In response to frequent inquiries, we would like to provide you with detailed insights into the meticulous testing procedures employed for most of our sensors according to EN 60947-5-2 standards. Our commitment to quality assurance is reflected in the stringent shock and vibration testing conducted in accordance with EN 60947-5-2 standards.

Vibrations, Sinusoidal (acc. to IEC 60068-2-6):

  • Test Conditions:
    • Axes: 3
    • Frequency Range: 10-2000 Hz
    • Amplitude:
      • 1 mm for inductive, capacitive, magnetic, and ultrasonic sensors
      • 0.5 mm for opto-electric sensors
    • Duration: 1 octave per minute
    • Stability Time at Resonance Frequency or 55 Hz: 30 minutes per axis (totaling 90 minutes)

Single Shock (acc. to EN 60947-5-2):

  • Test Conditions:
    • 6 shocks to each axis
    • Acceleration: 30 g (300 m/s^2)
    • Shock Duration: 11 ms

Continuous Shock (acc. to IEC 60068-2-27):

  • 25g, 6ms, 2000 shocks to each axis

Random Vibration (acc. to IEC 60068-2-64):

  • Frequency Range: 20 - 2000 Hz
  • Acceleration: 10 g-rms
  • Duration: 1 hour and 40 minutes to each axis

These rigorous tests serve as a testament to our unwavering commitment to delivering sensors of unparalleled quality and resilience. Adhering to the standards set by EN 60947-5-2, our sensors undergo comprehensive evaluation under diverse conditions to ensure they meet and exceed industry benchmarks.

Humidity:

Our sensors undergo two distinct humidity resistance tests:

1. **DIN EN / IEC 60068-2-30 - Casing Test:**
   This test subjects the sensor casing to challenging conditions. The temperature undergoes a cycle from 25°C to 55°C with humidity levels maintained at 95 % - 98 %. Subsequently, the temperature is reduced back to 25°C. This entire process is repeated five times, ensuring the casing's resilience to varying levels of temperature and high humidity.

2. **DIN EN / IEC 60068-2-38 - Electronic Parts Test:**
   Focused on evaluating the electronic components, this test involves a temperature drop from 55°C to - 16°C, all while maintaining a humidity level of 95 % - 98 %. Once the temperature reaches -16°C, it then ascends to 55°C. Similar to the casing test, this cycle is repeated five times, affirming the robustness of the electronic parts under fluctuating temperatures and high humidity conditions.
