The Omron E3Z-LS61 2M is a distance-setting photoelectric sensor – you adjust the cutoff distance, not just on/off against a fixed background. The red LED source at 680 nm gives good contrast against white or light-colored targets. Sensing range is 20 mm to 200 mm on a 100×100 mm white paper reference. The NPN open-collector output sinks current to ground, so it pairs with most PLC sourcing inputs; verify your card expects NPN before committing the BOM line. Connection is pre-wired with a 2 m cable – no connector to source separately, but the cable length is fixed; if your panel layout demands a shorter pigtail, you'll need to cut and terminate or request a different variant. The lifecycle stage is current, meaning Omron still manufactures this code, so the supply chain is direct without a last-time-buy window.

Frequently asked questions
Will the E3Z-LS61 2M drop into a panel wired for the E3SGS3E4?
No. The E3SGS3E4 is a fork-type photoelectric sensor with a fork aperture and zinc die-cast housing. The E3Z-LS61 is a distance-setting rectangular sensor with different mounting dimensions and a different sensing principle. The only common points are the NPN output and 2 m cable length, but mechanical fit and sensing behavior differ completely.
