Laser Sensors

11 sensors from 3 manufacturers

Laser sensors use a focused beam of coherent light for precise distance measurement and object detection. They offer high accuracy and small spot sizes, making them suitable for applications requiring fine resolution.

This catalog currently includes 11 published laser sensors from 3 manufacturers. Listed prices range from $197.50 to $540.00.

How It Works

A laser sensor emits a narrow, focused beam of coherent light toward a target. The sensor measures either the time-of-flight of the reflected light or the position of the reflected beam on a detector. The small spot size allows precise measurement of small targets or specific points on larger objects.

Typical Applications

• Precision distance measurement in manufacturing
• Detection of small or thin targets
• Positioning and alignment verification
• Thickness and dimension measurement
• High-speed object detection on production lines

Key Selection Considerations

• Spot size at the target distance determines minimum detectable feature size
• Target surface properties (color, reflectivity) affect measurement reliability
• Measurement range and accuracy are typically trade-offs
• Laser class and safety requirements vary by application
