content: Hi All,This is my first post as I am normally able to find the answer out there.I have gone out on an expensive limb and purchased a SICK laser for a project I'm building.I am using an Arduino Due with this laser that works with RS422 and I'm using a converter to get it to RS232Here is a link to the information sheethttps://www.dropbox.com/s/s0lea5mcr8uta1r/SENSICK_OD_Value__2013-10-23__07-29-15.pdfThe electrical connection is the OD2-xxxxxxAx this is the RS422 model.I am connecting L+ (pin 1) to 12 volts and M (pin 3) to 0 volts (GROUND from what I understand)The laser does not do anything, the LEDs on it don't turn on.I know there isn't a lot of information but if anyone has an idea please helpThanks in advance.

content: Sounds good in German. I have an ancient optoswitch made by them. Uses all Siemens IC's inside, and has a eurocard sized controller in addition to the sensor head. At 40 years old the4 thing still works perfectly, though you can replace it these days with one half the size of the head unit only and get a unit with multiple wavelength sensing, false object rejection and all other bells and whistles which does it all and then some.

I was working on a computer that was a few feet away from a "Do not cross" line and I had to get down on my knees to work on it and I did something that caused me to have to extend my leg to steady myself and it went about an inch over the line and a few million dollars worth of equipment just froze in mid production and a red light started flashing.I excused myself for about 5 minutes until someone came over with a puzzled look and pressed the reset button. He never saw me.

content: Most common use in in lift doors as a safety barrier. Any object more than 5mm diameter placed in the sensing line keeps the door open. There are cheaper models for machinery guarding that detect 15mm objects.
