Product Introduction
Zero Tolerance for Metal Contamination.
In the high-stakes garment industry, a single broken needle fragment can trigger costly recalls and destroy brand reputation. The KHN-808S Automatic Conveyor Needle Detector is engineered to eliminate this risk with military-grade precision. Unlike standard detectors that struggle with false alarms from buttons or zippers, the KHN-808S features a newly designed coil unit that minimizes the "Material Effect," ensuring you catch only the metal, not the fabric.
Whether you are producing high-end fashion or industrial workwear, the KHN-808S offers the perfect balance of speed (up to 25m/min) and sensitivity. It is not just a machine; it is your final line of defense in quality control.
Advanced Functions
1. Unrivaled Anti-Interference Technology
Most detectors fail when they encounter metallic accessories like zippers or sequins. The KHN-808S utilizes an upgraded coil unit that homogenizes the sensor's aperture. This significantly reduces the "Material Effect," allowing the machine to distinguish between harmless garment accessories and dangerous ferrous fragments.
2. Industry-Leading Speed & Efficiency
Time is money. With a conveyor speed of up to 25 meters per minute, the KHN-808S is one of the fastest in its class. The speed is fully adjustable, ensuring that even delicate items with various accessories pass through smoothly without jamming or false triggers.
3. Smart "Environment Checking Mode" (Patent Pending)
Factory floors are full of electromagnetic interference from other machines. Our unique Environment Checking Mode automatically scans the surrounding environment to ensure the machine is calibrated perfectly for the specific location, drastically reducing downtime and pre-checking time.
4. Fully Automated Self-Check System
Say goodbye to manual coil testing. The KHN-808S system automatically checks its own sensors upon startup. This ensures the machine is always ready to work and guarantees 100% detection reliability without the need for operators to check each coil one by one.
