Photoelectric Sensor with Built-in Amplifier (Ultracompact and Thin Type) E3T CSM E3T DS E 14 1 Photoelectric Sensor with Built-in Amplifier Contributes to Equipment Downsizing Ultracompact and Thin Photoelectric Sensor with Built-in Amplifier Easy optical axis adjustment with emitter fluctuation of 2% max. for Through-beam Models. Product lineup includes Coaxial Retro-reflective Models that support positioning applications. Product lineup includes BGS* Reflective Models unaffected by background (E3T-FL1 /-FL2 ). Product lineup of models with a variety of connection specifications. (e.g., robot cable and Smartclick pre-wired connectors) * BGS (Background Suppression) technology prevents detecting background objects. Be sure to read Safety Precautions on page 14. Features E3T-SR4 : Retro-reflective Sensor with Enhanced Compactness and High Performance Perform detection from a small hole. With a coaxial optical system, the lens diameter is only 2 mm. Sufficient incident light is obtained even through a small hole. The Coaxial Retro-reflective Sensor can be used for reliable application with positioning. Improved Stability of Short-distance Detection A detection distance as short as 10 mm can be used with a Tape Reflector. Detection is stable through a hole whether the distance is 10 mm or 100 mm (except in combination with the E39-R4).

Through-beam Sensors are normally sold in sets that include both the Emitter and Receiver. Orders for individual Emitters and Receivers are accepted. (Modifications are required for some models. Ask your OMRON representative for details.) *2. M3 mounting models are also available. These models have the M-suffix. Example: E3T-ST11M 2M Contact your OMRON representative for detail. *3. Ask your OMRON representative about the previous Retro-reflective Sensors: E3T-SR2 and E3T-SR3 . *4. Values in parentheses indicate the minimum required distance between the Sensor and Reflector. *5. Models are available either with or without the E39-R37-CA Reflector included. Model with E39-R37-CA Reflector: E3T-SR4 -S Model without Reflector: E3T-SR4 -C 2
