Absolute linear encoder SHG-A4

RS-4855 VDCstainless steel

RS485 meets the requirement of a multi-point communication network, which can have up to 32 drivers and 32 receivers on a single two-wire bus. A key feature is the ability to address individual devices. This model can be ordered with unique address tags. Developed to meet a wide range of feedback applications, the SHG-A4 absolute linear encoder provides a true absolute position immediately upon power-up. The encoder does not use batteries or static memory to retain the positional data. True position can be reacquired once power is applied, regardless of duration or power-off movements.
