485 free communication interface or Modbus-RTU interface.
Optional incremental signal output: TTL or HTL.
Singleturn resolution up to 21 bits; multiturn up to 14 bits.
Exceptional shock and vibration resistance.
Features reverse-polarity and short-circuit protection to effectively minimize the impact of installation errors on the encoder.
