I have a question regarding the overall length of the linear actuator (P16-50-256-12-P) shown in the drawing.
1. First, could you please confirm the unit of measurement used in the drawing? Are the dimensions in inches or millimeters?
2. According to the drawing, the actuator body length is marked as 70, and the total length is described as stroke + 47. However, I plan to purchase the version with a 50 mm stroke, and based on the drawing proportions, the total length should be well over 100 mm, possibly closer to stroke + 147.
This raises the question: Is there a mistake in the drawing (e.g. should it say stroke + 147 instead of stroke + 47), or am I misunderstanding the reference points?
Could you please clarify what the actual overall length will be for the P16 model with a 50 mm stroke?
The electrical connector on the drawing picture shows the insulation of the wire has a diameter of close to “2.54”. There is no way the the wires are 2.54 inches thick, but they can easily be 0.1"(2.54mm) thick so the dimensions must be in mm.
I just opened the data sheet link on the part page and the removal of the drawing from its data sheet context created the units of measurement ambiguity. The first two data sheet pages make clear the dimensions are in mm.
I read this drawing as saying, if you buy a part with 50mm stroke then the distance between the mounting holes when fully extended = 50 + 47 = 97mm, when fully retracted the distance between mounting holes = 47mm. That as you correctly point out seems impossible, since the body is 70mm. I agree that stroke + 147 would make sense but the only way I could know for sure is to have one in my hands.
The table on p1 of the datasheet clarifies the second point in question; the drawing shows the device in a retracted condition, and in that state the hole-to-hole length is 47mm in excess of the stated stroke length.
