Notes:

1) Where measurement conditions have not been specified precisely, the conditions used were as follows: (connected to the controller) supply voltage 24 V DC, ambient temperature +20 ℃ +68 ℉, MZBC mode (adjustment unit: width of 100 μm 3.937 mil), unit light receiving time 100 μs, average number of samples 64, measurement center distance, and target object is a white, light-diffusing object.

2) It is a value in which the sensor heads connected to a controller Ver. 2.00 or higher.

3) The value is the average of height measurement in full width at the measurement center distance.

4) This is the measurement value of a pin gauge rounded surface in the edge position measurement (start of falling edge) calculation setting. The measurement object: white ceramic pin gauge (ø10 mm ø0.394 in), unit light receiving time: 200 μs, measurement value extraction: base light intensity control, average number of samples: 64, width smoothing: ±4, all others are the initial settings.

5) Value represents the error in comparison with the ideal line of height measuring range (full scale) for the height measurement of the measurement center position in the width direction. The value in the specifications is the value within ±7.5 mm ±0.295 in of the height measuring range.

6) This product complies with 21 CFR 1040.10 and 1040.11 Laser Notice No. 50, dated June 24, 2007, issued by CDRH (Center for Devices and Radiological Health) under the FDA (Food and Drug Administration).

7) This size applies when using measurement center distance and is defined as 1/e2 (13.5 % approx.) of the center light intensity. Leaked light occurs outside of the defined range; sensing performance may be affected when the reflectance around the detection point is higher than that detection point.

FAQs

What does a laser displacement sensor do? ›

A laser displacement sensor can generate precise 2D and 3D surface measurements, including an object's height, width, angle, area, and position. Laser displacement sensors fall into three primary types: linear profilers, linear displacement sensors, and area-scan displacement sensors.

What is the fastest laser sensor? ›

The AR550 high speed laser sensor is Acuity's fastest triangulation device for dimensional and distance measurement. At sampling rates up to 70kHz, these sensors are typically used for applications that demand high speed such as vibration measurements, scanning of roads, vehicle crash test, and ballistic measurements.

What are the pros and cons of laser sensors? ›

Pros: Excellent distance capabilities, very lightweight, excellent accuracy. Cons: Single point measurements, eye safety concerns. Considerations: Laser signals require a direct line of sight and will penetrate glass and water, so these glass or water are difficult to detect using laser technology.

What are the disadvantages of laser flow sensor? ›

Difference between Red & Blue Laser Sensors (Advantages & Disadvantages)
Red LaserBlue Laser
DisadvantagesHigh noise for high temperature applications Limited applications when measuring on diffusive surfacesExpensive Low intensity laser, not suitable for dark surface

What is the purpose of a displacement sensor? ›

Displacement sensors (displacement gauges) are used to measure the movement of an object and the occurrence of a reference position. The displacement sensor can be used to measure amplitude to determine the height, thickness, and width of an object in addition to the range of motion.

How does the laser sensor work? ›

A laser sensor is an electric device that uses a focused light beam to detect the presence, absence, or distance of an object. The light that a laser sensor emits is a small bright dot, similar to a laser pointer. This dot is bright enough to be easily seen even in direct sunlight.

What are the advantages of laser distance sensor? ›

High Accuracy:

They are ideal for applications that require exact measurements. Their accuracy ensures dependable data for critical tasks. These sensors find application in various industries and fields where precision is essential. The laser beam emitted by the sensor allows for a focused and narrow measurement area.
