*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 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.
