I'd love some input on how to create a sensor that will automatically actuate a cutter for my SPP machine. I have DC input SSRs, two potent 120VAC solenoids to provide the muscle.
Basic option 1: SPP coil contacts a leaf spring, completes 12VDC circuit. SSR actuates, solenoid closes, cut. SPP falls, opens circuit which resets. Would a MOSFET or transistor or maybe added capacitance help with potential hysteresis or chattering?
Option 2: Photodiode, phototransistor. Again, hysteresis or chattering makes me nervous.
Hall effect wont work with stainless. An inductive proximity sensor?
I KNOW there are smart guys out there who could make short work of this. I understand schematics and general basic electronics. Thanks!
