A look at practical sensor applications
Presence check of objects in processes independent of the specific object position
Extremely fast and precise position detection, even of the smallest objects
Detection of objects also across large distances
Reliable count of objects, also with the smallest distances
Recognition of different object materials, colors, and contrasts
Object detection, even with transparent, uneven, punctured, or rough surfaces
Detection of objects through the smallest openings
Technology
Diffuse sensors with background suppression
- Based on the triangulation principle
- Transmitter and receiver in one device
- Evaluation of the angle of incidence of the light
- Detection regardless of the object’s color, surface, or background
The light barrier without a reflector - Smart Reflect
- Beam interruption between the sensor and e.g. machine part
- Very reliable object detection regardless of form, color, and surface
- Maximum operating safety, no standstill caused by the dirty or defective reflector
Diffuse sensors with intensity difference
- Light re-emitted from the target object triggers the sensor
- Transmitter and receiver in one device
- Dependent on object color, surface, and degree of gloss
Retro-reflective sensor
- Beam interruption between the sensor and the reflector
- Transmitter and receiver in one device
- Detection regardless of the object’s color or surface
- Detection of glossy and reflective objects thanks to the polarization filter
Through-beam sensor
- Beam interruption between the transmitter and the receiver
- Transmitter and receiver are located opposite each other in separate housings
- Detection of objects over long distances
- Highest excess gain
4 light sources
- Standard LED: Diffuse light spot for object recognition
- Baumer PinPoint LED: Small, homogeneous light spot with sharp edges
- Infrared LED: Invisible light beam
- Laser: Focused, easily visible light beam
