SICK Expands its Capacitive Sensor Line with New AC Sensors
Minneapolis, Minn. October 25, 2004 - SICK, one of the world's leading manufacturers of sensors, safety systems and automatic identification products for industrial applications, today announced its new CM 30 AC Capacitive sensors. The CM 30 line is available in a 2-wire design for an operating voltage of 250 V AC in 30 mm barrel style. Features include high immunity to electromagnetic interference, switching distances of up to 25 mm, and options for flush or non-flush installation. The ranges of the CM 30 sensors are 25 mm with non-flush installation and 16 mm with flush installation. The sensors' response sensitivity can be adjusted via a potentiometer. All devices offer an enclosure rating of IP 67 and are available with M12 plugs or a 2 m connection cable. UL and CSA approvals have also been obtained.
Capacitive sensors are ideal for use in applications where photoelectric sensors are unsuitable due to oil, dirt, dust and other particles in "dirty" industrial environments such as machine tool manufacturing. Photoelectric sensors can experience difficulty in such applications, while capacitive proximity sensors are less sensitive to dust and dirt particles. Some machine tool application examples include coolant fluid fill level sensing through plastic tanks and displacement of non-metal parts.
The CM 30's high electromagnetic compatibility (EMC) reliably prevents false switching resulting from, for example, electrostatically charged granulate in bulk material silos, mobile telephones, and radio devices, or interfering surge voltages caused by magnetic valves, contactors or frequency converters.
SICK also recently launched CM 18 PTFE sensor (Polytetrafluorethylene), which is specially designed for regulating the filling levels of acids, alkalis or solvents, as well as checking presence in areas with aggressive steams and vapors.
