Photoelectric Sensor Selection Guide
Online Learning Contact a Banner Engineer About Your Application

Overview

High performance mid-range adjustable-field foreground suppression sensor complementing the QS18AF short-range and Q60LAF long-range series sensor.

  • 128 element photo receiver for superior performance on varying colors and textures
  • Sensing range in midsize QS30 housing – 400 mm (6% Black Card)
  • Foreground suppression for reliable detection with a fixed background is present and object color or shape varies
  • Linear multi-turn screw adjustment for cutoff distance
  • Enhanced immunity to fluorescent lights
  • Crosstalk immunity allows two sensors to be used in close proximity
  • Tough ABS housing is rated IEC IP67; NEMA 6
  • Bipolar discrete outputs, PNP and NPN
  • Models available with 2m or 9 m (6.5’ or 30’) cable or integral metal quick-disconnect; or 150mm (6”) pigtail
  • Mounting versatility via popular 30 mm threaded barrel or side mount
  • Large, bright output indicator

Product Specifications

RangeAdjustable Cutoff Range: 50 to 400 mm

AdjustmentsFour-turn adjustment screw sets cutoff distance between min. and

max. positions, clutched at both ends of travel
Indicators2 Indicator LEDs on sensor top:

• Green ON steady: Power ON

• Yellow ON steady: Light sensed

(excess gain > 1.5x)

• Yellow flashing: Marginal sensing condition (excess gain < 1.5x)

2 Indicator LEDs on sensor back:

• Small Blue/Red End-of-travel (EOT) LED

• Large Yellow Output LED
