## **Product Descri tion p** 

The CA18CA.. capacitive proximity switches feature an improved 4[TH] Generation _TRIPLESHIELD_[TM] technology. Furthermore, these sensors feature increased immunity to electromagnetic interference (EMI), especially to frequency drives. Not only does 4[TH] Generation _TRIPLESHIELD_[TM] feature an increased EMI, but  it also increases the immunity to humidity and dust. The implementation of stability indication eases the setup procedure as both Stable ON and Stable OFF positions are 

indicated by the green and yellow LEDs. The sensing distance is increased by 25 % allowing room for additional stable detection. 

The Dust Alarm function gives an early warning that the sensing surroundings have to be cleaned. The Temperature alarm function raises an alarm if the sensing surface goes beyond 60 degree Celcius. The sensor housing is featuring IP69K as well as approval by ECOLAB for cleaningand disinfection agents.

* For Flush type sensor flush mounted in conductive material, the usable operating distance (Su) is 0.80 x Sr ≤ Su ≤ 1.2 x Sr for temperatures exceeding 0 - 60 °C ( 32 - 140°F). 

** The IP69K test according to DIN 40050-9 for high-pressure, 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.

## **Adjustment Guide** 

The environments in which capacitive sensors are installed can often be unstable as regards temperature, humidity, object distance and industrial (noise) interference. That is why Carlo Gavazzi offers as standard features in 

all TRIPLESHIELD[TM] capacitive sensors a user-friendly sensitivity adjustment instead of a fixed sensing range. Likewise, these sensors provide an extended sensing range to accommodate mechanically demanding areas and tem- 

perature stability to ensure high immunity to electromagnetic interference (EMI) and a minimum need for adjusting sensitivity, if the  temperature varies.
