Shuttles are compact vehicles for automated use in high-density pallet warehouses. They independently transport goods and store them reliably on the right place. Therefore, they are relying on smart sensors for optimal performance.

Sensor solutions for pallet shuttles

Collision avoidance

To avoid collisions, the distance between the shuttles must be measured. For this purpose, time-of-flight distance measurement sensors are the right solution:

Your benefits:

  • Reliable detection of objects on the lane allows highest availability​
  • Compact sensors with extended sensing range up to 10 m on a reflector tape allow more flexibility for your shuttle design 
Poistioning of the pallet

Positioning of the pallet

Precise positioning of pallets close to each other is essential for optimum use of space. Time-of-flight distance measurement sensors are the fitting solution:

Your benefits:

  • Reliable detection of the pallet regardless of shape and material allows highest availability
  • Compact sensors with extended sensing range up to 2.5 m allow more flexibility for your shuttle design
Pallet shuttle compartment fine positioning

Compartment fine positioning

The precise positioning of the shuttle in front of the shelf compartment is essential. For this, photoelectric background suppression sensors are the fitting solution:

Your benefits:

  • Laser beam allows very precise object positioning up to 0.05 mm accuracy for high productivity​
  • Reliable detection thanks to ambient light immunity
  • Compact sensors allow more flexibility for your shuttle design​
Presence and position control of the pallet

Presence and position control of the pallet

To detect protrusion on shuttles and ensure uninterrupted operation a precise and reliable pallet positioning on the shuttle is required. For this purpose, photoelectric background suppression sensors are the right solution:

Your benefits:

  • Material independent pallet detection allows highest availability
  • Reliable detection thanks to ambient light immunity
  • 3D CAD integrated beam and qTarget  make engineering and commissioning easy

Shuttle speed monitoring

Continuous shuttle speed monitoring within the lane is key. Bearingless incremental encoders are the ideal solution for this:

Your benefits:

  • Compact shuttle design thanks to bearingless encoder that requires minimal installation space
  • Non-contact, wear-free sensing system for continuous operation 
Shuttle positioning

Shuttle positioning

The precise positioning of the shuttle within the lane is essential. Industrial absolute encoders provide the right solution for this:

Your benefits:

  • Compact shuttle design thanks to the smallest installation depth in the 58 mm class
  • Simple device integration thanks to the availability of all common interfaces
Zero position detection

Zero position detection

Reliable detection of the zero position on the pallet lift is required. Inductive proximity switches or photoelectric fork sensors are the solution:

Your benefits:

  • Miniaturized sensors allow more flexibility for your shuttle design
  • Contactless sensor principles for robust and wear-free design
Positioning of the shuttle at the lane end

Positioning of the shuttle at the lane end

For maximum use of the storage capacity a precise pallet positioning at the lane end is essential. Time-of-flight distance measurement sensors are the solution here:

Your benefits:

  • Precise positioning thanks to reliable detection of the lane end
  • Compact sensors with extended sensing range up to 2.5 m allow more flexibility for your shuttle design
