DS-58-32
Absolute Position, Rotary Electric Encoder™
The DS-58-32 is a member of the DS series, based on Netzer Precision Electric Encoder™ technology. This state-of-the-art encoder technology offers many advantages, some unparalleled:
• Low profile (17 mm)
• Hollow, floating, shaft
• No bearings or other contacting elements
• High precision
• High tolerance to temperature, shock, moisture EMI, RFI and magneticfields
• Multiple protocol interface options
• Continuesoutput
Demanding application suited to the DS-58-32 include: Aerospace, medical, instrumentation, automation, etc.
