In the datasheet the part number breakdown shows that it is a set of emitter and transmitter.

Hello @autem-services,

Welcome to the TechForum!

The light curtains appear to be sold in pairs.

This is based on:

- Datasheet uses a single part number (row) to identify emitter and receiver power consumption (columns)

- Datasheet comment about net and gross weight:

- A [configurator](https://www.fa.omron.co.jp/product/tool/safety-light-curtains_selector/f3sg-sr_pg/en/?_ga=2.255009480.1345538582.1790858634-1141395729.1790858634) that leads to a single part number.

- Lack of an emitter or receiver designator in the datasheet model number legend.

Sincerely,

APDahlen
