4th Generation Tripleshield™ Capacitive Proximity Sensors

Carlo Gavazzi recently announced the expansion of their new 4th Generation Tripleshield™ CA18CA Capacitive Proximity Sensors with the addition of the new M18 CA18CA Series.  In addition to greatly improved immunity to dust, humidity, and electromagnetic interference (EMI), the CA18CA Series includes diagnostic alarms and two LEDs for better reliability and simplified troubleshooting during installation.

Marshall Wolf Automation, your full line industrial automation distributor, is an authorized distributor for Carlo Gavazzi.

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 CA18CA 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.

The CA18CA Series Capacitive Proximity Sensors are available in a vast  range of configurations, and are ideal in a variety of applications and industries, including:  plastics, agriculture, pellet burning stoves, packaging, material handling, and food and beverage.

Who Made The World's First Proximity Sensor?

That would be Pepperl+Fuchs! They developed the world's first proximity sensor in 1958.

Pepperl+Fuchs continues to be an industry leader in industrial sensors. They offer a complete range of inductive, capacitive, photoelectric and ultrasonic sensors as well as identification systems, barcode and camera systems, rotary encoders, position measurement systems, cordsets, and other accessories.

Pepperl+Fuchs have achieved ISO 9001:2008 and ISO 14001:2004 certifications.

Marshall Wolf Automation has been a long-time authorized Pepperl+Fuchs distributor.

Carlo Gavazzi ICB Sensors Are Eco-Friendly Too!

The Carlo Gavazzi ICB Series is a new generation of eco-friendly inductive proximity sensors that feature a high performance potting material that is made from recycled corn by-product!  The new potting material provides an
eco-friendly design and high performance.  This thermoplastic hotmelt filling is made from recycled corn by-product
and allows:
- Reduced impact on the environment
- Higher resistance to mechanical stress and vibrations
- No risk of breaking electronic components

- Increased reliability and improved stability
- Longer sensor lifetime

Inductive proximity sensors provide a reliable and cost effective solution for many applications in machinery and
automation equipment. These robust sensors detect metal objects without physical contact, giving a wear-free solution
in harsh environments.  What sets the Carlo Gavazzi ICB series apart is their onboard microprocessor that takes them into the world of digital technology, merging the benefits of sensing and data transmission.

• The new range includes:
- M12, M18 and M30 long or short barrel housings
- Sensing range from 2mm up to 22mm

• All sensors come with:
- Rugged nickel plated brass construction
- LED output state indicator
- Short circuit, reverse polarity and transients protection

Through Beam Photoelectric Sensors 101

Through beam mode is a popular type of photoelectric sensor that uses two separate housings.

One is the transmitter, or emitter, that sends the light beam out. The other is the receiver and, yes, it receives the light beam!

When the target 'breaks' the light beam, the output from the receiver is sent. This is a very efficient sensing mode and allows for the longest photoelectric sensing range.

Marshall Wolf Automation is your authorized distributor for all the top brands of thru-beam photoelectric sensors. Pepperl+Fuchs, Idec, Takex, Carlo Gavazzi, Autonics, Baumer... you name it, we can get it.

Capacitive Proximity Sensor Question


I need a capacitive proximity (18mm) ac120v and I need this proximity to drop out a relay when product is sensed. Would like to use the proximity to drive an Idec RSSAN-25 relay. I didn't see how many amps of load the proximity could handle. If this will work I will need 2 proximity sensors and 2 relays.


CR18-8AC Autonics Capacitive Proximity Switch 18 mm diameter, 90-250 vac input. This unit will give you an 8 mm sensing distance and 200 mA of ac current to fire the relay.

RSSAN-25A Idec 25 amp solid state relay. (20mA needed to fire AC coil).
