A reflex, or reflective, photoelectric sensor contains a transmitter and a receiver in a single housing, and emits a pulsed, focused light beam through a polarization filter toward a distant reflector. Reflected light returns to the sensor, passing through a second filter before arriving at the receiver. When a target object interrupts the light beam, the receiver detects the reduced light intensity and triggers the sensor.

CONTRINEX C-12 Subminiature Photoelectric Sensors Distributors


The Contrinex Subminiature range packs exceptional position- and presence- sensing performance into the smallest self-contained photoelectric sensors on the market. Through-beam or diffuse sensors in Ø 4 and M5 cylindrical or 5 mm x 7 mm rectangular stainless-steel housings offer multiple mounting methods and possibilities for beam orientation. For fully embedded applications, sensors with spherical sapphire-glass lenses produce focused, cylindrical light beams.

Best-in-class sensing distances of up to 90 mm (diffuse) and 250 mm (through-beam) allow sensors to be positioned at a safe distance from the target, minimizing the risk of accidental impact damage. Thanks to robust construction that includes rugged sensing faces, Contrinex Subminiature sensors are resistant to chemical contamination and abrasion, delivering maximum operational uptime and world-class reliability.

CONTRINEX Cylindrical Miniature M12 Standard Size Photoelectric Sensor Distributor


Contrinex Miniature photoelectric sensors provide market-leading performance and reliability in rugged, industrystandard housings to ensure excellent resistance to machine vibration or shock from accidental impact. They are recommended for general automation in the printing, packaging or machine tool industries, and for electronic assembly or mechanical handling systems.

Ideal for applications where space is tight, they also offer excellent sensing distances. Available technologies include diffuse sensing, polarized retro-reflective sensing, through-beam sensing and amplifiers. Versions with excellent background suppression allow ultra-reliable target detection, even against light backgrounds. For applications where precise sensing is required but space is limited, the range includes fiber-optic ampli-fiers that allow the sensor housing to be mounted remotely.

Contrinex M12 photoelectric sensors are ideal for high-speed applications in the most challenging environments, with the 1121L capable of detecting even the smallest targets. This laser throughbeam sensor is suitable for extended sensing ranges up to 50 meters and has a 1000 Hz maximum switching frequency.

CONTRINEX Cubic Small Photoelectric Sensor for Demanding Applications Distributor


Contrinex Small photoelectric sensors are rugged and highly reliable. Cubic (40 mm x 40/50 mm) models are suitable for industrial applications including packaging and wrapping machinery, filling systems and general automated equipment. Available in diffuse (energetic or background-suppression), polarized and non-polarized reflex or through-beam technologies with glass or coated-plastic windows, they are insensitive to high levels of ambient light.

Cylindrical M18 models are ideal for demanding industrial environments, including automotive assembly, packaging machinery, conveyor systems and general automation equipment. A comprehensive range comprises diffuse sensors (both energetic and background-suppression variants), retro reflective sensors and through-beam sensors with the option of either axial or lateral sensing for sensing distances up to 50 meters.

CONTRINEX Cubic Compact Rugged Photoelectric Sensors Distributors

Cubic Compact

Designed from the outset to be cost-competitive without compromising performance, Contrinex 5050 photoelectric sensors pack an exceptional range of features into industry-standard 50mm x 50mm x 18mm housings. Equipped with a shatter-resistant PMMA acrylic-glass sensing face, the 5050 is at home in the most demanding environments including packaging and filling lines, conveyor systems and the machine tool industry.

The Contrinex C55 series (50 mm x 50 mm x 23 mm) uses time-of-flight (TOF) technology to measure long distances up to 5000 mm. With an IP 69K enclosure rating and Ecolab approval, these sensors are ideal for the food industry. A background suppression type is also available.

CONTRINEX Glass Optical Fibers for Photoelectric Switches Distributor

Glass Optical Fibers

Depending on the type involved, glass optical fibers consist of 200 to 5000 individual fibers with diameters of 30 to 50 µm. The fiber bundle is surrounded by a sleeve, which can be selected according to the application.

The sensing heads are available with straight or right-angle light outlets. The range comprises models for use as diffuse sensors (emitting and receiving fiber bundles in the same sleeve) and as through-beam sensors (the fiber bundles are in separate sleeves). In order to cover various application needs, a number of different bundle cross-sections are available: large cross-sections for long sensing ranges, small crosssections for short ranges, high resolutions, and detection of small objects.
