HYSTERESIS |
•Less than 400 millivolts for maximum sensitivity and resolution |
LED LIGHT SOURCE |
•Pulse modulation rate 45 KHZ •Choice of color: A. Infrared = 880nm B. Red = 660nm C. White = Broadband Color Spectrum D. BIue = 480nm |
LIGHT IMMUNITY |
•Responds to sensor's pulsed modulated light source •Immune to most ambient light |
OFFSET/EDR® ADJUSTMENT |
•Sets initial level on CONTRAST INDICATOR in relation to mid-scale switch point of 5 – functions as sensitivity adjustment •Controls Enhanced Dynamic Range circuit (EDRTM) which functions to avoid saturation |
INDICATORS |
OUTPUT INDICATOR | RED LED illuminates and the NPN or PNP outputs switch to the opposite state when returned light level exceeds “5” on the CONTRAST INDICATOR |
EDR™ INDICATOR | Intensity of GREEN LED provides indication of where in the dynamic operating range the offset, EDRTM adjustment has been set |
FULLY LlT | Operating near saturation |
OFF | Operating near maximum sensing range |
CONTRAST INDICATOR | Displays scaled reading of sensor's response to contrasting light levels (light s. dark) on a 10 bar LED display |
