The P128 is manufactured by Roland Electronic, and is a single-sided double sheet detection of thick blanks. It covers thickness up to 12 mm, making it suitable for manufacturing of structural parts for trucks and in shipbuilding. To meet certain power requirements and measurement time, the sensor has been fully improved.
The sensor has a robust push-pull connector that can withstand long term use. The working range of the P128 is ferrous material from 1 mm to 12 mm single sheet thickness, and the measuring time (120%) is 450 ms to 1.15 s. It has an IP65 protection class. Dimension of the sensor in diameter is M128 x 1.5, and the sensor length without plug is 85 mm.
