Kollmorgen CE03250
Overview:
The CE03250 is a pre-manufactured cable assembly from Kollmorgen’s CE cable series, designed for connecting Kollmorgen servo drives to AKM/AKM2G series frameless or housed servo motors, specifically carrying power, encoder signals, and brake signals in a single shielded assembly. The model code indicates: CE (Cable Ensemble) + 032 (32 conductors or specific pin configuration) + 50 (5.0 meter length or 50-series variant). This cable is a factory-terminated, tested assembly that guarantees signal integrity and mechanical reliability.

Material Composition:
- Conductors: Oxygen-free high-conductivity (OFHC) copper, tinned for corrosion resistance
- Insulation: Cross-linked polyethylene (XLPE) for signal wires, PVC for power wires
- Shield Layer 1: Tinned copper braid (85% coverage)
- Shield Layer 2: Aluminum/Mylar foil (100% coverage)
- Outer Jacket: Polyurethane (PUR) — resistant to oils, coolants, and abrasion
- Connectors: Nickel-plated brass shell, gold-plated contacts (M23 standard)
Structural Features:
- Round cable geometry with integrated drain wire
- Strain relief boots at both connector ends (minimum 30 mm)
- Color-coded inner wires per Kollmorgen pinout standard
- Pre-tested for continuity, insulation resistance (>100 MΩ), and shielding effectiveness (>60 dB)
Working Principle:
The cable transmits three-phase motor power (U, V, W + PE), encoder signals (EnDat 2.2 or Hiperface differential pairs), brake power (24 VDC), and temperature sensor signals (PTC/NTC) between the servo drive and motor. The double shielding prevents electromagnetic interference (EMI) from corrupting high-speed encoder data, which is critical for maintaining position accuracy at high servo update rates.
Advantages:
- Factory-terminated and tested — eliminates field wiring errors
- Double-shielded — maintains signal integrity in high-EMI environments (near VFDs, welders)
- PUR jacket — survives harsh industrial environments (oils, coolants, abrasion)
- Exact length — no excess cable clutter in the machine
- Full traceability — part-numbered for inventory and maintenance
Applicable Industries:
All Kollmorgen servo motor applications: CNC machines, robotics, packaging, printing, semiconductor, medical devices.
Installation Requirements:
- Route cable away from high-current power cables (minimum 100 mm separation)
- Do not exceed minimum bend radius — kinking will damage internal conductors
- Use cable clamps at both ends and at intervals not exceeding 500 mm
- Connect drain wire to chassis ground at one end only (drive end preferred)
Usage Precautions:
- Do not pull cable by the connector — always grip the jacket
- Replace immediately if outer jacket is cut, crushed, or shows signs of chemical attack
- Do not operate in temperatures exceeding 80°C continuous
- Verify pin-to-pin continuity before installation — do not assume factory test equals field condition after shipping
