Standard 2 m (6.5 ft) cable models are listed. To order the 9 m (30 ft) cable model, add suffix "W/30" to the cabled model number. For example,
QS18EN6FP W/30. Models with a QD connector require a mating cable.
To order a model with a 4-pin QD 150 mm (6") Euro-style pigtail, add suffix “Q5” (e.g., QS18EN6FPQ5).
To order a model with a 4-pin 150 mm (6") Pico-style pigtail, add suffix “Q” (e.g., QS18EN6FPQ).
To order a model with a 4-pin Integral Euro-style QD, add suffix “Q8” (e.g., QS18EN6FPQ8).
To order a model with a 4-pin Integral Pico-style QD, add suffix “Q7” (e.g., QS18EN6FPQ7).
WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. 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 applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

The QS18E Expert Sensors family of sensors provides high-performance sensing in
a compact package. The sensors feature a discrete output (NPN or PNP, depending
on model), two bright LEDs for easy status monitoring during configuration and
operation, multiple configuration options, remote configuration, and security
lockout options.

Output OFF ON OFF
Output ON ON ON

Output Short Circuit Flashing OFF
Sensor Configuration
Configure the sensor using any of five TEACH or Set options (by push button or the
remote wire) to define the sensing limits. Use a Setup procedure to enable a 30 ms
OFF-delay or to change the Light-/Dark-Operate setting (see QS18Expert Sensor
Setup). Sensing limit configuration options include:
Static TEACH: one switching threshold, determined by two taught
conditions
Dynamic (on-the-fly) TEACH: one switching threshold, determined by
multiple sampled conditions
Light Set and Dark Set: one switching threshold, offset from a single
sensing condition (the “dark” condition or the “light” condition; see Figure)
Window Set: a sensing window, centered around a single sensing condition
The sensor’s output is disabled during all TEACH and Set procedures, and is
enabled upon return to Run mode.
Following any TEACH or Set procedure other than Static TEACH, the Output ON
condition (Light- or Dark-Operate setting) remains as it was last configured. To
change that setting or the OFF-delay setting, see QS18Expert Sensor Setup.Figure 2. Dark Sensing Condition

Remote Configuration
Use the remote function to configure the sensor remotely or to disable the push button for security. Connect the white wire
of the sensor to ground (0V dc), through a remote programming switch. Pulse the remote line according to the diagrams in
the configuration procedures. The length of the individual programming pulses is equal to the value T: 0.04 seconds T
0.8 seconds
Push Button Enable/Disable
The remote input may be used to disable the sensor push button to prevent unauthorized adjustment. Connect the white
wire of the sensor as described above to perform the procedure below to either enable or disable the feature.
