Is the 24’’ Stroke, 22lb Force, High Speed Linear Actuator
Product Code : RB-Fra-199
Fit for a sliding patio door? If so, what wificontroler and switch do you recommend?
TherE is another 24 in actuator fra-18 is this fast enough to open a door?
Also, what actuator would open a regular 32 in. Door. How long (Stroke) does it have to be?
Thank you in advance

Q1) {…} Fit for a sliding patio door? If so, what wifi controler and switch do you recommend?
Not too many people have automated sliding patio doors. Best to put it on the inside so it’s not exposed to the outside environment. It should work, though you might need to find the best spot to install it - either at the very bottom, middle or top, since there is a leverage effect and when putting, you want the door to stay horizontal. Since it’s a standard DC actuator, you need to send a signal via WiFi to either a DPDT relay or a DC motor controller. If wired correctly, two single relays might work:
We don’t offer many DC motor controllers with built-in WiFi, so you’d need to put two products together - a DC motor controller capable for 5A or more, and the WiFi module.
Q2) There is another 24 in actuator fra-18 is this fast enough to open a door?
Opening a door is less about the speed than it is about the force needed. RB-Fra-199 seems to be the best of both speed and force.
Q3) Also, what actuator would open a regular 32 in. Door. How long (Stroke) does it have to be?
By “regular” door, do you mean sliding or hinged?
Thank you for comments and info. By regular 32” door I mean a door with hinges. Which actuator do you recommend, any particular brakets and Which dpdt swicht would fit?
Also for the recommended WiFi relay I understand that you recommend a 5 volt because robotshop doesn’t have 12 volt models in its catalog. Correct?
Thank you

Q1) Which actuator do you recommend, any particular brackets and Which dpdt switch would fit?
A1) (Answer added after initial post) It depends on how the actuator is mounted. The maximum stroke will need to be calculated, along with the force needed. Most RB-Fra actuators on our site have corresponding mounting brackets, so if you can provide a drawing of how you’d like to mount it, we might be able to help further. The DPDT switch would correspond to the actuator chosen.
Q2) Also for the recommended WiFi relay I understand that you recommend a 5 volt because robotshop doesn’t have 12 volt models in its catalog. Correct?
A2) Normally there are two voltages - the input voltage to cause the relay to change its state, and the voltage range which the relay can handle. Normally relays can handle quite a large voltage range (check to be sure), but the switching voltage tends to be 3.3V or 5V.

According to their manual (page 2), the rated load is 5A at 24VDC. Double-check to be sure…
Regarding the hinged door, the force needed as well as the stroke depends on where and how it’s mounted. If it’s mounted at an angle, the torque changes, and both the min / max torque and stroke need to be calculated using physics and math.
Maybe you can recommend companies which help to install exterior doors. Recently I have moved and want to change all doors because they let in a lot of heat. Thanks in advance
