Industrial Applications

1. Transparent PET Bottle Counting on Conveyors

High-speed detection and accurate tracking of transparent polyethylene terephthalate (PET) bottles on automated beverage conveyor systems.

Problem Solved

Standard photoelectric sensors fail to detect transparent plastics because the emitted light passes through the bottle without sufficient attenuation. The CX-482's retro-polar optical design accurately senses refractivity shifts in transparent materials, guaranteeing zero missed bottle counts.

2. Food Processing Washdown Packaging Lines

Presence detection of packaged foods in areas subjected to routine chemical sanitation and sterilization using ethanol-based detergents.

Problem Solved

Standard acrylic-lensed sensors crack, haze, or discolor when exposed to alcohol-based detergents over time. The CX-482 utilizes high-strength, ethanol-resistant polycarbonate optical and indicator covers alongside an IP67 rating, maintaining optical clarity and sealing integrity during intense washdown protocols.

3. Dual-Lane Narrow-Pitch Film Feeding

Side-by-side sensor deployment to monitor film tension, edge presence, or sheet feeding across highly adjacent material feed tracks.

Problem Solved

Placing traditional photoelectric sensors directly next to one another typically results in optical cross-talk, leading to erratic output states. The CX-482 features a built-in automatic interference prevention system that prevents mutual optical interference, enabling close-proximity dual-lane mounting.
