## **Capacitive Proximity Sensor** 4[th] Generation of _TRIPLESHIELD_[TM] **CA18CBxxBPxIO** 

- LED bar graph for output, signal stability, power ON and easy adjustment 

- Available in M18 in a robust PBT housing, flush or non-flush and IO-Link 

- Sensing range: 2…10 mm flush or 3…15 mm non-flush 

- Sensitivity adjustment either by trimmer, teach-by-wire or by IO-link parameter 

- Supply voltage: 10 to 40 VDC 

- Output: PNP / NPN / Push-Pull / External input 

- Make and break switching function 

- Protection: reverse polarity, short circuit and transients 

- Cable and plug versions 

- Excellent EMC performance (4[th] generation _TRIPLESHIELD_[TM] ) 

## **Description** 

## **Part selection key** 

The new generation of CA18CB…IO sensors is 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 Materials handling. 

The sensor housing has the IP69K rating as well as approval by ECOLAB for cleaning and disinfection agents. 

The sensor has a LED bar 

graph that visualizes the signal stability and makes adjustment easy. 

The 4[th] Generation of _TRIPLESHIELD_[TM] technology provides increased immunity to electromagnetic interference (EMI), especially to frequency drives, and improves immunity to humidity and dust. 

The on-board IO-Link communication opens up a variety of functions, such as easy communication and customization of advanced parameter settings.
