Omron E3NT DATASHEET

Harsh environment long distance photoelectric Sensor in metal housing
E3NT
• 4 Diffuse reflective E3NT-L application optimized models:
• Extra long distance type for setting
distances up to 3 m
perature environments
• Analog output type for distance in-
formation
• Fast response type for high speed
detection and counting
• Retro reflective E3NT-R models with sensing distance up to 16 m
• Two programmable outputs for ’win­dow teaching’
• Double triangulation for stable detec­tion of reflective objects
• IP67 and IP69k for highest resistance in wet environments
E3NT
Condensation in often cleaned envi­ronments or due to rapid temperature changes is prevented by the complete­ly sealed housing of the E3NT and the optional window heating.
Application
With the optic link, the sensor can be remotely set and checked while it is op­erating in an area where access is re­stricted.
This robust sensor is ideal for opera­tion in harshest environments.
