OMRON E39-R21 Reflector for Photoelectric Sensors

The OMRON E39-R21 (E39-R21) is a specialized reflector designed for use with retro-reflective photoelectric sensors in automated detection and material handling systems. Engineered to return emitted light beams directly back to the sensor optical receiver, this component ensures stable target detection across industrial sensing environments. It is deployed alongside compatible OMRON optical sensing equipment to reliably detect packaging, containers, pallets, and parts on high-speed conveyor lines, automated machinery, and assembly fixtures. Built for dependable operation in demanding factory conditions, the E39-R21 provides consistent retro-reflection to maximize sensing range and maintain optical alignment. Its robust housing protects the optical reflective surface against common industrial contaminants like airborne dust and minor vibrations encountered in packaging and sorting facilities. Serving as an essential replacement or maintenance component, this reflector supports trouble-free operation of sensor systems, preventing false triggers and helping maintain line uptime. The OMRON E39-R21 is suitable for manufacturing, logistics, and packaging equipment requiring precision photoelectric detection.
