Hello all...
Just received the following
NPN DC6-36V Proximity Sensors, and im
waiting for the following
router to be delivered (so i can not test the switchs with the unit).
Right now im playing with the switchs using a bench power supply and they are working with 5v IN but when they are triggered, they only drop to 0.633v, not 0 volts, will this be a problem ?
Testing now with 12v (from bench power supply) to 5v voltage regulator.
Powering switchs with (brown wire) 4.978v from L7805 regulator
Not triggered, output (black wire) = 4.973
Triggered output (black wire) = 0.633
Secondary question(s) :-)
1) Would it make sence to use an exturnal power source (a "wall wart") hooked to a
5v voltage regulater, since the switchs are working at 5v ?
Knowing nothing about the control box (BOB) which comes with this router (aside from its an import), im trying to plan ahead so i have as little problems down the road.
2) Alittle electronic nieveness here...
I plan on using 6 switch, two for each axis.
Again, not knowing what the BOB with this router can do, would it make sence to wire three switchs in series (one per axis for the limits) and the other three by themselves for home (through reading on this board, thats seams pretty commen) to use less I/O pins ?
But... while testing two switchs in series:
5v power to (switch one) brown, then (switch one) black to (switch two) brown, there is a 2.5 voltage drop (so im gonna assume these switchs have some kind of resistors in them).
2a) So with that said, if i wanted to wire those three in "series" (more so, wire them so they only take up/use a single I/O pin on the BOB) could i run three to a relay (with resistors) and then have the relay hooked to a single pin (passing 5v through relay, then when one of the switchs triggers it will kill the power to the relay coil) ?
Thanks for any guidence.
