Compact sensor design for easy and efficient integration. The photoelectric sensors are housed in a robust, compact cubic enclosure with a standardized hole spacing, enabling quick and easy mounting. The M3 internal thread provides flexible mounting options and facilitates adaptation to your specific requirements. A visible red light spot simplifies sensor alignment, while infrared versions operate reliably even in challenging environmental conditions. Various connection options, such as 4-pin or 3-pin M8 connectors, 2 m cables, and M8 pigtail variants, offer technical flexibility, ensure seamless integration into existing systems, and reduce downtime. The BOS sensors are equipped with a rear-mounted NO/NC switch for easy configuration. Clearly visible LEDs provide immediate visual feedback: green for operating status and stability indication, and yellow for switching state. Thanks to these 360° visible LEDs, you can monitor the status of your sensors at all times, quickly identify faults, and increase system availability. The robust plastic housing with IP67 protection class ensures a long service life.
