Recommandations for a specific distance sensor?
Recommandations for a specific distance sensor?
(OP)
Hi,
I was wondering if somebody knew a good quality/price boolean sensor (2 outputs, on/off) that is "pot" adjustable in terms of distance.
For example, if I want to know if something is at the right place or not: The sensors' switch is closed if distance == 3,50 meters and the sensors' switch is open if distance !== 3,50 meters.
That would be in an ideal world but in the real world it should be something like: closed if 3,45m <= distance >= 3,55m and open if distance == anything else. (It doesn't need to be in the metric realm).
I found some of those sensors, but I would like to know what you, engineer brothers, know about those kind of sensors.

But I just want to know if someone has some feedback to give about those kind of sensors.

What is the object you're sensing? Some surfaces are easier to deal with than others.

Teachable just push the button of the distance that is needed to check, it learns this distance and configure for an output.
I am sure if you called your sick rep he would be happy to get you the part number. It has been years ago, I am sure its gotten better quality and more features and cheaper.

RE: Recommandations for a specific distance sensor?
First thank you all for youre replies.
Indeed I should have been more specific about what I want to sense, where and how.
I have to sense a wagon full of "muck" (dynamited rock) on a railway so that it unloads by itself at the right place. Of course it is made of metal (yellow paint). And this railway is situated more than a kilometer below the surface in a gold mine. The temperature average is 22 celsius so that wont be a problem.
It also has to be tough and easily cleanable.
I have heard about those teachable push buttons. If I have understood correctly, I think if we push that button the sensor will remember the current distance and will have the ouput that I want only at that distance. Right?
I think this is the best way to solve my problem.
I also have to find a good/tough beam break switch so that I know exactly the position of that mine wagon.
Any suggestions?

And I am pretty sure I am gonna find what I am searching for.

You still didn't state the distance. But it looks like you want something fairly far, I would do that with a Sick DME3000 distance measuring unit. It can go up to 10m in proximity mode (no reflector).

Erwin: "Nein, I'M Sick, you are ill!"
Patient: "No, I'm Franz, but you are sick? I'm going elsewhere, I'm already sick enough..."
