A good linear actuators buying guide for home projects has to answer six questions in the right order, because getting one wrong turns a weekend build into a returns queue. Force, stroke, feedback, voltage, control and connectors — settle those and the rest of the project is carpentry.

This guide walks through each decision using Progressive Automations parts as worked examples, since the company covers everything from micro actuators up to industrial units and publishes the specs you need to size a build. Whether you are lifting a TV out of a cabinet, tilting a solar panel or opening a chicken coop door on a timer, the process is the same.

What a linear actuator actually is

A linear actuator turns rotation into a straight push or pull. Inside is a small motor driving a screw, which extends and retracts a rod. That is it. What varies between models is how hard it pushes, how far it travels, whether it can report its own position, and how it is wired.

For home use the appeal is that it replaces a hinge, a gas strut and a lot of fiddling with something you can trigger from a switch, a remote or a phone. Progressive Automations positions itself around exactly this range, from smart workstations up to full industrial setups.

Step 1: force, and why you should overshoot

Force is the first filter and the one people get wrong. Weigh or estimate the load, then account for the fact that a load pushed at an angle demands more force than the same load lifted straight up. Buying a unit rated close to your calculated load leaves nothing for friction, binding or the day someone leans on it.

The spread available is wide. At the small end, the PA-MC3 micro linear actuators are built for tight installations, with reinforced plastic construction and built-in limit switches, in configurations up to 27 lbs. That is plenty for a hidden panel, a small hatch or a display mechanism. At the other extreme, the PA-HD3 heavy-duty actuator with feedback uses a stainless steel shaft with metal gears in an ACME screw design to push and pull up to 2,698 lbs and hold up to 3,372 lbs.

For most household projects you will land somewhere between those, and the sensible rule is to pick the next rating up from your estimate.

Step 2: stroke length and the space you actually have

Stroke is how far the rod extends. The trap is that a retracted actuator is always longer than its stroke, so a 12-inch stroke needs meaningfully more than 12 inches of clearance. Measure the closed length, not just the travel.

Mounting is the other half of this. Progressive Automations sells bracket sets matched to specific actuator models — the set for the PA-ST5, for instance, includes a bracket for each end plus the required pins, in steel with a salt spray treatment finish, and allows 180 degrees of rotation. Buying the matched bracket set at the same time as the actuator saves an entire evening of improvising with angle iron.

Step 3: do you need feedback?

Feedback means the actuator reports its position back to the controller. Without it, the actuator simply runs until it hits a limit switch or you release the button. With it, you can stop at a repeatable point, or keep two actuators moving together.

There are two common flavors. Potentiometer feedback is the simpler approach: the PA-01-POT builds it onto the compact PA-01 mini platform, with a stainless steel stroke rod and aluminum alloy housing, an IP65 rating, 12VDC and 24VDC options and a wide stroke range. Hall effect feedback is the more precise option and is what the heavy-duty PA-HD3 uses, which matters when you are synchronizing multiple units.

The honest answer for a first project: if you are moving one thing between fully open and fully closed, you do not need feedback. If two actuators have to lift a single flat surface without racking it, you do.

Step 4: voltage and the power supply

Most home-scale actuators run on 12VDC or 24VDC. Twelve volts is the default and pairs naturally with automotive and battery projects. Twenty-four volts draws less current for the same power, which helps on long cable runs.

Then size the supply to the current draw, not to the actuator count. Progressive Automations' range makes the ladder clear: the PS-13-12-67 accepts 100-240VAC input at 47-63Hz and outputs 12V through a 1x2-pin Molex Mini-Fit Jr connector, handling up to 12.5A in a 150W package. The PS-29-12-67 steps up to 29A through a 2-pin Hirose DF60 connector, and the PS-50-12-67 reaches 50A on a 4-pin Hirose DF60 for high-power control boxes. On the 24V side, the PS-15-24-67 outputs up to 14.5A.

All of those carry an IP67 rating, meaning they can withstand water submersion in harsh conditions while static, and include short circuit, overtemperature, overload and overvoltage protection. For any project living outdoors — a gate, a coop, a planter cover — that rating is the specification to check first. Our deeper dive into control boxes and power supplies covers how to pair them properly.

Step 5: how you will actually control it

A rocker switch is the simplest control and perfectly adequate for a single actuator. Beyond that, a control box does the switching, the synchronization and the remote handling for you.

The PA-CB41-2-12V24V is the high-current option for synchronizing two hall effect actuators, supporting both 12VDC and 24VDC systems with plug-and-play compatibility across the company's actuators, power supplies and wiring kits. It runs a self-learning pairing procedure so it works with a wide range of actuators in its supported range, and adds higher power output, longer duty cycles and faster wireless response than earlier boxes. If your project needs four actuators moving together, the PA-CB40-4-12V24V does the same job across four channels with an upgraded four-button remote and onboard setup.

For app-based control there is a Bluetooth route: the RT-BT1 dongle pairs with the FLTCON-3 control box using a dedicated 8-inch six-pin Molex Micro-Fit adapter. That is the path to take if the actuator needs to join the rest of your smart home setup rather than living on its own remote.

Step 6: connectors, the step that ruins weekends

Nothing derails a build faster than discovering the actuator plug does not match the control box socket. Progressive Automations effectively admits this by selling an entire category of adapters, and reading that list before you order is the cheapest insurance available.

Write down the exact connector names on both ends before you buy. It takes five minutes and saves a shipping cycle.
