Man, Its just one thing after another with this project. I think I got myself in over my head but I cant back down now. The robot arm alert system Im working on was designed to disable the photo sensor when the door is open. It has a laser and for operational and safety reasons the laser needs to shut off when the door is opened. The Robot already has a door safety switch that sends a signal to the robot so the robot will not move unless the door is closed.
I assumed the 2nd set of contacts on the Omron safety switch was another set of N.O. terminals. After looking it up I see it is a set of N.C. terminals. And of course every single safety switch I see has more than one set of N.C. terminals but NONE have more than one set of N.O. terminals. This is getting aggravating.
Can anyone help? I dont want to have to put a second safety switch on it and I looked in a 2 wire sink/source inductive switch but they say the load current is 0-100Ma. Im not sure if that is how much current it draws or if its how much current it can handle . I probably got this confused. But if I have this sensor in front of a device that draws up to 250Ma so that the device only receives voltage when the switch is closed, can this switch handle the 250Ma draw from the device when the switch load current is rated at 0-100Ma?
Here is the switch
