OMRON E3RA-DP22 Diffuse-Reflective Photoelectric Sensor – E3RA Series
Imagine a high-speed packaging line running at full capacity when a misaligned object passes undetected — the result is a jam, a machine fault, and costly unplanned downtime. In precision-driven industrial environments, the reliability of every sensing point is non-negotiable. The OMRON E3RA-DP22 photoelectric sensor is engineered to eliminate exactly these failure scenarios, delivering consistent, high-speed object detection even in demanding ambient conditions.
Within OMRON’s E3RA Series, the E3RA-DP22 occupies the diffuse-reflective (D) segment with NPN open-collector output — the configuration most widely specified by automation engineers for PLC-interfaced detection tasks. OMRON’s E3RA family is globally recognized as a workhorse sensor line, deployed across automotive, food & beverage, electronics manufacturing, and logistics sectors on every continent. The E3RA-DP22 specifically is a go-to choice for engineers who need a compact, cost-effective, and field-proven sensing solution without compromising on switching speed or environmental robustness.

Key Features & Benefits
- Diffuse-Reflective Detection: No reflector or separate receiver required — simplifies installation and reduces wiring complexity on tight machine frames.
- NPN Open-Collector Output: Directly compatible with the vast majority of PLC input modules (Siemens, Mitsubishi, Omron, Keyence, Allen-Bradley, etc.).
- Compact Form Factor: Fits into space-constrained machine cavities where larger sensors cannot be mounted.
- High Switching Reliability: Designed for repetitive, high-cycle detection tasks without signal degradation over time.
- Robust Housing: Resistant to vibration and industrial contaminants, suitable for factory floor deployment.
- Easy Integration: Standard M12 or pigtail connector options (confirm with OMRON datasheet) reduce commissioning time.
Industry & Equipment Applications
- Packaging & Labeling Lines: Object presence/absence detection on conveyor systems.
- Automotive Assembly: Part positioning verification on robotic work cells.
- Food & Beverage Processing: Container counting and fill-level monitoring.
- Electronics Manufacturing (SMT/PCB): Board detection and tray positioning.
- Logistics & Warehousing: Parcel detection on sorting conveyors.
- Semiconductor Fabs: Wafer carrier and cassette presence sensing.

Frequently Asked Questions
Q: Is the OMRON E3RA-DP22 compatible with PNP PLC input modules?
A: The E3RA-DP22 features NPN output. For PNP-input PLCs, please inquire about the E3RA-DP21 (PNP output variant) or use an NPN-to-PNP signal converter.
Q: What is the sensing range of the E3RA-DP22?
A: Please refer to the official OMRON E3RA-DP22 datasheet for the rated sensing distance. Konmask.com does not publish unverified specifications.
Q: Can I order a single unit for evaluation?
A: Yes. We accommodate single-unit sample orders. Contact us for pricing and lead time.
Q: Do you provide a warranty on this product?
A: We provide a supply authenticity guarantee. Manufacturer warranty terms apply as per OMRON’s standard policy. Contact us for details.
Q: How long does international shipping take?
A: Typical export lead time is 3–7 business days for in-stock items, depending on destination and chosen freight method (DHL, FedEx, sea freight, etc.).
Q: Can you provide an export invoice and packing list?
