Just purchased the RB-Dfr-49 sensor and have it working on the bench top. Would be better for my application if the internal trigger worked opposite what the current sensor does. That is to say would like the output to be low when there are no obstacles and high when there are obstacles. I have added an external transistor circuit to accomplish the conversion but this project is very cost sensitive. So if I can get a sensor that is internally wired in the desired scheme that would help. Do you carry a sensor made by the same company that would sell in approximately the same price range?
Unfortunately, the manufacturer does not have a sensor like the RB-Dfr-49 but with an an inverted output.
I’m guessing you’ve used the transistor to make a circuit like this? That’s probably the cheapest option.
Sorry to hear they don’t make anything like that. You are correct in your assumption we are using a transistor circuit to invert the output.
Thank you for all your help and have a great evening.
