Atlas Copco TC-4000-P-PN-ESM
Model Series: TC-4000 Series (High-End Industrial Grade)
Product Overview:
The TC-4000-P-PN-ESM is a top-tier electric torque controller designed for high-precision fastening applications requiring real-time peak torque and angle monitoring with full statistical process control (SPC) capability. The ESM (Electric Screwdriver Monitoring) module enables complete gun-level data tracking.
Detailed content
Technical Specifications:

- Up to 1000 result storage with timestamp
- Ethernet-based remote diagnostics
- Multi-step tightening strategy programming (up to 10 steps)
Structural Characteristics:
- Aluminum alloy housing with anodized finish
- 7-inch TFT color touchscreen display
- Front-panel IP67-rated push buttons
- DIN rail or panel mounting option
Material Composition:
- Housing: Anodized aluminum alloy (AL6061-T6)
- Connectors: Gold-plated contacts for corrosion resistance
- Cable glands: Nickel-plated brass (IP68 rated)
Working Principle:
The controller continuously samples torque and angle signals from the electric screwdriver via a high-speed encoder. It compares real-time values against programmed targets. Upon reaching the set torque threshold or angle limit, the controller sends a stop signal to the tool, ensuring consistent fastening quality.
Key Advantages:
- Highest accuracy in the TC-4000 lineup (±1%)
- Full traceability for aerospace and automotive compliance
- Remote monitoring capability via Ethernet
- ESM module provides per-gun performance tracking
Applicable Industries:
Automotive assembly, Aerospace manufacturing, Heavy machinery, Wind energy, Rail vehicle production
Installation Requirements:
- Mount on DIN rail (TS35) or flush-mount panel cutout (140 x 110 mm)
- Ground connection required (PE terminal)
- Shielded cable recommended for noise environments
- Minimum 100 mm clearance around unit for heat dissipation
Usage Precautions:
- Do not exceed maximum rated torque of 4000 Nm
- Recalibrate torque sensor every 12 months or 500,000 cycles
- Keep display clean; avoid direct sunlight on screen
- Update firmware via Atlas Copco Connect software before production use
