A Displacement sensor has never been so easy like CD4 H Simple buttons for operation w/// give simple display.

RS-232C

Low/High Filter installed inside

In addition to average setting, High/Low path professional filters are equpped Inside. Low path filter cuts noise, and high path filter will remarkable change of values neglecting slow change of surroundings.

1. Communication Function of CD4

Connecting the PC and CD4 allows following operations from the PC:

• Writing and reading out the setting value

■ Reading out the measurement value

■ Reading out the control output status

• Operating the control input

■ Date buffer function

2. Communication Specification

Simple Display

The self-contained amplifier CD4A-N(or P) has a simple color monitor than can show multiple data at same time. Data of distance from two sensor heads, calculations between heads, Bank No., etc.

Visible light intensity (Specular Type)

For exact and stable measuring you need to set the best light Intensity. You can monitor the status with the built-in display.

The underlined setting is the factory defaults of CD4.

Easy disconnection Convenient for wiring thanks to QD terminal.

Adjust the communication setting of PC and CD4 within the

range shown in the above table.

Set the CD4 setting at 14 .RS-232C tn the SET mode.

Linear Imaging sensor of high

100ms sampling is realized by adopting Linear Image Sensor with high condensed pixels.

Electronic Shutter

5 of independent comparator outputs are possible 2 heads be controled by single amplifier

Microcomputer of CD4 will autmatically control its shutter

depending on reflectivity of object.

This will lead the measument in the best light intensity

to mininize the error as less as possible.

(at AUTO Sensitivity Mode)

This is convenient for sorting depending on size of objects.

5 of independent comparator outputs are possible to set, and each output can set high/low limit.

Therefore it computes for the purpose of measuring thickness, width, etc.

Independent measurement between two heads are possible, too. Any head of different range of distance is possible to fit.

Conventional Displacement Sensor with dull response

Saturation level

Sensing element

High reflective material will give excessive intensity of light that may cause error of peak position.

Sensing element

Low reflective material like black

rubber will give too small enegy

back to the sensor.

Therefore measurement cannot be

stable.

CD4 series products, possible to work in short cycle of sampling.

Calculation formula

Bank selection input

IP67 sensorhead.


	A	Sensor Head A
	B	Sensor Head B
	A+B	Adding of A and B
	A-B	Gap between A and B
	-A-B	Reverse of A+B
	K-A-B	K = distance between sensors. Good for measuring thickness.
	K+A+B	K = Offset value
	K+A-B	K = Offset value
	K+A	Offset the sensor A. K = Offset value
	K+B	Offset the sensor B. K = Offset value


Bank No.	Bank 2 input	Bank 1 input	Bank 0 input
0	OFF	OFF	OFF
1	OFF	OFF	ON
2	OFF	ON	OFF
3	OFF	ON	ON
4	ON	OFF	OFF
5	ON	OFF	ON
6	ON	ON	OFF
7	ON	ON	ON

CD4 heads are washable at your production site.
