* Models numbers for Through-beam Sensors (E3S-AT@1) 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-AT21-L 2M), the model number of the Receiver, by adding "-
D" (example: E3S-AT21-D 2M). Refer to Ordering Information to confirm model numbers for Emitter and Receivers.
