Zoom Industrial Linear Actuator 4" Inch Stroke 330 Pound Max Lift DC 12v/24v Position Feedback Weather Resistant

Using twp of these to position some mirrors to reflect the sun to a solar collector. Tried to very the speed of the actuator, using pulse with modulation (PWM), that worked OK, but the position feed back, from the actuator, drifted when ever I drove the motor with PWM. If I drove the motor with a steady voltage, the position pulses did better, but still would drift depending on how often the motor would change directions. I used these outside, and yes I know they were not rated for wet areas. After about a year, some internals of one of the motors got corroded, and I took it apart, to see how it was constructed. It was constructed very well and also found, out how the drive limits worked

This is a very nice actuator, either 12 or 24dc I hooked mine up to a 24vdc supply. I am using it to lift a mattress with under-bed storage in my travel trailor. Surprise at how quick it lifts. Would have given it 5 stars but one clevis pin and two cotter pins were missing, which left me scrambling to find substitutions. Sorry but no excuse for missing parts just lack of care.

Item was poorly packed. Gromet where wires go into body is broken. Thin rope gasket around body has gaps. Would be better if an actual gasket was used.Otherwise actuator works OK.

used it to automate my chicken coop door... works great... probably overkill

Haven’t utilized it in the intended application but it appears to be exactly as described and look forward to see it in action.

this worked so well for what i needed it for thanks i would buy moere

PRICED RIGHT

Not heavy duty
