* Models numbers for Through-beam Sensors (E3T-@T@@) are for sets that include both the Emitter and Receiver.
E3T-ST1@ (Receiver)
E3T-ST2@ (Receiver)
Through-beam Models (Flat)
E3T-FT1@ (Emitter)
E3T-FT2@ (Emitter)
E3T-FT1@ (Receiver)
E3T-FT2@ (Receiver)
Through-beam Models
(Side-view)
E3T-ST1@ (Emitter)
E3T-ST2@ (Emitter)
The model number of the Emitter is expressed by adding "-L" to the set model number (example: E3T-ST11-L 2M), the model number of the Receiver, by adding "-D" (example:
E3T-ST11-D 2M.) Refer to Ordering Information to confirm model numbers for Emitter and Receivers.
Emitter: E3T-ST@@-L
Receiver: E3T-ST@@-D
Emitter: E3T-FT@@-L
Receiver: E3T-FT@@-D
