Official Part Number E3Z-LS61 2M
GTIN Standard 4547648677011

Technical Overview

The Omron E3Z-LS61 2M is a compact, distance-settable photoelectric sensor featuring built-in background suppression (BGS). Engineered with a robust Polybutylene terephthalate (PBT) housing rated at IP67, it resists industrial dust and water ingress. It operates on a 12-24 VDC power supply and delivers an NPN open collector output with an ultra-fast 1 ms max response time. The sensor offers an adjustable sensing range from 20 to 200 mm utilizing a visible red LED (670 nm) light source, providing reliable detection irrespective of target color or background reflectivity. The unit includes a 2-meter pre-wired cable and switchable Light-ON/Dark-ON operation.

Key Features
