HASHIMA HN-2880CS / HN-2790GS DUAL-HEAD NEEDLE DETECTORS

Hashima’s next-generation dual-head needle detector series—the HN-2880CS and HN-2790GS—features a design with two sensor arrays arranged in series. This configuration doubles scanning capability, eliminates blind spots, and ensures maximum reliability for export-oriented garment factories.

ADVANTAGES AND OUTSTANDING TECHNOLOGIES OF THE HASHIMA HN-2880CS / HN-2790GS

1. Dual-head design – Doubled safety, zero blind spots

Unlike traditional single-head models, the HN-2880CS and HN-2790GS feature two independent magnetic sensor arrays positioned sequentially along the conveyor belt. Products passing through are continuously scanned twice from different magnetic angles, ensuring the detection of broken needle fragments regardless of orientation—whether horizontal, vertical, diagonal, or deeply embedded within thick fabric folds or foam padding.

2. Dual-mode technology: Standard Mode & proprietary AP Mode

·       Standard Mode: Incorporates a new electromagnetic noise-cancellation system that minimizes interference from the factory environment (such as noise from nearby machinery, inverters, or motors), ensuring stable operation at high sensitivity.

·       AP Mode (Accessories Pass-through Mode): Hashima’s proprietary technology allows garments with compliant metal accessories (such as non-magnetic metal buttons or non-ferrous zippers) to pass through without triggering false alarms. This maintains continuous inspection productivity while preserving high sensitivity for broken needle detection.

3. Conveyor speed of 40 m/min – Industry-leading speed

·       Despite being a large dual-sensor system, the machine is equipped with a high-speed conveyor drive capable of speeds ranging from 15 to 40 m/min.

·       High-speed operation enables factories to process large volumes of finished goods daily and shorten packaging and shipping times without the risk of production line bottlenecks.

4. Superior inspection sensitivity: Fe Ø0.8 mm

With a standard aperture height of 120 mm, the machine achieves exceptional sensitivity, capable of detecting steel particles as small as Fe Ø0.8 mm. •     Factory-configurable detection heights—140 mm (Fe Ø1.0 mm), 160 mm (Fe Ø1.2 mm), and 180 mm (Fe Ø1.5 mm)—accommodate a wide range of products, from lightweight fashion items to thick puffer jackets, down coats, and bedding.

5. 7-inch Color LCD Touchscreen & Broken Needle Position Indicator

·       The 7-inch LCD touchscreen provides a clear, intuitive display of parameters for both detection heads, pass/fail counts, conveyor speed, and alarm history.

·       The detection heads utilize segmented sensor coils; upon detecting a foreign object, an LED indicator (Detection Position Lamp) identifies whether the broken needle is located on the left, center, or right side of the product, enabling QC staff to quickly locate and address the issue.

6. Time Savings with Auto PreChecker®

·       Simplifies the start-of-shift inspection process using an automatic calibration bar (PreCheck Bar).

·       Sensitivity across all sensors on both detection heads is verified fully automatically in a single pass, eliminating the need for a technician to manually scan specific points with a test piece.

·       Supports data output to a dedicated Citizen thermal printer (optional) for record-keeping of calibration logs. 

SMART UPGRADE & EXPANSION CAPABILITIES

·       Integrated RFID Reader (HRF-CR2 Series): Easily integrates with a dedicated RFID reader to simultaneously perform needle detection and accurate product counting, alert for missing tags, and export CSV reports for digital inventory management.

·       HN-C1 Digital Inspection Service: The HN-2880CS model is fully compatible with Hashima’s specialized HN-C1 inspection device; it performs detailed checks across 125 sensing points and issues an authentic electronic inspection certificate via a cloud-stored QR code.

COMPARISON: HASHIMA HN-2880CS VS. HN-2790GS

The primary difference between the two two-head needle detectors, HN-2880CS and HN-2790GS, lies in the factory option availability for sensor height and support for advanced digital inspection systems:

REASONS TO CHOOSE EACH MODEL

1. Why Choose HASHIMA HN-2880CS (Flagship / Versatile Solution)

• Varied product lines and thick/bulky items: Ideal for garment factories manufacturing winter coats, puffer down jackets, blankets, pillows, bedding, or padded workwear that require customized higher clearances such as 140 mm, 160 mm, or 180 mm.
• Strict buyer compliance and digital audit readiness: With support for Hashima's HN-C1 inspection service, facilities can undergo 125-point automatic sensor audits and obtain cloud-stored electronic test certificates with QR codes for international buyers and QA audits.

• Future-proof investment: Best for manufacturers looking for maximum flexibility and readiness for smart factory quality assurance workflows.

2. Why Choose HASHIMA HN-2790GS (Standard / Cost-Effective Solution)

• Dedicated production of light-to-medium garments: Best suited for lines focusing on shirts, trousers, T-shirts, underwear, swimwear, babywear, and sportswear where product thickness consistently clears the standard 120 mm tunnel height.
• Dual-head security with an optimized budget: Delivers the exact same dual-sensor protection (zero blind spots), 40 m/min conveyor speed, false-alarm reduction via AP Mode, and Fe Ø0.8 mm sensitivity, but offers a more economical capital investment compared to the CS model.
