Contrinex manufactures photoelectric sensors as small as 4mm in diameter. These fully functional, self-contained photoelectric sensors are offered in various sensing technologies. An exceptional subset of the M5 sensors is the diffuse sensors with a sapphire lens, which UK representative Plus Automation says provide unparalleled performance in a compact housing.

The photoelectric sapphire sensors are recognised for their small size, energy-efficient design and high-quality optics, which provide a narrow sensing beam, enabling them to excel even in the most compact spaces.
Ease of installation is assured because no adjustment is required, thanks to their integrated electronics. The sensor is easy to integrate and mount using brackets or drilled holes. The high-quality optics provide such a tightly controlled, narrow beam that the sensor can be mounted recessed to provide impact and abrasion protection.
A typical usage is integrating the sensor into transfer tables to detect the passage of sheets with precision. The spherical lens design ensures that debris doesn't impede its function, guaranteeing smooth operation even in dusty environments.
Similarly, it is widely employed in detecting weld points, subtle differences in surface appearance with unparalleled accuracy, and numerous other applications, including the detection of plastic films.
The sensors' small size and high performance enable many customers to use them instead of fibre-optic sensors. They prefer that they are self-contained, have cabled connections, and provide price and cost savings.
