The Omron E3S-R2E42-40 Through-Beam Photoelectric Sensor is a through-beam detector in the Omron E3S series, designed to sense objects by interrupting a dedicated light beam between an emitter and receiver. It is commonly used in industrial automation on conveyors and packaging lines where reliable long-range detection is required, or where indirect ambient light can affect other sensor types. The model designation E3S-R2E42-40 identifies a specific through-beam configuration within Omron's E3S family, aligning with standard Omron electrical interfaces and mounting practices.
