Q3X Laser Contrast Sensor
Quick Start Guide
™
Laser Expert diffuse sensor with bipolar (1 PNP & 1 NPN) output. Patent pending.
This guide is designed to help you set up and install the Q3X Sensor. For complete informaꢀon on programming, performance,

WARNING: Not To Be Used for Personnel Protecꢀon
Never use this device as a sensing device for personnel protecꢀon. Doing so could lead to serious injury or death.
This device does not include the self-checking redundant circuitry necessary to allow its use in personnel safety
applicaꢀons. A sensor failure or malfuncꢀon can cause either an energized or de-energized sensor output
condiꢀon.

Figure 2. Display in Run Mode
In Run mode, the 3-digit, 7-segment display provides real ꢀme informaꢀon about signal strength for all models and target posiꢀon for
models with a fixed background suppression distance. The numeric value of 0 to 990 represent the amount of the received light divided
by the threshold, and represents the excess gain of the sensing event expressed as a percentage of the switch point. This value is called
normalized signal strength (NSS). A NSS display range of 999 indicates a saturated received light signal, meaning that low contrast
detecꢀon is not possible.
In single threshold teach modes (Two-Point Staꢀc, Dynamic, Light Set, or Dark Set), the output switches at a displayed value of 100
(excess gain of 1.0).
For models with a specified background suppression distance,
background suppression distance and is being suppressed. In Light Operate mode, the output switches off when
background suppression models, the sensor's output state when displaying can be controlled using the
indicates that a target is present at a distance beyond the
displays. For the
menu. By default,
the sensor treats a target in the background as a dark signal and honors the LO/DO selecꢀon.
A displayed value of indicates no light received or a loss of signal.
In Window Set teach mode, the value 100 represents the taught signal strength. The displayed value is the percentage of the received
light divided by the taught signal strength. The output switches at displayed values above and below 100 as determined by the user-
selected window offset percentage.
