Determine the time required for sensor operation to stabilize after the sensor is turned ON and take
appropriate measures, such as inserting an ON delay into the user program after turning ON the
sensor.
A programming example is shown below.
The sensor's power supply voltage is used as the input bit to
Sensor_power
.
A 100-ms timer delay (the time required for an OMRON Proximity Sensor to stabilize) is created in
the user program.
After the timer changes to TRUE, input bit

to change to TRUE after the input of
the sensor changes to TRUE.

Output Short-circuit Protection Function of the Built-in Output
If a load connected to the output terminals is short-circuited, output components and printed circuit
boards may be damaged. To guard against this, the PNP output type includes the short-circuit protec-
tion function.
When using the PNP output that does not include the short-circuit protection, incorporate a protective
fuse in the output circuit. Use a fuse with a capacity of around twice the rated output.
