Detecting liquid levels in confined spaces in machines and facilities can pose problems. For these types of applications, Baumer developed its CFDK 25 capacitive sensor. The 52.4 x 25-mm flat housing design has a height of only 6 mm and has an available mounting frame. In addition to attachment with two screws, the frame allows installation with cable ties, a Velcro fastener or glue.
The capacitive sensor has four fixed nominal sensing distances from 2 to 15 mm offered in a chemical resistance housing made of Polyamid 12 plastic.

Print mark detection in high-speed packaging and printing operations requires a rapid response sensor. Baumer’s FKDK 14 diffuse contrast sensor uses a white LED to precisely detect print marks within a response time of 50 µs. With the white light source, the photoelectric sensor can reliably detect print marks of all colors, even with slight contrast to the background. A yellow LED visible through the sensor’s transparent housing base indicates the switching status.
The sensor’s 14.8 x 43 x 31-mm size allows easy integration into machines.

Sensors Detect Metal Targets In Extreme Heat & Cold
For sensing applications exposed to temperatures from -25 degrees C to +180 degrees C, Baumer has introduced the new IFRH Series of Inductive High Temperature Sensors, a family of two-part proximity switches available in M8, M12 and M18 designs with chromium nickel steel housings.
Intended for flush-face installation, the IP67-rated IFRH sensors are designed to detect the presence of metal targets. With an overall length of just 30 mm, the M8 sensor is specifically designed for use in limited-space applications. Depending upon the housing size, nominal switching distance ranges from 1.5 mm to 5 mm.
An FEP jacketed cable connects the sensor’s temperature-sensitive processing electronics to the sensor head, protecting the electronics from damage. The sensors offer an operating voltage range between 10…30 VDC. These sensors are appropriate for use in aerospace, automotive, marine, PCB fabrication, food and beverage processing, oil processing, laboratory automation, rubber and plastics fabrication, chemical processing, packaging, print/graphics, textile production, and water treatment applications.
Optical Sensor Accurately Detects Small, Fast-Moving Objects
For sensing applications involving distances as far as 200 mm, Baumer has introduced the new Long-Range ParCon, an analog optical line sensor that projects a continuous 24 mm wide beam of parallel light to a reflector, permitting extremely fast and reliable detection of moving parts as small as 0.5 mm. The sensor can also measure object widths regardless of the target’s position in the measuring field.
This cost-effective alternative to light curtain technology accurately detects and measures metallic and non-metallic objects at high speed processing rates up to 1 kHz with resolutions up to 0.1 mm. The Long-Range ParCon is designed to accurately detect material edges in applications such as packaging, textile manufacturing, paper production, and printing/graphics. This sensor can also be used in PCB manufacturing, food and beverage packaging, laboratory automation, medical device manufacturing and metalworking applications.
The sensor features a 24 mm wide parallel light beam that allows accurate detection and measurement of thick or thin objects regardless of their location within the sensing field. Sized at just 67 x 34 x 16.5 mm, the Long-Range ParCon’s housing contains the sender, receiver, and specialty optics. Only a reflector is needed to operate the sensor, which mounts quickly and easily into small space applications.
Non-Contact Photoelectric Level Sensors

Southington, Conn. – For a range of liquid level detection applications in laboratory automation, medical devices, pharmaceutical packaging, beverage processing and other industries, Baumer has introduced the FFDK 16 Photoelectric Level Sensors, compact sensors designed to be mounted onto transparent or half-transparent standpipes from 3 to 13 mm in diameter.

These easy to mount, non-contact sensors feature integrated electronics and require no adjustments to be made post-installation for accurate detection of fluid presence. A dark/light switch allows the user to select the appropriate setting for their specific application. These rugged sensors are made with PFI for chemical resistance.
Foam can cause measurement errors in standard optical level sensors. To prevent this problem, the optical version of the FFDK 16 sensor features fibers that are arranged in rows, which allow the sensor to suppress foam and air bubbles up to 3 mm in size.
