Complete family of sensors, all housed in the compact right angle 18 mm threaded housing designed for long
service life in wet environments
ECO-Lab certified chemically robust epoxy encapsulated plastic sensors for wash-down applications typically
found in the food and beverage industry
Epoxy encapsulation of electronics provides a redundant seal in addition to plastic ultrasonic weld joints for
maximum reliability in wet thermal shock environments
Permanent laser etched product marking will not wear off after repeated cleaning cycles
Food grade plastic materials used for all exposed surfaces
Hygienic shape for easier cleaning of the sensor
Powerful and bright visible red emitter beam for easy alignment and set-up
Highly visible output and dual-function power and stability indicators
Advanced ASIC technology makes sensor resistant to optical and electrical noise source
Wide operating temperature range: –40 °C to +70 °C (–40 °F to +158 °F)
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.
Models
Integral 4-pin M12/Euro-style quick disconnect models are listed.
• To order the 2 m (6 ft) cable model, replace the suffix "-Q8" with "-2M"
• To order the 9 m (30 ft) cable model, replace the suffix "-Q8" with "-9M"
Models with a quick disconnect require a mating cordset.

Gain
Adjustment *
To install the T18-2 Epoxy Encapsulated Right-Angle 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. Wire sensor as shown in the wiring diagrams.
4. Adjust the gain adjuster (sensitivity pot) if necessary.
