*1. Values in parentheses indicate the minimum required distance between the Sensor and Reflector.
*2. 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
Orders for individual Emitters and Receivers are accepted. (Modifications are required for some models.)
*3. Ask your OMRON representative about the previous Retro-reflective Sensors: E3T-SR2@ and E3T-SR3@.
*4. 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
