Re: SB72 + Photoelectric Sensor

Simply connect the supply to the device as per the specifications, 12-24V as shown in the drawing on page 6 of the data sheet. Connect GND to the GND of your Netburner and the output to your GPIO pin. Connector a resistor from the GPIO pin to +3.3V and it will work. Something like 4K7 or 10K will b...

Re: SB72 + Photoelectric Sensor

Connector a resistor from the GPIO pin to +3.3V and it will work. Any thoughts on what I could use as the 3.3V power source here? I'm supplying 5v to the SB72 board, would there be some point on the board that I could assume has a regulated 3.3V power source? Or would it be better to set up a separ...

Re: SB72 + Photoelectric Sensor

Hi Dave, thanks for your comments- is there a pin or something on the SB72 that I can use for the +3.3V?

Cheers, Chris

Re: SB72 + Photoelectric Sensor

Thanks all for your input so far! I now have a photo eye sitting on my desk, it is an Omron e3z-t61, which I believe will switch to ground: http://www.omron247.com/doc/pdfcatal.nsf/27EA3F3E915E668386256F6300610AC1/$FILE/D04E3Z1204.pdf To set the IO signal, could I draw 5v from the same power supply ...

SB72 + Photoelectric Sensor

I'm very new to all of this, and I was wondering if I could get some information about the best way to connect a photo eye to an SB72 board. I see that there are 4 available GPIO pins - what would be involved in using these? Is there a better way? Any help or guidance would be massively appreciated!
