Industrial Sensors

Photoelectric & Proximity Sensors

Photoelectric sensors rely on consistent optical performance to detect presence, position, and movement. Epolin dyes enable wavelength-specific filtering that improves detection accuracy and reduces interference from ambient light.

Applications include:

• Through-beam IR sensors
• Retro-reflective sensors
• Diffuse sensors
• Object detection and counting systems

Dye formulations can be tuned to match common industrial emitter wavelengths while blocking unwanted light.  Dyes can be incorporated into Polymers that are clear or transparent, allowing detection with a sensor.

Machine Vision & Inspection Systems

Machine vision systems require precise control of illumination and detection wavelengths to ensure reliable inspection and measurement. Epolin dyes help optimize optical paths and reduce noise from stray or reflected light.

Example applications:

• Camera filters and sensor windows
• Illumination control components
• Optical contrast enhancement elements
• Light-managed enclosures and housings

Infrared (IR) & Near-Infrared (NIR) Sensing

Many industrial sensors operate in the NIR region for distance measurement, material detection, and monitoring applications. Epolin dyes enable selective transmission or blocking of NIR wavelengths while maintaining desired visible appearance.

Applications include:

• NIR-pass / visible opaque filters
• Sensor windows and covers
• IR-based monitoring systems
• LiDAR systems and sensors

Automation, Robotics & Safety Systems

Robotics and automated equipment rely on optical sensors for navigation, positioning, and safety. Epolin dyes support consistent optical performance in environments with dust, vibration, and variable lighting.

Example uses:

• Light curtains and safety barriers
• Robotic vision systems
• Position and alignment sensors

Process Monitoring & Analytical Equipment

Optical sensing is widely used in industrial process monitoring and analytical instrumentation. Epolin dyes allow optical performance to be built directly into components used in these systems.

Applications include:

• Optical flow and level sensors
• Analytical instrument windows
• Light-managed tubing and housings

Material & Process Compatibility

Epolin dyes are compatible with many materials and manufacturing processes commonly used in industrial sensor production, including:

• Injection molding
• Extrusion
• Coating and over-molding
• Printing and marking

Dyes can be incorporated into plastics, epoxies, inks, and coatings to meet specific optical requirements.

Why Epolin for Industrial Sensors?

• Spectral Precision – Targeted absorption from UV through NIR
• Ambient Light Control – Reduced interference and improved signal quality
• Low Loadings – High performance at minimal dye concentrations
• Material Compatibility – Works in common industrial polymers
• Optical Consistency – Reliable batch-to-batch performance
• Application Support – Guidance for wavelength selection and system integration

-Development & Integration Support-

Epolin works with sensor manufacturers, automation OEMs, and system integrators to support development and production by providing:

• Technical and spectral data
• Computer modelling of dye formulations to match target specifications.
• Incorporation of dyes into Polymers, Inks, and Coatings
• Support for prototyping and scale-up

Final sensor performance depends on system design, material selection, and application conditions.
