Small, flexible and easy to integrate into different machine environments: all these requirements are met by the new photoelectric sensors of Contrinex’s short M18 series. This includes reflex, through-beam and diffuse sensors with or without background suppression. The small plastic housings with M18 diameter are only 33 mm long in the cable version or 37 mm in the connector type. Sensors are embeddable and easy to install even in confined spaces. Background suppression types feature a pinpoint LED and specially adapted optics, ensuring excellent characteristics. All PNP versions include IO-Link communication, a key enabling technology for Industry 4.0 and the Industrial Internet of Things.
