Linear Potentiometers
Tol-O-Matic Absolute Position Feedback


What rhymes with "gaggle?" Certainly not APF! Why put up with a flock of switches, potentiometers and other such stuff? Why expose these devices to the environment, subject to contamination, wear and what not? Is this any way to treat the Christmas goose?

Add-ons are afterthoughts. Is that any way to treat your critical application?


Quick: who said "Form follows function?"
Answer: Louis Sullivan (1856-1924). Actually, Louis said this, "Form ever follows function." Now that is some good advice, for it means that the outward design and form adheres to the function beneath the visible form. Translation: the underlying design and its visible form work together. (Study an egg and ask a chicken; you'll get a nod of agreement.)

Now study the APF option from Tol-O-Matic, available on pneumatic and electric rodless actuators. Beautiful, isn't it? Sleek, enclosed, no wear, accurate and repeatable to handle most applications.

Old Louis would have been proud!



O.K., it's Monday morning and the 2nd shift from Friday left the tool right inside the metal part to be formed (or welded or fixtured…) Now what? Hit the power and wait and see what crashes? What was that sound? Sounded like a big bird smacked the side of that machine!

What is the point of work? This is not a philosophical question, but a very real and legitimate query. With Tol-O-Matic's APF option, you know where the work is at all times. The permanent magnet mounted in the load carrier induces an elastic deformation of the transducer, forming a mechanical wave.

Moving at 9,285 feet per second, this mechanical wave is intercepted by the signal converter. Since the travel time is directly proportional to the distance between the carrier magnet and signal converter, you know where the work is. Ingenious, ain't it? Works every time.



Linear potentiometers: gone.

Incremental linear encoders: gone.

Cable extension transducers ("string pots"): gone.

Linear Variable Differential Transformers (LVDT): gone.
APF: here to stay.


Gaggle time. Your goose is cooked!

Form and function from Tol-O-Matic.
Happy Holidays!


There are 11 differences between the cartoons: 1. One dog cut out reads "Crow Time!" instead of "Chow Time!"; 2. Full waste bin vs empty;
3. Guy is carring a tool box instead of an employee reward; 4. Unhappy face vs happy face; 5. Wrench in pocket vs pen;
6. Box of switches on machine vs none; 7. Run homing routine at power-up note vs none;
8. Work order change routine directions vsselect work routine button; 9. Numerous switch cords on actuators vs none;
10. Running routine spelled out "Chew Time!" instead of "Chow Time!"; 11. Mounting, wiring and alignment of external position feedback devices.
