Performance highlights E603 Intrinsically safe large angle tilt sensor

The E603 is a highly accurate, intrinsically safe tilt sensor engineered for precise angle measurement in hazardous environments. Its inductive, non-contact sensing technology ensures high reliability and eliminates mechanical wear, offering a robust solution for demanding applications.

Usage conditions

Designed for continuous operation in explosive atmospheres (gas, vapor, or dust), the E603 meets Ex II 1GD specifications and can operate in temperature ranges from -20°C to +80°C. It delivers stable, linear output signals with infinite resolution and minimal noise (<0.02% FSO). The rugged stainless steel housing is sealed to IP67 and supports installation with a 4-pin M12 connector.

Possible applications

  • Tilt angle feedback in offshore or ATEX environments
  • Industrial robotics and automation
  • Safety-critical tilt monitoring systems
  • Tilt angle sensing on mobile and stationary platforms
  • OEM integration in hazardous area measurement solutions

Advantages of choosing this sensor

With configurable angle ranges from 15° to 160°, this sensor is tailored to each application. Its robust EMC compliance, industrial-grade connector options, and certification across multiple safety standards make it a top choice for engineers and system integrators seeking reliability in hazardous conditions.

Other important features

  • Response time: 250 ms at 20°C
  • EMC compliant (EN 61000-6-2, EN 61000-6-3)
  • Vibration resistance up to 10g, shock resistance 40g
  • Customizable cable options up to 1000m (5-wire recommended for >10m)
