| Pounds Per Square Inch |
| A measurement of pressure in the American system. By way of comparison, the weight of the atmosphere (one atmosphere) is 14.7 pounds per square inch, at sea level. It is used to express pressure in both pneumatic and hydraulic-powered systems. In the IS Metric system, pressure is measured in Bars. To covert PSI to Bars, take the PSI figure and multiply it by 0.0689476. |

| Proximity Sensor |
| An LED-equipped device for sensing end-of-stroke on cylinder slides. Proximity sensors supply either a sourcing signal or a sinking signal to a device such as a programmable logic controller. |
