Capacitive Sensors
Capacitive sensors can be used to detect metal objects as well as nearly all other materials. These sensors are often used in applications including level, and flow control for the detection of liquids, grains and powders.

Standard Capacitive Sensor Product features:

12, 18 and 30 mm cylindrical styles of stainless steel or plastic housings
5mm thin rectangular and long-range 80 mm x 80 mm x 40 mm styles
Sensor outputs of 3-wire DC and NAMUR output types
Models with hazardous area approvals
Magnetic Field Sensors
Our magnetic field sensor selection consists of the M12 housing style for traditional magnetic detection applications. Also offered is a non-contact, piston detection sensor for use with steel hydraulic cylinders. These magnetic sensors offer reliable piston magnet detection and are easily mounted, without the need for mounting slots or holes in the cylinder.
