Fiber Optic Emergency Stops for Harsh Environment Applications

Fiber optic emergency stops provide immunity to EMI, RFI, and lightning; are inherently safe; and can operate at extremely long distances up to 10 kilometers. This whitepaper discusses how e-stops work, the standards that govern them, and how fiber optic e-stops outperform electromechanical estops in hazardous locations as well as other challenging industrial and medical operating environments. Also the FO E-Stop Controller/Remote Relay can be used to extend the reach of existing electromechanical e-stops or other switch-based sensors (level sensors, security, etc.).
