Applicable Product: Laser Displacement Sensor
Industry: Electrical/Electronics
Task: Measurement

Problem

We would like to detect deflections of a motor axis for a quality management of the motor. A high-precision measurement is hard with equivalent products of other companies because a sensing point has a mirror surface.

Solution

HL-C108B-BK　(x 2 units)
HL-C1C-M
HL-C1DP-E

Benefit

Measurement of deflections of an axis with hold function
Using peak hold function allows you to get data of the maximum or minimum amount of deflections. In addition, it is possible to measure a width of deflection by using “peak-to-peak mode.”

A mirror surface can be measured as well
We have a specular-reflective type head, which is very suitable for measuring a mirror surface and transparent object. Using a specular-reflective type head allows detection of objects, such as glasses and mirrors, that cannot be detected with a diffuse-reflective type.

Problem

We would like to control a length of an overlapped part in the laminating process of black rubber which is a material for tires. In addition, we would like to control dislocation by checking a thickness at two places on the right and left side. Rolling speed of a material is too fast for other companies’ sensors to get precise data. Since the material is black rubber, the amount of reflective light is little, which can cause an error.

Solution

HL-C108B-BK
HL-C1C-M
HL-C1DP-E

Benefit

Possible to response high speed of rolling objects
With the fastest sampling rate in the industry of 100us, the sensors can deal with high-speed rolling objects. The programmed data can raise its precision by increasing average cycles

Analog output for two heads
Since two sensor heads connected to one controller individually output analog current and voltage, it is possible to check states of two places. In addition, a computation function allows a calculation of a gap between two places, and you can check dislocation.

Data management is possible with a special software HL-C1AiM
Being equipped with RS-232C communication function, data management is possible with external equipment by communication . It is possible to analyze programmed data and check waveform on a screen by using HL-C1AiM

Problem

In a bead producing process at a tire factory, a sensor measures a size after wires being adhered to rubber and detects a lump of rubber or adhesive failure. With conventional sensors, it was hard to detect failure on a fast production line. In addition, it takes some time to change setting data of sensors at changeovers.

Solution

HL-T1010A
HL-AC1

Benefit

High-precision detection is possible
This sensor even detects fine changes of the amount of light; therefore, it can judge small changes of diameters. The sampling rate is 143us, which is fast. It is possible to detect failure even when objects pass fast

Automatic teaching function is equipped
Automatic teaching function is equipped, which allows you to set threshold value while objects are flowing. It is easy to set precise threshold value. Therefore, changeovers can be done very easily when objects change

Judgement function of fine or failure is equipped
Three outputs of HI-GO-LO is possible by setting upper and lower threshold value. By using it, the sensor can judge failure due to a lump of rubber as HI, non-defective as GO, and failure due to lack of adhesive as LO. This allows a quality management.

Problem

Sensors measure thickness of a clutch plate by measuring a distance between both ends and objects and calculating that result. However, with equivalent products of other companies, two sensors and controllers are needed in addition to a digital panel for calculation, which costs a lot.

Solution

HL-C108B-BK　(x 2 units)
HL-C1C-M
HL-C1DP-E

Benefit

Saving a lot of cost
With HL-C1 series, you can connect two heads to one controller; therefore, you can save a lot of cost compared to equivalent products of other companies in case you need several units for measuring thickness.

Computation function is equipped.
This sensor is very suitable for measurement of thickness or a gap because computation function is equipped in a special controller. It is very easy to set up the computation function for anyone since you just choose from several kinds of patterns already set up

Task: Suction/Vacuum Check

Problem

With products of other companies, it is not possible to detect black plastic mixed with quartz

Solution

Using of Ultrahigh-speed laser displacement sensor
HL-C108B-BK- Sensor Head
HL-C1C-M- Controller
HL-C1DP-E- Console

Benefit

Stable detection for black objects
Possible to detect black objects with little amount of reflective light by a linear image sensor type.

We cut slight noise, and stable detection for eccentricity measurement is possible
The noise by quartz that prevents proper measurement on eccentricity was cut by low-pass filter function, which makes stable measurement possible

Ultrahigh-speed sampling rate
With the fastest sampling rate in the class of 100us, higher-precision detection has become possible
