Omron E39-R10 Retro-Reflective Photoelectric Sensor Reflector

Model Identifier E39-R10
Official Part Number E39-R10
GTIN Standard 4536854515217

Technical Overview

The Omron E39-R10 is a high-performance retro-reflective mirror engineered for reliable object detection when paired with Omron photoelectric sensors (such as the E3ZM and E3Z series). Constructed with a durable acrylic optical face and a rugged ABS base, this passive reflector delivers a robust IP67 degree of protection, making it ideal for dusty or wet industrial environments. It features a wide minimum directional angle of 30 degrees, ensuring a strong and consistent light return even when optical sensor alignment varies slightly. Designed for extreme environments, the E39-R10 can withstand ambient operating temperatures ranging from -40°C to 60°C, ensuring reliable operation in freezers, cold storage, or outdoor installations. Measuring 61.4 mm by 51.6 mm with an 8 mm depth, it integrates easily into tight spaces and machinery utilizing a simple two-hole screw-mount design.

Key Features

  • Optimized for compatibility with Omron retro-reflective photoelectric sensors, including E3ZM and E3Z models.
  • Exceptional optical return featuring a 30° minimum directional angle to accommodate minor mounting misalignments.
  • Extended thermal endurance with a wide operating temperature window of -40°C to 60°C.
  • IP67 degree of protection ensures rigorous resilience against dust and high-pressure fluid ingress.
  • Rugged industrial construction utilizing Acrylic for the optical face and ABS for the supportive housing.
  • Compact 61.4 mm x 51.6 mm x 8 mm footprint with two pre-drilled mounting holes for rapid, secure installation.

Passive optical component; requires zero electrical power for operation.

Industrial Applications

1. Cold Storage Conveyor Detection

Used as the passive target for retro-reflective sensors detecting boxes and pallets on automated conveyors inside industrial freezers and cold storage facilities.

Problem Solved

Standard optical components can crack or fail in extreme cold. The E39-R10 reliably operates down to -40°C, providing a durable optical target without the need to route electrical power to the opposite side of the conveyor system.

2. Washdown Food Packaging Lines

Verifying the presence of bottles or food containers passing through a high-pressure washdown zone in a food and beverage manufacturing plant.

Problem Solved

Splash zones quickly destroy non-sealed components. The IP67 rating ensures the reflector maintains its internal optical integrity despite frequent moisture exposure, while the acrylic material resists chemical degradation.

3. AGV Docking Alignment Verification

Acting as a robust stationary optical target for Automated Guided Vehicles (AGVs) equipped with alignment sensors to verify positioning at charging stations.

Problem Solved

Mechanical vibrations and slightly off-axis approach angles can cause sensor misalignment. The 30-degree minimum directional angle of the reflector safely accommodates these minor angular deviations, guaranteeing a stable beam return and flawless docking.
