Condition TEACH Result Display
One valid reference surface is taught
within sensing range
Sets a dual (intensity + distance) window
centered around the taught reference
surface. The ± window size is the
previously used switching threshold, or
75% by default.
The switching threshold flashes on the

One reference surface is taught outside
the sensing range
Sets a dual (intensity + distance) window
centered around the taught reference
surface that is outside the sensing range.
The sensing conditions may not be as
reliable.

3.7 Pulse Frequency Modulation (PFM) Output
The Q4X can generate pulses whose frequency are proportional to the sensor's measured distance, thereby providing a method for
representing an analog signal with only a discrete counter. The sensing range of the sensor is scaled from 100 to 600 Hz (100 Hz
equals the near range limit of the sensor, 600 Hz equals the far sensing range limit). An output of 50 Hz represents a Loss of Signal
(
) condition where there is no target or the target is out of the sensor's range.
3.8 Sync Master/Slave
Two Q4X sensors may be used together in a single sensing application. To eliminate crosstalk between the two sensors, configure
one sensor to be the master and one to be the slave. In this mode, the sensors alternate taking measurements and the response
speed doubles.
Important: The master sensor and the slave sensor must be programmed for the same Response Speed and Gain and
Sensitivity settings. The master sensor and slave sensor must share a common power source.

the first sensor as the master; navigate:

2. Configure
the second sensor as the slave; navigate:
