ON-688CD6S / ON-688CDD6S is a digital conveyor needle detector designed for pre-shipment inspection of garments and textile products. It detects broken sewing needles and other ferrous metal contaminants before products enter packing or shipment, making it suitable for export garment inspection, brand quality control and high-volume production environments.

Compared with handheld needle detection, the conveyor system allows garments and textile products to pass continuously through the detection area. A 10-point sensor probe system provides three ferrous detection modes of ΦFe 0.8 / 1.0 / 1.2 mm, with 12-level sensitivity adjustment according to product and inspection requirements.

When metal contamination is detected, the machine can trigger an electronic alarm and stop or reverse the conveyor. Built-in pass, reject and total counters help record inspection results, while the touchscreen interface and multilingual display support daily production use. Automatic calibration every two hours helps maintain inspection consistency during longer operating periods.

ON-688CD6S uses a single detection tower with printer, while ON-688CDD6S uses dual detection towers with printer for production requiring an additional detection stage.
