01 / Overview

Sensor Reflector Accessory for Reliable Retroreflective Sensing

E39-R1S is an Omron reflector accessory in E39 family, intended for use with compatible retroreflective photoelectric sensors. Reflector selection significantly affects detection stability, particularly in environments with target variation, vibration, or challenging background conditions. This model is commonly used in conveyors, packaging machines, and part transfer stations where predictable optical return is necessary for reliable sensor switching. During implementation, teams should evaluate mounting angle, reflector cleanliness, distance, and vibration robustness to prevent intermittent detection faults. It is also important to validate compatibility with the selected sensor model and required sensing distance. E39-R1S is generally chosen when integrators need a standardized reflector component that supports repeatable commissioning and easier maintenance across machine fleets.

Typical Applications

  • Retroreflective object detection on conveyors
  • Packaging station sensor setups with reflector target
  • Transfer point detection in assembly modules
  • Sensor retrofit maintenance where reflector is worn or missing
  • Machine commissioning requiring controlled reflective reference
  • Standardized sensor accessory stocking across plants

Buying Checklist

  • Confirm reflector compatibility with chosen sensor series and distance.
  • Validate mounting angle and bracket rigidity in operating conditions.
  • Keep reflector surface clean to avoid missed detections over time.
  • Check environment for dust, oil mist, or impact exposure risk.
  • Maintain spare reflector inventory for critical sensor stations.

Frequently Asked Questions

What's the sensing distance with this reflector?

Depends on sensor model. Typical: E3Z-R: up to 4m, E3FA-R: up to 3m, E3T-R: up to 1m. Larger reflectors (E39-R4) provide longer range.

How do I mount this reflector?

Two options: 1) Adhesive backing (clean surface, peel and stick), 2) Screw mount through center hole (M3 screw). For permanent installation, screw mount is more secure.

Can I use this reflector outdoors?

Yes, but protect from direct sunlight and moisture. UV exposure degrades reflective coating over time. Consider protective housing for outdoor installations.

How do I clean the reflector?

Use soft cloth with mild soap solution. Don't use abrasive cleaners or solvents. Scratches reduce reflectivity. Replace if heavily scratched or yellowed.
