[QUOTE="ArloG, post: 1161788, member: 418555"] Not really a good idea but you could try it. I'm guessing that if it was workable, it would have already been done. And if you think about it. The hall sensor needs it's own Vcc to operate. Using a common power source would 'drag' it down when activated. Believe me. And others. And think why a power tap into the v-box was necessary in the first place. The sensor needs it's own dedicated power rail. Period. You are free to see if you can wire in a reed switch in place of the hall unit. And use only 2 wires. But still 2 wires out to the actuator invites motor noise. You need that shield. Shield and 2 wires or shield and 3 wires. It's how it's done. And has been. For like....ever. For me. I use an ASC-1 actuator control. It also is meant for reed switches. There were add-on relays that allowed usage with hall/optical encoders. But. Still. At [I]least [/I]3 wires are needed out to the sensor. I made my own with a miniature Crydom SSR. The hall sensor gets 5 volts from the terminal strip. Normally used to power a polorotor if one is used. The hall sends back 5 volts through the SSR and lights the internal optocoupler. The SSR output acts as a switch closure and triggers the ASC-1 internal optocoupler. Hey man. It ain't my first day in industrial sensor interfacing and positional control. Actually now thinking about it. In an attempt to get a nice square wave trigger into the ASC-1. And to extinguish it's own internal opto LED a bit quicker. I added a series resistor from the SSR out to the sensor in terminals. Worked slick! Nice, fast, and pretty square pulses. And at 20ppr of the slotted optical encoder disc I made. Very high count resolution with a 36" actuator that tracks from 127W out to at least 40.5W. [/QUOTE]
