Contrinex Photoelectric Sensors

Photoelectric Sensors

Photoelectric

A reflex, or reflective, photoelectric sensor contains a transmitter and a receiver in a single housing, and emits a pulsed, focused light beam toward a distant reflector. Reflected light returns to the sensor, arriving at the receiver. When a target object interrupts the light beam, the receiver detects the reduced light intensity and triggers the sensor. The relatively high level of reflected light allows reflex sensors to achieve sensing distances up to eight meters. For applications where the target object itself reflects light back toward the sensor, models with polarization filters are available.

Contrinex C23 Photoelectric Sensors

C23 Sensors

The C23 Series of photoelectric sensors includes diffuse, reflex, through-beam and background suppression types. They reliably detect objects of different colors and material types, even under difficult conditions. All PNP switching versions of this sensor series are equipped with IO-Link, preparing them for machine-to-machine communication within the context of the Internet of Things.

The C23 Series of powerful photoelectric miniature sensors are the perfect allrounders. They combine a reduced size (20 x 30 x 10 mm) with best-in-class sensing ranges and reliably detect even fast moving objects. In addition, specially developed Contrinex optics provide excellent black/white performance for the sensor version with background suppression. Typical applications include conveyor belts used in production and automated food packaging.

  • Data monitoring and diagnosis of sensor functions
  • Sensitivity adjustment and teach-in
  • Choice of switching type and configuration of switching behavior
  • Setting of sensor mode and – for through-beam types – selection of emitting sequences
  • Detection counter and temperature measurement

Contrinex Applications

Filling Machines

Filling machines are widespread in many industries, including solids handling, chemical, food, beverage and pharmaceutical, often operating continuously around the clock. Industrial sensors detect containers, lids, labels and caps, measure fill levels and more, and play a vital role in keeping automated filling equipment running reliably, accurately and with minimal downtime.

Machine Tools

Machine tools impose harsh operating conditions on the sensors needed to control cutting, forming and joining processes that run continuously in many metalworking factories. Common hazards include cutting fluid, cooling sprays, swarf particles and electromagnetic interference, making sensor selection particularly difficult where world-class performance is essential.

Packaging Machines

On the journey from manufacturer to consumer, packaging protects all types of product, including foods, pharmaceuticals, white goods and cosmetics. Although packaging helps bring competitive products to target markets in the best possible condition, costs are often significant, and automation helps minimize the impact.

Special Purpose Machines

Special-purpose machines exploit the versatility and convenience of sensor technology for tasks that range from simple position sensing to complex feature detection and identification, in applications as diverse as electronic assembly and plastic molding. Sensor adaptability is also crucial to the economics of one-off and customized machine production.

Textile Machines

Machinery manufacturers supplying the textile, leather and clothing industries rely on sensors for efficiency, reliability and precision. World-class accuracy is essential for production of technical textiles and for making the carbon or chemical fibers used in modern, innovative products, often in highly automated factories.
