T18-2 Epoxy Encapsulated Right-Angle Sensor
Datasheet
Next Generation of Self-Contained dc-Operated Sensors
•
•
•
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.
