Product catalog summary
Overview: The document provides technical specifications and features of the FNC AC 58B Bus Cover Series, focusing on its electrical and mechanical design, as well as its capabilities and accessories.
Specifications:
  • Electrical Ratings: Voltage supply ranges from 5.5VDC to 30VDC, with options for 4.75VDC to 5.5VDC and 8VDC to 30VDC. The device features magnetic sensing, single turn resolution of 12 to 19 bits, and multi-turn resolution of 4 to 32 bits.
  • Mechanical Design: The encoder has a flange diameter of 58 mm, with shaft loading capacities of ≤140 N axial and ≤240 N radial. It operates at speeds up to 10,000 rpm and has a starting torque of ≤0.025 Nm (IP 67). The housing is made of aluminum, and the shaft is stainless steel.
  • Protection and Durability: The device is protected against short circuits and reverse polarity, with an IP54 or IP65 protection rating. It is resistant to shock (200 g, 6 ms) and vibration (30 g, 10-2000 Hz).
Features:
  • Modular fieldbus interfaces supporting Profibus and CANopen®.
  • Absolute accuracy of ±0.35° with a resolution of 9 to 16 bits per turn.
  • Programmable parameters include steps per revolution, number of revolutions, preset, scaling, and rotating direction.
  • Diagnostic functions for position or parameter errors, with status indicators using integrated RED & GREEN LEDs.
Accessories: The document lists connectors, cables, mounting couplings, and accessories, including CRM2312R M23 12 poles female connector, PF481010 metal coupling, and SF58B spring.
Compliance and Standards: The encoder complies with DIN EN 60068-2-6, DIN EN 60068-2-27, DIN EN 61000-6-2, and DIN EN 61000-6-4 standards, and has CE approval.
