Omron E3RB-DP22 Photoelectric Sensor is a radial, diffuse-reflective sensor used in industrial automation. It features a 300 mm sensing distance, a 10 to 30 VDC power supply, PNP output (Light-ON/Dark-ON selectable), and IP67/IP69K protection. The Omron E3RB-DP22 Photoelectric Sensor is built in an M18 metal housing with an M12 connector and a single-turn sensitivity adjuster, and it belongs to the E3RB Series for factory and process-line detection tasks.
Designed for conveyors, packaging, assembly, and material-handling systems, this sensor provides reliable presence and position detection with fast 0.5 ms response time and stable output for PLC inputs. Omron sensor durability reduces maintenance needs in washdown and dusty environments while the radial sensing geometry simplifies alignment on short-range targets.
Omron E3RB-DP22 Photoelectric Sensor is the main model for PNP, M12-connector installations; related variations include Omron E3RB-DN22 Photoelectric Sensor which offers an NPN output option for legacy control systems, Omron E3RB-DP12 2M Photoelectric Sensor supplied with a pre-wired 2 m cable instead of an M12 connector for fixed installations, and Omron E3RB-RP21 Photoelectric Sensor that uses a retro-reflective method to extend detection range up to several meters when paired with a reflector. Each linked product name clarifies the variation (output type, connection style, or sensing method) so users can quickly select the correct configuration.
Technical teams choosing the Omron E3RB-DP22 Photoelectric Sensor get a compact metal M18 sensor with reliable PNP switching and industrial ingress protection suitable for Indian manufacturing lines. Omronβs established supply and documentation make the E3RB Series a practical choice where repeatable short-range detection, ease of wiring, and resistance to washdown conditions are required. The sensorβs indicators and single-turn adjuster simplify commissioning and on-site tuning for stable production uptime.
