CA18CAxxBPxIO - IO-Link
Capacitive Proximity Sensors with IO-Link communication
Benefits
Description
The new generation of CA18CA…IO sensors are
a complete family of high performance capacitive
sensors for detection of most solid or liquid targets
in industrial applications such as Plastic & Rubber,
Agriculture, Food & Beverage and Material
handling. The 4th Generation of TRIPLESHIELDTM
technology providing increased immunity to
electromagnetic interference (EMI), especially to
frequency drives, and improve the immunity to
humidity and dust.
The sensor housing has the IP69K rating as
well as approval by ECOLAB for cleaning- and
disinfection agents.
On-board IO-Link communication opens up a
variety of functions, such as easy communication
and customization of advanced parameter settings.
• A complete family. Availability in M18 in a robust PBT
housing with an operation of 2-10 mm flush or 3-15 mm
non-flush.
• Enhanced EMC performance: 4th Generation
TRIPLESHIELDTM
• Easy customization to specific OEM requests:
different cable lengths and materials, special labeling,
customized pig-tail solutions with special cables and
connectors are possible on request.
• The output can be operated either as a switching output
or in IO-Link mode.
• Fully configurable via output IO-Link v 1.1. Electrical
outputs can be configured as PNP / NPN / Push-Pull /
External input, normally open or normally closed.
• Timer functions can be set, such as ON-delay, Offdelay, and one shuts.
• Logging functions: Temperatures, detecting counter,
power cycles and operating hours.
• Detection modes Single point, Two point and window
mode.
• Analogue output: In IO-Link mode the sensor
will generate 16 bit analogue process data output
representing the dielectric value measured by the sensor.
•
Applications
• Detection not only the level of plastic pellets in plastic molding machines but also the dielectric value of the pellets to
avoid false manufacturing.
• Detection of not only the wood pellets in pellets burners but also the density of the wood pellets.

►► Sensing modes: single point or two point or window mode.
►► Timer functions like: On-delay, Off delay, One shot leading edge or trailing edge.
►► Logic functions such as: AND, OR, X-OR and SR-FF.
►► External input.
►► Logging functions: Maximum temperatures, minimum temperatures, operating hours, operating
cycles, power cycles, minutes above maximum temperature, minutes below minimum temperature,
etc.

* The IP69K test according to DIN 40050-9 for highpressure, high-temperature wash-down applications.
The sensor must not only be dust tight (IP6X), but
also able to withstand high-pressure and steam
cleaning. The sensor is exposed to high pressure
water from a spray nozzle that is fed with 80°C water
at 8’000– 10’000 KPa (80–100bar) and a flow rate of
14–6L/min. The nozzle is held 100 –150 mm from the
sensor at angles of 0°, 30°, 60° and 90° for 30s each.
The test device sits on a turntable that rotates with
a speed of 5 times per minute. The sensor must not
suffer any damaging effects from the high pressure
water in appearance and function.
