Electrical Connection: M12 5-Pin Connector (A-Coded) or M23 12-Pin (Custom)

Multi-Turn Capability: None — Single-Turn Only (Position resets on power cycle if power lost mid-revolution, but absolute within one revolution at all times)

Key Features:

• BiSS-C protocol provides CRC error checking, alarmed position flag, and bidirectional communication over a single cable pair
• Hollow shaft design allows direct mounting over motor shaft — zero additional backlash
• 12-bit resolution provides 4096 unique positions per revolution with <1 arc-minute accuracy
• Update rate up to 200 kHz enables high-bandwidth servo loops
• Operates from -40°C to +85°C — rated for harsh industrial environments

Applicable Industries: Servo Motor Feedback, Robotics Joints, CNC Spindles, Medical Imaging Gantries, Antenna Positioning

Installation Requirements:

• Mount encoder over shaft using 6 mm ID clamping hub — tighten to 3 Nm
• Align encoder shaft to motor shaft within 0.05 mm TIR (Total Indicated Runout)
• Cable: Use shielded twisted pair, 5 VDC power and BiSS-C data on same M12 connector
• Do not exceed 6 VDC on supply pins

Usage Notes:

• Single-turn only — for multi-turn applications, use Kollmorgen 63033 Series (Multi-Turn Absolute)
• BiSS-C requires master (drive) to initiate communication — encoder does not auto-transmit
• Do not apply axial load to shaft — use thrust bearing on motor side
