Compact Photoelectric Sensors integrate background suppression.

Press Release Summary:

Supplied in PA18 and PH18 housings, background suppression (BGS) photoelectric sensors operate from -25 to +60°C, have spherical lens design that lends to 200 mm sensing distance range, and are designed to avoid any false detection caused by lighting or EMI. Detection is based on Active Pixel Sensor (APS) CMOS array comprising 64 x 1 sensors; each pixel represents specific position of detected object, offering accurate sensing distance regardless of object color.

Original Press Release:

Compact Photoelectric Sensors with Background Suppression

Buffalo Grove, IL – Carlo Gavazzi is proud to announce the launch of a new range of Background Suppression (BGS) Photoelectric Sensors in their popular PA18 and PH18 housings. This allows for precise distance detection and a fine distinction between a target and its background, with the flexibility of an industry standard housing.

The detection principle is based on an Active Pixel Sensor (APS) CMOS array consisting of 64 x 1 sensors, where each pixel represents a specific position of the detected object. This offers an accurate sensing distance regardless of object color, allowing the sensor to be used on a variety of applications. These sensors have also been designed to avoid any false detection caused by lighting or electromagnetic interference, thus reducing system maintenance and increasing the application up-time. Furthermore, thanks to the efficient spherical lens design, this range has a longer sensing distance compared to the other background suppression sensors available on the market today.

The PA18 and PH18 sensors can withstand water pressure up to 100 bar, cleaning agents, and disinfectants. They comply with all of the requirements for the ECOLAB and IP68/69K wash-down approvals. The sensors are well suited for applications in packaging, material handling, and food & beverage.

Technical specifications include:

• Sensing range: 200 mm

• Power supply: 10 to 30 VDC

• Output current rating: 100 mA; Output voltage drop: 2.0 VDC @ 100mA

• Two outputs -Normally Open NO, Normally Closed NC, available for NPN or PNP outputs

• Short-circuit, reverse polarity and overload protection

• Temperature range: -25°C to +60°C

• IP67, IP69K

• ECOLAB approved, CE-marked and cULus approved according to UL508

The PA18CAB… and PH18CNB… sensors are available from Carlo Gavazzi’s North American network of sales offices and distributors, or at
