The E3X-DAS fiber optic sensor from Omron Electronics LLC is suitable for high-speed materials handling, packaging and sorting; electronics packaging; and pharmaceutical applications. Power is automatically adjusted to the appropriate level. A dual display allows the user to change the set point while monitoring the incident level, facilitating sensor configuration. An auto power control circuit compensates for LED degradation and provides stability. Other capabilities include differential mode and counter and remote input functions. The sensor has a four-element LED and a function lock that prevents tampering.
