Abstract
A configurable operator panel that uses a tactile sensor with electrically conductive elastomer and appropriate electronics is disclosed herein. The device relies on a robust and inexpensive tactile sensor that senses the touch position (and may or may not sense touch pressure as well). The physical interface is easily configurable along with the electronics, which execute the desired function based on touch location and pressure. The configurable operator panel is designed to communicate with most industrial automation equipment, including but not limited to, motion control equipment, programmable logic controllers (PLC), personal computers, and can be made to control other types of machines requiring external analog or digital input.
