The Carlo Gavazzi TRIPLESHIELD™ design, now in its 4th generation, continues a tradition of providing the best EMI immunity of any capacitive sensor on the market. In addition to improved compensation for dust and humidity, an optional Dust Alarm Output gives an early warning of accumulation on the face of the sensor. The CA30CA Series is designed for harsh environments, providing IP67 and IP69K protection, ECOLAB approval for chemical resistance, and rated to withstand temperatures up to 248║F (120░C) on the sensing face. An optional Temperature Alarm Output warns the user if the sensing face surface exceeds 140║F (60░C).


Technical specifications include

Sensing distance: 2-20mm flush or 4-30mm non-flush
10-40VDC, NO & NC, NPN or PNP, 200mA transistor outputs
IP67, IP69K; NEMA 1, 2, 4, 4X, 5, 6, 6P, 12
Laser engraved labeling withstands IP69K cleaning
Dust and humidity compensation
Increased temperature stability
Optional Dust Alarm or Temperature Alarm output
Two diagnostic LEDs (green and yellow)

TRIPLESHIELDTM exceeds most standard norms:

Electrostatic discharge (EN61000-4-2): >40kV
Electrical burst transients (EN61000-4-4): ▒4kV
Surge (with 500 O) (EN61000-4-5): >2kV
Wire conducted disturbance (EN61000-4-6): >20Vrms
Power-frequency magnetic fields (EN61000-4-8)
- Continuous, 75.9ÁTesla: >60A/m
- Short-time, 759ÁTesla: >600A/m
Radiated, RF, E-M fields (EN61000-4-3): >20V/m

The new CA30CA Series Capacitive Proximity Sensors are available in a vast range of configurations, and are ideal in a numerous applications and industries, including: plastics, agriculture, pellet burning stoves, packaging, material handling, and food and beverage.

CA30CA TRIPLESHIELD™ Sensors are cULus and ECOLAB approved, CE marked. For more information on these sensors, please click on any of the links below:
