thanks for the response. This was a project for fun only. A verry low cost engraver, fast an cheap build (LD ~ 2€, Driver LM358 based, arduino clone 2€).
i use a big and a fast CNC Engraver with a ~2W Laser for Wood Engraving (Pens and small wooden cans).
China seller offers CDR-based...
i know .. but the connection is ok - and this circuit is reverse polarity protected (D2) ;-)
the RS232 connection will not be established. i have tried this with a FT232RL (works on my other Ophir Head). No Communication .. only a unaccurate analog output
measurement and phone with ophir support helps me a little (unofficially :-D)
the only thing that is the same on all custom sensors with 6pin molex (95%)
1 - custom
2 - GND
3 - Vin (0.5 means that the sensor has clibrated 0.5V/1W - for 20W we need 10V + 2V => 12V, for 2W it is working with...
ophir tells me .. the sensor with this serial number is a customer builded sensor (OEM). It is not a standard sensor. The RS232 protocol is unknown (no documentated ophir std protocol).
No Information, No datasheet, No support (only for the first customer, but not me)
With a own (std-)...
i have bought a used ophir 20C-UAS, but the sensor does not work.
Its a 6-pin Molex connected module. I have contacted Ophir and they tells me, this is a NDA Sensor .. i cant get any informations about the interface or Analog-Output.
i think .. this Sensor is damaged, but the...
can anybody help ?
What is the rigth datasheet
SLD3237VF Datasheet (Page 2/2) | DatasheetLib.com
the same layout and the same text, but different current and voltage
today, my LG Disc Rewriter has crashed one of my discs. Now .. no detect any CD or a DVD.
I never used as writer, so i think, tha blue LD is unused.
What laserdiode type is this ...Anybody knows ?
