SEIWF1 - Mark II SMARTEYE with in-Line Connector
SUPPLY VOLTAGE • 12 to 24 VDC • Polarity Protected |
LIGHT IMMUNITY • Responds to sensor's pulsed modulated light source • Immune to most ambient light |
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 |
RUGGED CONSTRUCTION • Chemical resistant, high impact polycarbonate housing • Waterproof, NEMA 4X, 6P and IP67 enclosure ratings • Epoxy encapsulated for mechanical strength |
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 |
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 LlT: 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 |
RESPONSE TIME • Minimum duration of input event • Light state response = 50 microseconds • Dark state response = 140 microseconds • Leading edge Variation less than 20 microseconds |
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 |
HYSTERESIS • Less than 400 millivolts for maximum sensitivity and resolution |
AMBIENT TEMPERATURE • -40°C to 70°C (-40°F to 158°F) |
CURRENT REQUIREMENTS • 85mA (exclusive of load) |
