Product Overview


The 220V Leather Non Power Needle Detector represents a unique hybrid solution for leather product manufacturers requiring metal contamination inspection without continuous power operation. This innovative detector combines a primary passive magnetic induction system – operating entirely without electricity – with an optional 220V-powered alarm enhancement module for facilities requiring audible alerts .


Designed specifically for leather and leatherette materials, this detector features a 450mm × 300mm inspection surface optimized for detecting ferrous contaminants as small as 0.8mm in diameter in leather products. The non-powered core system uses strategically arranged permanent neodymium magnets to create a uniform magnetic field, making it ideal for environments where electrical access is limited or wet cleaning processes create hazards .


Constructed with a rust-resistant aluminum frame and scratch-resistant inspection plate, the detector safely handles leather materials without causing surface damage. When connected to power, the optional module adds LED indicators and an 85dB alarm, providing flexible operation across different production environments.


Product Features


Dual-Operation Modes

Primary non-powered detection mode using permanent magnets for electricity-free operation, with optional 220V-powered alarm mode adding audio-visual alerts when power is available.

Leather-Safe Design

The inspection surface features a smooth, polished acrylic plate specifically designed to prevent scratches or marking on finished leather products during inspection.

High-Sensitivity Passive Detection

Permanent neodymium magnet array creates a magnetic field sensitive enough to detect 0.8mm diameter ferrous particles without electrical amplification, ensuring reliable detection in non-powered mode .

Compact, Portable Construction

Lightweight 12kg design with integrated carry handles allows easy relocation between workstations, with non-slip rubber feet ensuring stability during use.

Mechanical Indicator System

In non-powered mode, a precision spring-loaded mechanical indicator provides clear visual confirmation of detected contaminants, with manual reset functionality.


Applications


Leather Goods Production

Essential for inspecting leather bags, wallets, and accessories where needles may break during stitching or assembly processes.

Footwear Manufacturing

Ideal for checking leather shoes and boots at various production stages, from cut leather pieces to finished products.

Upholstery Leather Inspection

Ensures leather used for furniture and automotive upholstery is free from metal contaminants that could damage equipment or cause injury.

Artisanal Leather Workshops

Perfect for small-batch producers and craft workshops where electrical access may be limited or mobility is prioritized.


FAQ


How does the non-powered detection work without electricity?

The detector uses a grid of high-strength neodymium magnets arranged in a specific pattern to create a uniform magnetic field. Ferrous contaminants passing through this field disrupt the magnetic flux, causing a lightweight metal indicator to move within view, providing a visual alert without any power source .

What advantages does the dual-mode operation offer?

In non-powered mode, it provides safe operation in wet environments or where electricity is unavailable. When connected to 220V power, the enhanced alarm system adds audible alerts and brighter indicators, improving detection awareness in noisy production environments.

Can it damage delicate leather finishes?

No, the inspection surface is constructed from scratch-resistant acrylic with a polished finish that won't mar or mark leather, even with repeated contact during inspection of high-end leather products.

How does it compare to fully electric leather detectors?

While it lacks some advanced features of full-electric models, it offers 90% of the detection capability at a lower price point, with the added benefits of portability and safe operation in environments where electricity is problematic.
