* Models numbers for Through-beam Sensors (E3Z-T@@) are for sets that include both the Emitter and Receiver. 
The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3Z-T61-L 2M), the model number of the Receiver, by adding "-D" 
(example: E3Z-T61-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.
