E3T-SL21 5M Omron

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.

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 included. Models with E39-R37-CA Reflector: E3T-SR4 -S Models without Reflector: E3T-SR4 -C *4. Models with robot (bending-resistant) cable are also available with R in the model number.
