• Cable and M12 connector versions available Product Description The CA18CA.. capacitive proximity switches feature an improved 4 TH Genera - tion TRIPLESHIELDTM tech - nology. Furthermore, these sensors feature increased immunity to electromagnetic interference (EMI), especial - ly to frequency drives. Not only does 4 TH Generation TRIPLESHIELDTM feature an increased EMI, but it also increases the immuni - ty 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 func- tion raises an alarm if the sensing surface goes beyond 60 degree Celcius. The sensor housing is featur- ing IP69K as well as approval by ECOLAB for cleaning- and disinfection agents.

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 appear - ance and function. 90° 60° 30° * 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).

Specifications are subject to change without notice (10.12.2020) 3 The environments in which capacitive sensors are installed can often be unsta - ble as regards temperature, humidity, object distance and industrial (noise) interference. That is why Carlo Gavazzi offers as standard features in all TRIPLESHIELD TM capac - itive sensors a user-friendly sensitivity adjustment instead of a fixed sensing range. Like- wise, these sensors provide an extended sensing range to accommodate mechanically demanding areas and tem - perature stability to ensure high immunity to electromag- netic interference (EMI) and a minimum need for adjusting sensitivity, if the temperature varies. Note: The sensors are factory set (default) to nominal sensing range Sn.Sn.

Specifications are subject to change without notice (10.12.2020) 5 Installation Hints Capacitive sensors have a unique ability to detect al- most any material in li quid or solid form. Capa ci tive sen - sors are able to detect me- tallic as well as non-metallic ob jects. How ever, their tradi- tional use is for non-metallic materials such as:

• Plastics Industry Resins, regrinds or mould- ed products.
• Chemical Industry Cleansers, fertilizers, liq - uid soaps, corrosives and pe t ro chemicals.
• Wood Industry Saw dust, paper products, door and window frames.
• Ceramics & Glass Industry Raw materials, clay or finish ed products, bottles.
• Packaging Industry Package inspection for lev- el or contents, dry goods, fruits and vegetables, dairy products. Materials are detected due to their dielectric constant. The bigger the size of an object, the higher the density of ma- terial, the better or easier it is to detect the object. The nominal sensing di stan- ce for a capaci tive sensor is refe r red to a grounded me tal plate (ST37).
