CURRENT REQUIREMENTS

? 85mA (exclusive of load)

OUTPUT TRANSISTORS

? (1) NPN and (1) PNP Output transistor:

? NPN: Sink up to 150mA
? PNP: Source up to 150mA
? Momentary short circuit protected
? Outputs protected from pulsing during power up
? Light/dark switch determines Output Status:
    Light = Light ON operate
    Dark = Dark ON operate

RESPONSE TIME

? Minimum duration of input event
? Light state response = 50 microseconds
? Dark state response = 140 microseconds
? Leading edge Variation less than 20 microseconds

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. Blue = 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 (EDR?) 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,EDR? adjustment has been set
? FULLY LIT: Operating near saturation
? OFF: Operating near maximum sensing range
? CONTRAST INDICATOR – Displays scaled reading of sensor's response to   contrasting light levels (light vs. dark) on a ten bar LED display

AMBIENT TEMPERATURE

? -40°C to 70°C (-40°F to 158°F)

RUGGED CONSTRUCTION

? Chemical resistant, high impact   polycarbonate housing
? Waterproof, NEMA 4X, 6P and IP67 enclosure ratings
? Epoxy encapsulated for mechanical strength
