Ultracompact, Ultrathin Photoelectric Sensor with Built-in Amplifier E3T The Improved E3T Series with Easier, Smoother Mounting and Installation • The series includes Through-beam, Long-distance (2 m) Sensors (E3T-ST3@). • Easy installation with M3-mounting Sensors (E3T-ST@@M, E3T-FD@@M, and E3T-SL@@M). • Small Cylindrical Sensors for one-point mounting are also available (E3T-C@@@(S)). • Infrared Sensors added to the Series (E3T-@T@@(M)F). 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 15. Lineup Overview Sensing method Rectangular type Flat Cylindrical type

Ordering Information Sensors [Refer to Dimensions on page 16.] I I Red light I I Infrared light M2-mounting Sensors A set of mounting screws is included with the Sensor. *1. The model number of the Emitter is expressed by adding an "L" to the set model number in the table. Example: E3T-ST11 -L 2M The model number of the Receiver is expressed by adding a "D" to the set model number in the table. Example: E3T-ST11-D 2M *2. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. *3. Models are available either with or without the E39-R37-CA Reflector...
