SUPPLY VOLTAGE
|
• 12 to 24VDC
• Polarity Protected
|
|
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
