Hi all,

A while ago Liam kindly gave me this:

I think it is a Linear Actuator, however I can't find any data sheets for it. (Wiring etc.)

Any help with this would be great!

Using the model number, I found it on Aliexpress

https://www.aliexpress.com/item/32596077754.html

It doesn't appear to be a linear actuator, but is used as a position detection device. According to the seller it's applications include: injection molding machines, die-casting machine, blowing machine, shoe machine, printing presses, woodworking machinery, cable machinery, linear displacement equipment, industrial automation equipment.

Hi again,

I think that the red wire is positive but I can't see negative!

Do you have any idea what wire might be negative?

Thanks again,

Thanks Ben, that's great!

Hi again,

I have made some progress, I have an Arduino Uno and have wired the Red Wire to Ground (Numbered 1 in Datasheet), Blue Wire to 5V (Numbered 3 in Datasheet), White Wire to Digital Pin 8, and have not wired up the Green and Yellow wire (Not numbered in data sheet but is a different shaped pin than the rest). Is this wiring correct?

I ran this code:

Code: Select all

int readPin = 8;
int Status1;

void setup() {
Serial.begin (9600);
pinMode(readPin, INPUT);    //Set button pin as an input

}

void loop() {
 Status1 = digitalRead(readPin);
 Serial.print (Status1);
 delay (1000);

}

And the Serial Monitor looks like this:
"00011000011111110001111100000000000001111111110110110000000000000"

"1" = Extended.
"0" = Not Extended

So that's correct.

Now how do I control this thing! do I have to wire up the Green and Yellow wire (differently shaped Pin from the rest)? If I do where do I wire it to?

Any help would be amazing!

.....or Ben10 did I misunderstand you and you were saying that I can't using code, move the piece of metal that comes out the bottom I can push up and down? Can it only measure distance?

Really sorry if I did misunderstand you!

Thanks!

Look at the symbol on the side - what does it look like?

Youre doing well Zeb!

Hi Mr Liam,

The symbol is 3 lines like this "-" the top one is the smallest followed by the middle one and the the bottom one is the longest, then attached to the bottom line is short a vertical line.

I can upload an image soon if needed!

What does this symbol mean?

Thanks very much!

...... Is it a ground symbol?

Here is a picture I drew of the symbol!
