For sensors without built-in timer functions, operation follows the NORM mode shown with multifunction time delay models. 2. T1, T2 and T denote set time, variable within 0.1 to 5 second range. 3. For multifunction time delay models (part numbers ending in “T”), the ONand OFF-delay time settings will be the same. 4. For ON- and OFF-delay models (part numbers ending in “D”), T1 and T2 are independently variable. 5. O.S.D.: one shot delay 5 E3A2 E3A2 Engineering Data Through-Beam Type Retroreflective Type Diffuse Reflective Type Excess gain ratio Excess gain ratio Excess gain ratio ■ EXCESS GAIN RATIO Distance [m (ft)] ■ LIGHT SOURCE/RECEIVER SETTING RANGE Distance [m (ft)] Distance [cm (in)] ■ REFLECTOR SETTING RANGE Retroreflective Type Distance Y [cm (in)] Distance Y [mm (in)] Through-Beam Type Distance X [m (ft)] ■ OPERATING RANGE ■ DETECTING DISTANCE VS.
