BI15-CP40-VP4X2-H1141 15mm Inductive Proximity Sensor IP67 Stainless DC 10-30V Industrial Switch

1. ​Compact Dual-Output Proximity Sensor Overview​

The Turck BI15-CP40-VP4X2-H1141 is a high-performance inductive proximity sensor engineered for industrial automation applications requiring redundant detection in space-constrained environments. Featuring a ​nickel-plated brass housing (BI15 suffix)​​ with ​M18×1 threading, this compact device delivers an ​exceptional 40mm sensing range (CP40)​​ for ferrous targets. Its ​dual PNP outputs (VP4X2 designation)​​ provide independent normally open (NO) channels for redundancy or multi-point control. The "H1141" suffix specifies an ​M12 4-pin quick-disconnect connector​ for rapid installation. Certified for ​IP67/IP69K protection, it withstands high-pressure washdowns (150 bar), oils, and temporary submersion while operating across ​​-40°C to +85°C. Designed for automotive, material handling, and packaging machinery, this sensor enables reliable position verification in compact spaces where dual-channel monitoring prevents costly downtime.

3. ​Space-Constrained Industrial Applications​

This sensor excels in compact machinery requiring redundancy:

• ​Robotic Welding Cells: Dual-position verification of electrode holders
• ​Packaging Machinery: Redundant detection of film feed rollers
• ​CNC Tool Changers: Dual-confirmation of tool magazine positions
• ​Pharmaceutical Fillers: Backup sensing for stopper placement systems
• ​Conveyor Merge Points: Dual-channel package tracking
• ​Automotive Assembly: Safety gate position redundancy
• ​Textile Machinery: Thread break detection with backup signaling
• ​Electronic Assembly: Dual PCB presence verification
  Its M18 compact design fits tight spaces like motor end caps or gearbox housings, while dual outputs enable safety interlocks per ISO 13849-1 PL c standards in applications where single sensor failure could cause jams or safety hazards.

4. ​Functional Advantages​

• ​Redundancy in Minimal Space:
  Dual independent outputs in 40mm length
  M12 connector saves 60% panel space vs terminal blocks
• ​Extended Sensing Capability:
  40mm range detects misaligned targets (±10mm lateral tolerance)
  Non-flush mounting capability (Factor 1)
• ​Environmental Resilience:
  Nickel-plated brass resists coolants/solvents
  IP69K withstands 1500 psi CIP washdowns
• ​Electrical Versatility:
  AC/DC universal voltage operation
  Short-circuit/overload protection per channel
• ​Diagnostic Visibility:
  Dual green LEDs indicate independent output status
  Quick-disconnect connector enables tool-free replacement
• ​Safety Compliance:
  SIL 2 architecture with diagnostic coverage >60%
  PL c capable per ISO 13849-1

5. ​Dual-Channel Operation & Diagnostics​

​Sensing Logic:

1. ​Target Detection:
   Ferrous metal enters 40mm range → electromagnetic field disturbance
2. ​Independent Output Control:
   • Channel 1: PNP switches on detection
   • Channel 2: Simultaneous switching for redundancy
3. ​LED Indication:
   • Solid Green (each): Output active
   • Off: No target/output inactive
4. ​Fault Response:
   • Single channel failure doesn't affect the other
   • Automatic reset after fault clearance

​Safety Integration:

• ​Cross-Monitoring:
  ASIC detects output discrepancies >5ms
  Forces both channels safe (open) on internal fault
• ​Environmental Testing:
  500hr salt spray resistance (ISO 9227)
  Vibration immunity: 10-55Hz @ 1.5mm amplitude
• ​Connector Safety:
  M12 connector provides IP67 mating integrity
  Breakaway force >50N prevents accidental disconnection
