P603 Intrinsically safe large angle tilt sensor

High-performance inductive tilt sensor with customer-specific angle range, designed for industrial machinery and scientific feedback tasks.


Key features

  • Non-contact inductive sensing for extended lifetime
  • Factory-set angle from 15° to 160°
  • Rugged stainless steel and aluminum construction
  • High accuracy (≤ ±0.25% error up to 100°)
  • IP67 environmental sealing
  • Wide range of voltage and current output options

Performance highlights P603 Inductive inclination sensor

The P603 tilt sensor delivers reliable high-resolution angle feedback using non-contact inductive technology. It features outstanding linearity, low hysteresis (≤ ±0.25% up to 100°), and exceptional stability across a wide temperature range. With an MTBF of 350,000 hours and noise below 0.02% FSO, it’s engineered for industrial-grade reliability.

Usage conditions

This sensor performs optimally in environments ranging from -20°C to +85°C, with storage tolerances up to -40°C to +125°C. It is vibration and shock resistant (10 g, 40 g), and compliant with EMC standards EN 61000-6-2 and EN 61000-6-3.

Possible applications

  • Tilt measurement on industrial machinery
  • Positioning feedback for mobile equipment
  • OEM solutions in harsh environments
  • Structural monitoring systems
  • Scientific instrumentation

Advantages of choosing this product

The P603 is ideal for OEMs seeking cost-effective, rugged, and customizable tilt sensors. It combines compact form factor, selectable output options (voltage or current), and IP67 protection in a robust package designed for demanding environments. Its flange mounting and registration mark simplify alignment and installation.

Other important features

  • 4-pin M12 connector with optional cable length
  • Ratiometric, ±5V, ±10V, 0.5–9.5V, 4–20mA outputs
  • Rotational calibration flexibility (15° to 160°)
  • Custom Z-coding output characteristics
  • Available 3D models (.STEP/.IGS)
