FOTEK CDR-30X for M18 Tubular Type Photo Sensor

Description

The Fotek CDR-30X is an industrial-grade M18 cylindrical diffuse reflective photoelectric sensor engineered for precision target verification across automated assembly, packaging, and sorting machinery. Manufactured according to strict Original Engineering specifications, this sensor integrates modulated infrared emission circuitry with advanced ambient light rejection algorithms to deliver dependable non-contact presence sensing up to 300 mm. Its integrated dual-polarity (NPN and PNP) switching output architecture provides broad Technical Compatibility, allowing direct hardware integration into sourcing or sinking PLC digital input channels without supplementary relay logic or signal conditioning.

INDUSTRIAL APPLICATION SCENARIO
The Fotek CDR-30X is primarily deployed in automated carton handling and secondary packaging lines where varying package dimensions, matte coatings, and shifting ambient light profiles cause intermittent detection failures in non-stabilized optical sensors. The wide-beam 880 nm infrared spectrum effectively penetrates surface moisture and dust films common to production floors. By providing concurrent NPN and PNP switching signals, maintenance engineers can simultaneously trigger high-speed hardware input cards (e.g., Siemens or Omron PLCs) and direct pilot indicators, eliminating signal distribution bottlenecks during conveyor indexing operations.
