1. Highly Sensitive Detection
Can detect foreign objects such as iron, stainless steel, and non-ferrous metals.
Advanced digital signal processing technology ensures detection accuracy and stability.
2. Sturdy and Durable Construction
The frame is constructed of welded stainless steel, offering excellent vibration and interference resistance.
Suitable for long-term, continuous operation.
3. Heavy-Duty Conveyor System
Equipped with a high-load-bearing belt conveyor, it can handle products weighing 1-50 kg.
Adjustable conveyor speed to match the cycle time of automated production lines.
4. Intelligent Human-Machine Interface
User-friendly touchscreen operation allows for easy parameter settings.
Automatically records inspection data and can be connected to the factory's MES system or printer.
5. Multiple Rejection Methods
Configurable rejection methods include pusher, lift gate, air blower, and alarm shutdown, depending on product type.
An alarm shutdown function is available for overweight or fragile products to prevent secondary damage.
