IEC 61032 Figure 4 Steel Wire with 1N Dynamometer

Specifications:
Tool Type: IEC 61032 1mm Steel Wire with 1N Dynamometer, IP4X Test Probe D
Steel Wire Material: Conductive stainless steel (resistance ≤ 0.1Ω; corrosion-resistant; diameter tolerance: ±0.02mm)
Dynamometer Integrated: 1N capacity; accuracy: ±0.05N; digital display (optional) for real-time force monitoring
Key Dimensions:
– Wire length: 100 mm
– Wire diameter: 1.0 mm
– Circular-baffle diameter: 35 mm
– Handle diameter: 10 mm
– Handle length: 100 mm
– According to IEC61032 figure 4 (the Test probe D).
– Thrust: 1N
Applied Force: Fixed 1N (controlled by dynamometer; prevents over-force on delicate components)
Core Function: Navigates ultra-narrow device gaps via 1mm wire; detects hazardous live parts with precise 1N force; ensures IEC 61032 compliance

Test Procedures:
1. Inspect the steel wire for kinks, corrosion, or breaks; calibrate the dynamometer to confirm 1N accuracy.
2. Power on the miniaturized device under test (EUT, e.g., earbud charger) and set it to active mode (e.g., charging).
3. Hold the grip, align the 1mm wire tip with the ultra-narrow gap (e.g., charger port crevice).
4. Advance the wire into the gap, using the dynamometer to maintain exactly 1N force.
5. Check the connected live-part detector for signals (indicating contact with hazardous parts).
6. Record results: Pass if no contact; Fail if live parts are accessible.

Applications:
1. Testing ultra-narrow charging port gaps in wireless earbuds (per IEC 61032 Figure 4) to block circuit access.
2. Quality control for micro-LED display driver board gaps during manufacturing, ensuring IEC compliance.
3. Post-production testing of portable Bluetooth microphone USB-C port seams to meet global safety standards.
