Balluff SK-3-6.5-NB Capacitive Proximity Sensor

Balluff SK-3-6.5-NB is a compact capacitive proximity sensor (mini sensor) in Balluff’s SENSORIK family, designed for non-contact object detection in tight spaces. The 6.5 mm diameter cylindrical housing yields a small-form-factor solution for automated production lines where space is at a premium, with Balluff’s robust construction typical of industrial sensors. As a capacitive switch, it detects changes in capacitance caused by nearby dielectric materials, enabling presence and level sensing of plastics, glass, liquids, powders, and other non-conductive objects through packaging, containers, or enclosure walls. It is marketed as a capacitive mini sensor within Balluff’s range and is designed to integrate with standard Balluff cabling and interfaces used for capacitive sensing, making it suitable for applications such as detecting small non-metal parts on conveyors or sensing objects in tight enclosures.
