Capacitive Proximity Sensors

Need help selecting a sensor for Object Detection?
Use our selection assistance tool to narrow your search.

Capacitive sensors detect both metal and non-metal objects, can sense through insulating materials, and are often used to detect fill levels of liquids, pellets, and powders through container walls. They are available in round (tubular) or rectangular shapes, with sensing distances up to 40mm.

Capacitive Proximity Sensors

Capacitive proximity sensors are non-contact sensors that generate an electrostatic field to detect metal and non-metal objects. Using two conduction plates, they sense the change in capacitance when an object moves within their sensing range. They can even sense through insulating materials, such as wood or plastic, and offer an ideal solution for non-invasive detection of liquid, pellet, and powder levels as they can be mounted externally and sense through storage container walls. Flush-mounted sensors are embeddable, while non-flush sensors allow longer sensing distances, are non-embeddable, and their sensing face must protrude from the mounting substrate.

Sensing distances range from 1.5 to 15 mm (flush mount) and 2 to 40 mm (non-flush (extended sensing face))
Normally open or normally closed, NPN and PNP logic outputs available
LED status indicators verify operation at the sensor
