SA1N-D□1VF50-2M
N: NPN Output
P: PNP Output● The output transistor becomes OFF when the SA1N shortcircuit or overload. Make sure all connections are correct
before turning the power on.

● After aligning the optical axis and adjusting the sensitivity,
use a detection object to block and unblock the light beam
several times to make sure that the both operation are within
the range that allows stable activation and deactivation.

● When using a DC power unit with an insulated transformer ora power supply, be sure to ground the FG (frame ground)terminal.

● Setting in the range which allows stable operation achieves
higher reliability against changes in the operating
environment generated after installation.

Brown: +V(1) Place a detection object at a given position and turn up theSensitivity adjustment volume from MIN. until the Operation
indicator (Orange) turns on (Point A).
(2) Remove the object and turn down the Volume from MAX. untilthe Operation indicator (Orange) turns off (Point B).
(MAX. is regarded as Point B if the Operation indicatordoesn’t turn off at MAX.)(3) Set the Volume at the middle point between Points A and B.
(2)● Clean the lens and the case by a soft and dry cloth eriodically.
Do not use organic solvents such as ammonia, caustic soda,
alcohol or thinner for cleaning.

All dimensions in mm.

● Be sure to route the sensor cables separate from any powertransmission or high voltage line, or else use shielded cables.
Using the same conduit or duct as high voltage or power lines
will cause malfunctions or damage because of electromagneticinduction.

● Turn off the power supply before the load, because the SA1N
will start to operate 100ms from turning on.

● After settng complate, make sure that both the Operation indicator(Orange) and Stability indicator (Green) and turns on when
the detection object is placed at the given position.

● Dispose of the SA1N as an industrial waste.

● Tighten the nuts with a torque of 1.0 N•m or less. The thread
may be stripped if an excess torque is applied.

● Check the mounting position and the optical axis before fixing
the product. Once the sensor is fixed, the mounting angle is not
adjustable.

● Avoid turning the power on and off consecutively.

SA1N Series
Diffuse reflective type● High frequency fluorescent lamps or inverters may cause
faulty operation as these equipment may emit light or noise ofsimilar modulated frequency that the SA1N generate.
Do not expose the receiver axis of the SA1N to sunlight orother direct light projections.
● A transient overcurrent may flow in when a capacitor or a coil
is connected to the load.
● When using the power supply with a large power supply
capacity, insert a fuse or breaker according to the number ofsensors used.
