Amplifier unit, not a sensor head
The E3C-GF4: It processes signals from a separate emitter/receiver pair, so the BOM line needs both the amplifier and the matching sensor head to complete the detection channel.

The E3C-GF4 is an amplifier unit designed to work with separate Omron photoelectric sensor heads. Compatibility depends on the specific head model and wiring configuration — confirm the head's output type and connector pinout against the amplifier's input requirements before specifying.
Alternative models and sibling configurations in the same Omron series. For obsolete or discontinued parts, these models can serve as compatible replacements or functional alternatives for plant maintenance.
