Functions

“Factor 1” technology – detects all metals (iron, aluminum, copper, stainless steel) with less than ±10% sensitivity difference.

High magnetic field resistance (100 mT) – suitable for use near motors, transformers, or welding equipment.

High operational stability – ASIC technology minimizes temperature and voltage influence on accuracy.

Fast response – ideal for dynamic control systems.

Applications

Home user: For small automation projects or home workshops.

Engineer: For industrial equipment, production lines, testing stations, and robotics systems.

Electrician: Easy installation in systems; reliable for modernization and maintenance tasks.

Others: Suitable for CNC machines, packaging lines, conveyor systems, and alarms.
