Featuring EZ-Beam technology to provide reliable sensing without the need for adjustments; "T" style plastic housing with 30 MM threaded lens mount; Completely epoxy-encapsulated barrel-mount sensors operate on dc supply voltage and withstand harsh sensing environments; Advanced diagnostics to warn of marginal sensing conditions or output overload; Available in opposed, retroreflective, diffuse and fixed-field modes; Innovative dual-indicator system takes the guesswork out of sensor performance monitoring; 2 green and yellow LED indicators: green on steady - power to sensor is on, yellow on steady - sensor sees light, yellow flashing - excess gain marginal (1 - 1.5x) in light condition |
