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...
