CA18CAN12BPA2IO

## **CA18CAxxBPxIO - IO-Link** 

## **Capacitive Proximity Sensors with IO-Link communication** 

## **Benefits** 

- **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:** 4[th] Generation TRIPLESHIELD[TM] 

- **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. 

## **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 4[th] Generation of TRIPLESHIELD[TM] technology providing increased immunity to electromagnetic interference (EMI), especially to frequency drives, and improve the immunity to humidity and dust. 

- **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. 

- 

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. 

## **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.

## **Main functions** 

- The sensor can be operated in IO-Link mode once connected to an IO-Link master or in standard I/O mode. 

- Adjustable parameters via IO-Link interface: 

   - Sensing distance and hysteresis. 

   - 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.
