White
Output 1
Output 2
Color code Output operation
Notes: 1) Make sure to connect terminals correctly as the sensor does not
incorporate a reverse polarity protection circuit.
Notes: 1) Further, the output is not incorporated with a short-circuit protection
circuit. Do not connect it directly to a power supply or a capacitive
load. Faulty wiring may result in damage.
Notes: 2) The color code of the connector attached cable is also the same.
Notes: 3) Ensure to insulate the unused output wire.
