Technical Features

Model Specific

Adjustment Type:

  • Push Button

Connection Type:

  • Cabled, 20ft

Housing Type:

  • Rectangular
Family Specific

Supply Voltage:

  • 10 to 30 VDC
  • Polarity Protected

Current Requirements:

  • 50mA (exclusive of load)

Output Transistors:

  • (1) NPN and (1) PNP sensor output transistor:
    NPN: Sink up to 150mA
    PNP: Source up to 150mA
  • Continuous short-circuit protection
  • Outputs protected from pulsing during power up

Remote AUTOSET Input

  • Opto-isolated momentary sinking input (10mA)

Response Time:

  • Light State = 100 microseconds
  • Dark State = 100 microseconds

LED Light Source:

  • Red 660nm
  • Pulse modulated

Push Button Control:

  • "One-Touch" AUTOSET pushbutton setup
  • Tweak adjustments with "up" or "down" buttons
  • LST (Light State Tracking) Enable/Disable
  • Light "ON"/Dark "ON" Selection

Range:

  • Optimum from 6in. to 8ft. (15.24cm to 2.4m) distance to the AR6151 reflector

Hysteresis:

  • Two bars as displayed on Contrast Indicator
    Light State Switch = 5
    Dark State Switch = 3

Light Immunity:

  • Responds to sensor's pulse-modulated light source, resulting in high immunity to most ambient light, including high intensity strobes

Diagnostic Indicators:

  • Contrast Indicator - Display scaled reading of sensor's response to contrasting light levels (light vs. dark) on an 8-bar LED display
  • Red LED Indicator - LOCK
  • Green LED Indicator - LST (Light State Tracking)
  • Red LED Indicator - OUTPUT

NOTE: IF Output LED flashes, a short circuit condition exists

Ambient Temperature:

  • -40°C to 70° (-40°F to 158°F)

Rugged Construction:

  • Chemical resistant, high-impact polycarbonate housing
  • Waterproof ratings: NEMA 4, IP66

UL CertifiedCE Certified
