The M18 and M30 ultrasonic sensors feature smooth transducer faces, short blind zones, adjustable sensing fields, and robust
chrome plated brass barrels, along with multiple options for outputs and configurations that enable users to select the best design
for their application.
Output configurations range from a single output with an adjustable set point to versions with configurable outputs either as dual set
point, analog, window, retroreflective, or IO-Link. Sensors can be taught via wire, integral buttons, or IO-Link.
Certain M18 and M30 versions are available with ATEX and IECEx approvals for environments that have dust or gases which could be
ignited and cause a fire or explosion.
The CK40 and CP40 rectangular ultrasonic sensor family uses separate transducers for the transmitter and receiver, giving these
sensors a 60° sonic cone angle for detecting targets, which is much larger than what is possible with the M18 or M30 barrels.
Performance Curves
The diagrams show the detection ranges of the individual ultrasonic sensors, covering ranges of 40 to 600 cm. Different targets are used
in sizes 20 x 20 mm, and 100 x 100 mm according to the EN standard 60947-5-2, as well as a round rod with a diameter of 27 mm in order
to compare the detection ranges of different ultrasonic sensors. When using other targets than the standard ones, the detection ranges
may vary due to different reflection properties and geometries.
