Hey All,
I need help with RC circuit tuning.The Problem- I am using a Reed switch which detect an magnetic object passing just above it. One side of the switch is hooked to 24V supply from a controller and the other is grounded.When the waveform is observed on the oscilloscope(when the switch closes),the pulse width for the signal is found to be 3ms with an amplitude of 24V.But the controller has a scanning time of 50ms and only detects the signal if the signal is above 10V for 50ms.Now I need to design the RC circuit that can charge the capacitor in 3ms and remains above 10V for more than 50ms.Also I can't have a very small resistor since the reed switch has a max. current limit of 0.5A.
Can anyone help me with this.I have to do it using RC circuit only.
Thanks!!
