Photoelectric Sensors Technical Guide
Power Supply
When using a commercially available switching regulator, ground the
FG (frame ground) and G (ground) terminals.
If not grounded, switching noise in the power supply may cause
malfunction.
Example of Connection with S3D2 Sensor Controller
DC Three-wire NPN Output Sensors
Reverse operation is possible using the signal input switch on the
S3D2.

● Mounting
Attachment to Moving Parts
To mount the Photoelectric Sensor to a moving part, such as a robot
hand, consider using a Sensors that uses a bending-resistant cable
(robot cable).
Although the bending repetition tolerance of a standard cable is
approximately 13,000 times, robot cable has an excellent bending
tolerance of approximately 500,000 times.
Cable Bending Destruction Test (Tough Wire Breaking
Test)
With current flowing, bending is repeated to check the number of
bends until the current stops.
