NI40U-CP40-FDZ30X2 40mm Inductive Proximity Sensor IP67 Stainless DC 10-30V Industrial Switch

1. ​Dual-Channel Safety Proximity Sensor Overview​

The Turck NI40U-CP40-FDZ30X2 is an advanced inductive proximity sensor engineered for safety-critical industrial automation applications. Featuring a ​nickel-plated brass housing (NI40U suffix)​​ with ​IP67/IP69K protection, this device delivers an ​exceptional 40mm sensing range (CP40)​​ for ferrous targets. Its ​dual PNP outputs (FDZ30X2 designation)​​ provide redundant NO/NC channels meeting SIL 2/PL d safety standards per IEC 61508/ISO 13849. Operating across ​​-40°C to +85°C, the sensor incorporates ​cross-monitoring diagnostics​ to detect internal faults while resisting high-pressure washdowns (150 bar), oils, and vibration (10g). The M30×1.5 threaded design enables robust mounting in safety gates, robotic cells, and heavy machinery where redundant signal paths prevent dangerous machine failures. Integrated dual-color LEDs offer independent channel status indication.

2. ​Critical Technical Specifications​

• ​Sensing Performance:
  Range: 40mm for steel (Fe360) ±10%
  Target: Ferrous metals ≥1mm thickness
  Repeatability: ±0.5mm
• ​Electrical:
  Outputs: 2× PNP (NO+NC independent channels)
  Voltage: 10-55V DC / 20-250V AC
  Switching Current: ≤400mA per channel
• ​Environmental:
  IP67 (IEC 60529) / IP69K (ISO 20653)
  Temperature: -40°C to +85°C
  Shock: 100g (IEC 60068-2-27)
• ​Safety Ratings:
  SIL 2 (PFHD 1.2×10⁻⁸/h)
  PL d (Cat. 3 per ISO 13849-1)
• ​Mechanical:
  Housing: Nickel-plated brass
  Thread: M30×1.5
  Cable: PUR 2m (oil-resistant)

3. ​Safety-Critical Industrial Applications​

This sensor excels in high-risk automation scenarios:

• ​Robotic Workcells: Dual-channel safety door monitoring
• ​Press Brakes: Redundant guard position verification
• ​Automotive Assembly: Safety mat bypass prevention
• ​Packaging Lines: Muting sensor redundancy
• ​Material Handling: SIL 2-compliant pallet presence detection
• ​Metal Stamping: Dual-input light curtain monitoring
• ​Conveyor Systems: Emergency stop verification
• ​Machine Tools: Tool changer safety interlocks
  Its dual-channel architecture enables use in safety circuits up to PL d where single sensor failure must not compromise protection integrity, particularly in automotive and heavy machinery sectors.

4. ​Functional Safety Advantages​

• ​Dual-Channel Safety:
  Cross-monitored outputs detect internal faults

  60% diagnostic coverage (DCavg)

• ​Extended Sensing:
  40mm range allows barrier penetration
  ±15mm lateral tolerance alignment
• ​Environmental Resilience:
  Resists hydraulic fluids, coolants, and UV
  IP69K withstands 1500 psi washdowns
• ​Diagnostic Intelligence:
  Dual LEDs (green/red) per channel
  Fault memory via output pulsing
• ​Electrical Versatility:
  AC/DC universal voltage operation
  Short-circuit/overload protection
• ​Compliance Efficiency:
  Pre-validated SIL 2/PL d documentation
  TÜV-certified safety templates

5. ​Safety Operation & Diagnostics​

​Dual-Channel Logic:

1. ​Target Detection:
   • Ferrous metal enters 40mm range → field disturbance
2. ​Output Behavior:
   • ​NO Channel: Closes (sinks current)
   • ​NC Channel: Opens (stops sinking)
3. ​Cross-Monitoring:
   • ASIC compares channel response times

   • 5ms discrepancy triggers fault

4. ​Diagnostic Indicators:

   ​LED State​	​Condition​
   Green (both)	Normal operation
   Red (Channel 1)	Channel 1 fault
   Red (Channel 2)	Channel 2 fault
   Flashing Red	Cross-fault detected

​Safety Response:

• Outputs force safe state (NO open/NC closed) on fault
• Undervoltage lockout below 8V DC
• Automatic restart after fault clearance
