Industrial Applications

1. Package Presence Detection in Dusty Ceramic Plants

Using the sensor's long 15m sensing range [1.2.2] and strong modulated infrared beam (870 nm) which penetrates air-borne particles, this thru-beam sensor is placed along high-dust conveyor lanes where clay and ceramic dust are prevalent. It detects the presence or transit of cardboard packages or raw ceramic tiles.

Problem Solved

Standard red-light photoelectric sensors often fail in dusty ceramic or cement processing plants because airborne particulates scatter the visible light, causing false triggers. The CX-412-P's high-penetration infrared LED and IP67 rating ensure uninterrupted operation despite high dust concentration.

2. Beverage Bottle Counting on Wash-down Conveyor Lines

The sensor is installed on automated beverage bottling lines to count filled opaque bottles. It utilizes the IP67-rated enclosure and ethanol-resistant polycarbonate covers, which withstand periodic washdowns and chemical sanitization.

Problem Solved

Washdown procedures with aggressive chemicals and ethanol-based sanitizers in food & beverage facilities degrade standard plastic optical covers, leading to cloudiness and sensor failure. The CX-412-P's specialized chemical-resistant acrylic and polycarbonate covers prevent degradation, and its 1ms response time supports high-speed counting.

3. Overhead Crane Collision Avoidance in Multi-Bay Metal Processing Shops

Sensors are mounted on the ends of multi-bay overhead cranes running on the same track, with the emitter on one crane and the receiver on the adjacent crane. The 15m sensing range provides an active optical barrier to trigger slow-down or stop sequences via PNP outputs.

Problem Solved

Metal processing shops often have oil mists, weld smoke, and long distances between equipment. The CX-412-P solves this because its high-power infrared beam can pierce oil mists, its 15m range easily covers safe deceleration buffers, and its robust PBT construction resists vibrations (10 to 500 Hz).
