Gavazzi Photo Electric M18 switches ~ PA series

Carlo Gavazzi PA 18 Series Photo Electrics

A cost- saving solution perfectly tailored to automation applications, ensuring maximum precision in object detection.
Lainate, March 2011 – Carlo Gavazzi Automation – the international electronics Group with activities in the design, manufacture and marketing of electronic equipment, launches PA18, the new range of M18 Powerful Photoelectric Sensors.
The PA18 is a new series of cost-effective sensors perfectly tailored to automation applications with a good price/performance ratio. Offered in a compact M18 threaded ABS housing, this new sensor series is a space saving solution, available in both axial (straight) and radial (90° rightangled)versions. The PA18 is fitted with a new smart, cost saving accessory which allows quick and easy wall mounting and setup from 1 to 4.5mm. Thanks to the built-in microprocessor, the new M18 powerful photoelectric sensors guarantee advanced filtering and detection, ensuring secure and flexible customized solutions. This sensor has been designed in order to avoid false detection caused by lighting or electromagnetic interference, thus reducing system maintenance while increasing application uptime. Furthermore, due to the efficient aspherical lens design, the PA18 sensors benefit from a longer sensing distance as well as high-speed detection.
These new devices are distinguished by their reliability under the harshest cleaning conditions. The PA18 range can resist water pressure up to 100 bar and cleaning agents and disinfectants, complying with the requirements set out by ECOLAB, IP67, IP69K.
“The launch of this new family of photoelectric sensors is very important for Carlo Gavazzi and allows us to stay competitive in the Material Handling, Packaging, Textile and Food & Beverage markets”, says Torben Rochat – International Product Manager. “Our intention is to offer our customers a more powerful product range and, for this reason, we have concentrated our efforts on the update of the M18 sensors.
We are confident that the PA18 series will be warmly welcomed on the market and will help us to extend our business”.
The PA18 range is developed by Carlo Gavazzi’s unit in Denmark and has a very precise and linear sensitivity adjustment which, through a manual potentiometer, allows accurate and easy setting from close distances to full range.
