Laser Head Height Sensor – Looking for a Beta Tester

This is "only" a sensor that transmits the distance value to the CNC System. The CNC System must be able to use it.

If you have any ideas how i can help, I would be grateful for your advice.

At the moment I have accepted that the frequency will be the best solution.

so I implemented freq. scale
0-10mm -->> 20kHz - 70kHz   (10kHz = colision )
( each of steps 0.05kHz = 0.01mm ).
It works exactly as it should.
of course is availabe analog output 0-10V and you can use the analog output or frequency (a square 50% duty signal and any voltage) depended what you need.

first test frequency output on my desk :

Also I noted that on some laser cutting solutions the capacitive BCL-AMP is being superceded by amplifiers with a 0-10 volt signal?

could you give an example / link ?
I was looking some time ago for such sensors but I found only one that did not meet my requirements.

This one says height sensor is Ethercat or +- 10v

Some of their  controller packages refer to a TTA interface but don't describe it anywhere

Having a more open spec rather than closed source will be much better anyway.

I would say a couple hundred KHz so pretty much any encoder interface could work.
Also better if its a square wave so it asks the least of the frequency/period counter.
An offset frequency is good also so you don't lose bandwidth near 0 frequency.

Hi PCW

   If in your opinion square signal 20kHz = 70kHz for 0-10mm distance ( 0.05kHz / 0.01mm resolution ) is good idea ?
And 10kHz for colision.

Yes, 20 to 70 KHz should be fine as it will work with general encoder/counter inputs
and always high enough frequency so the control bandwidth is not affected.
