E3G-L77

Long-distance Photoelectric Sensor with Built-in Amplifier E3G E278-E1-6-1 Line of Long-distance Photoelectric Sensors for Large Workpieces Includes Retro- reflective Models with Sensing Distance of 10 m and Distance Settings Up to 2 m. Compact Retro-reflective models require less wiring and less space with a sensing distance as long as 10 m. Distance-setting models feature a teaching function. Stability indicator shows at a glance when operating conditions are stable. Relay and selectable NPN/PNP transistor outputs provided. Cable, standard connector, and terminal board models available. For the most recent information on models that have been certified for safety standards, refer to your OMRON website. Be sure to read Safety Precautions on page 8.
