Sensors made flush for food
February 2003
Sensors & Transducers
Six new flush-mountable inductive proximity sensors with M12 and M18 bodies, which are specifically designed to withstand the rigours of food-industry applications, are among the latest additions to IFM Electronic's Efector M range. Also new and suitable for food industry use are Efector M sensors with M30 bodies, which are available in both flush-mounting and non-flush mounting versions.
All of the new sensors have corrosion-resistant stainless-steel bodies with food-friendly PEEK sensing faces. They offer an IP69K protection rating, making them suitable for use in even the most arduous environments, and they can operate continuously in ambient temperatures of up to 100°C without compromising performance or reliability. Full compatibility with CIP operations is assured.
The new sensors offer all of the established benefits of the Efector M range including stable operation, high reliability and extended sensing ranges compared with traditional sensors of the same body size. M12 flush-mountable models, for example, have a nominal sensing range of 3,5 mm, while the corresponding figures for M18 and M30 models are 5 mm and 12 mm respectively. M30 non-flush models have a nominal sensing range of 22 mm.
To ensure electrical compatibility with virtually every installation, the new sensors are offered as universal models that can be connected as three-wire PNP or two-wire PNP/NPN devices, and as economical three-wire PNP-only models. Outputs are fully protected against reverse polarity and overload.
For ease of adjustment, the Efector M sensors are equipped with a set-up LED that confirms when the target is within the reliable sensing range, and a status LED that provides instant visual confirmation of the output state. Connections to the sensors are made with industry standard M12 connectors, and the contact pins within the sensors themselves are gold-plated to ensure maximum reliability.
