Modern light sensors for industry and automation solutions

Light sensors are among the key components of modern automation technology. They detect light sources, detect objects without contact and enable precise processes in machines and systems. As a distributor of high-quality light sensors, Rotima AG offers a carefully selected range for demanding applications in electrical engineering, mechanical engineering and industrial production.

Our product portfolio includes transmissive photointerrupters, reflective sensors and infrared LEDs for encoder and automation systems. Thanks to their technical precision, compact design and high detection accuracy, the light sensors are ideal for applications such as paper flow control, barcode reading, position detection and non-contact object detection.

Light sensors for industrial object detection and position control

Light sensors, such as those used in the electronics industry, typically consist of a light source - usually an infrared LED - and a light-sensitive receiver such as a photodiode. In the case of transmissive photointerrupters, the transmitter and receiver are integrated opposite each other in a housing. An object that interrupts the light beam is thus reliably detected. Photo-reflectors, on the other hand, detect light that is reflected back from the object, which is particularly useful for barcode readers and position checks.

In close cooperation with leading manufacturer Okaya Electric Industries, Rotima AG offers a wide range of light sensors that are characterized by their precise optical alignment, compact design and high interference immunity - ideal for demanding industrial applications.

Transmissive and reflective light sensors for industrial applications

Light sensors are used in a wide range of industrial and electronic applications where non-contact and precise detection of objects or movements is required. In printers and copiers, transmissive photointerrupters from Okaya Electric Industries reliably detect the flow of paper and thus prevent misfeeds or paper jams. In ATMs, the sensors detect fed banknotes and ensure exact positioning inside the machine.

Light sensors are also indispensable in the field of automated production. In encoder applications, infrared LEDs serve as a light source for detecting rotary movements and positions in drive or robot systems. In addition, reflective sensors are used for edge detection or for detecting markings on labels or packaging.

The light sensor solutions available from Rotima AG offer maximum precision and operational reliability, even under difficult environmental conditions. The light sensors therefore make an important contribution to quality assurance and increased efficiency in modern electronics and automation processes.
