Eaton Electrical
Comet Series Photoelectric Sensors

Key Features

  • Industry standard 18 mm diameter threaded body has flat sides allowing it to be mounted like a tubular sensor or against any flat surface
  • Right Angle viewing models mount in a depth of only 6/10th of an inch
  • Perfect Prox technology provides exceptional background rejection and application problem-solving
  • Visible sensing beams let you see where the beam is aimed for quick setup and alignment
  • Solid polyurethane housing completely encapsulates internal circuits for high resistance to shock and vibration
  • Adaptable modulation circuit provides immunity to crosstalk from other closely mounted sensors
  • The industry’s only background rejection sensors with a two-wire circuit design
  • Models available with both AC and DC operation in a single unit—up to 264 Vac 
  • Four-wire DC sensors offer both NPN and PNP outputs
  • Output status indicator visible from a wide 270° angle

Standards and Certifications

  • UL Recognized
  • cUL Recognized
  • CE (except two-wire DC models)

The Comet Series from Eaton’s Electrical Sector is a complete line of high performance, 18 mm tubular sensors with a variety of models and modes to solve virtually any sensing problem.

The sensors are available in thru-beam, reflex, polarized reflex, diffuse reflective, focused diffuse reflective, wide angle diffuse reflective, Perfect Prox, fine spot Perfect Prox and fiber optic sensing. Perfect Prox is one of the most powerful problem-solving sensors available. These sensors can reliably detect targets of different color, reflectance, contrast or surface shape at the same range, while ignoring background objects just a fraction of an inch away.

The Comet Series includes AC/DC and DC-only models with two-, three- and fourwire circuitry. Choose from cable or micro-connector. Mini-connectors are available on two-wire models for easy retrofit. Each sensor features a Light/Dark Operation switch and a gain control to provide for quick adjustment to peak optical performance.

The unique threaded body with flat sides allows quick mounting in a 3/4 inch hole or against any flat surface. Internal components are rigidly sealed in a solid encapsulated package for excellent performance in high-vibration and high-shock applications.
