The Contactless Mechanisms - Accuracy Without Wear


P-Q Controls' patented inductively coupled system used in multi-axis and level attitude sensors eliminates the wiping contacts of potentiometric devices and minimizes the number of moving parts. For certain single-axis and multi-axis joysticks and switched output controls, P-Q uses a design based on the latest Hall Effect technologies. Contactless devices, whether optical, inductive or Hall effect based, will not wear out - a major advantage over mechanical switches.

I'm new to electro-hydraulics. What else do I need to know to set up a system?


As a general rule, each proportional valve is a single axis of control (e.g., Forward/Reverse is one axis, Left/Right is one axis, and Boom Up/Down is one axis), which in turn requires its own driver and single axis joystick/control. A multi axis joystick may be used to control multiple valves with one hand.

The New Generation of Technology in Hall Effect


P-Q Controls began research and development in Hall Effect technology in the mid 1980's. What this means, is for the past 30 years, P-Q Controls has invested ample time and research into improving and perfecting this technology. When you buy from P-Q Controls, you can be sure that our products are field proven for long-term outdoor use under virtually any environmental condition.

Hall Effect Technology has grown to be the industy preference in contactless proportional control, and P-Q Controls is right there with you to provide the latest advances in this technology. This simple design exploits the characteristics of electromagnetic fields through the change in position of a small magnet in reference to an electrical current flowing through a conductive material. The result is a precise voltage output that is proportional to the position of the magnet, which is directly dictated by movement of a joystick.

Always staying one step ahead of the competition - that's the secret of our success. Our people are known throughout the industry as experts in programmable control design.
