Sensors - System description

  • Inclination sensors with CAN or analogue interface.
  • Inductive sensors with IP 67 and IP 69K.
  • Pressure sensors with a robust measuring cell for mobile hydraulics.
  • Highest shock and vibration resistance.
  • Extended temperature range of -40...85 °C.

Sensors for mobile applications
In automation technology sensors are the “sense organs” of the control systems. Sensors are also used in mobile machines and installations. In contrast to devices for industrial automation, the demands on sensors for mobile applications are much higher. As they are mounted in exposed positions they have to meet special requirements. Sensors are generally differentiated between sensors with a built-in CANopen interface and sensors with binary or analogue output stages which are connected directly to controllers or I/O modules.

Special features
Sensor components such as the sensing face or housing material are adapted to the rough operating conditions. The devices are designed to ensure highest shock and vibration resistance. Corrosion-resistant M12 connectors with gold-plated contacts increase their lifetime. The sensors have a temperature range of -40...85 °C so that they can operate reliably in extremely cold conditions and when installed next to hot engines. Moreover, the devices are insensitive to rapid temperature changes. A voltage range of up to 10...60 V for mobile sensors ensures that even high fluctuations of the on-board system do not affect the function. To comply with the ever increasing EMC requirements in mobile applications the devices feature an increased EMC resistance. All sensors hold an e1 type approval. With this approval of the German Federal Office for Motor Traffic they are allowed for use in road vehicles without expiry of their operating permit.
