Pepperl+Fuchs has added new sensors to its ML4.2 family of precision sensors. Apart from IP67/69k protection, these sensors have scratch- and chemical-resistant lens, highly visible LEDs and a robust full-metal die cast insert for mounting. Among the other new additions are dual sensors with background suppression for applications such as web alignment and for improved detection of transparent media. Also added is the new F77series of ultrasonic sensors, a series of miniature cube sensors which are simple to use, and have a high sensing range of up to 400 mm and a small blind range. These features make the F77 series quite suitable in applications such as sheet presence detection and paper stack centring.
