Through-beam Emitters

* Models numbers for Through-beam Sensors (E3S-AT

@@) 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: E3S-AT31-L 2M), the model number of the Receiver, by adding "-D"

(example: E3S-AT31-D 2M). Refer to Ordering Information to confirm model numbers for Emitter and Receivers.
