WARNING: Not To Be Used for Personnel Protection
Never use this device as a sensing device for personnel protection. Doing so could lead to
serious injury or death. This device does not include the self-checking redundant circuitry necessary
to allow its use in personnel safety applications. A sensor failure or malfunction can cause either an
energized or de-energized sensor output condition.

2. Green LED
3. Gain adjuster
To install the S18-2 Sensor:
1. Align the sensor as required for the application. For the most sensitive object detection, align the sensor so that
the objects move across the sensor's axis.
2. Secure the sensor to a bracket.
3. Adjust the gain adjuster (sensitivity pot) if necessary.
4. Wire sensor as shown in the wiring diagrams.
