IEC 62368-1 Figure V.5 Terminal Test Probe

IEC 62368-1 Figure V.5 Terminal Test Probe is a precision safety compliance instrument engineered for verifying hazardous live part inaccessibility in audio/video (AV) and information/communication technology (ICT) equipment. This probe specifically targets micro-terminals, miniature connectors, and ultra-narrow apertures requiring dimensional accuracy per IEC 62368-1 and UL 62368-1 standards.

The probe features an ultra-thin, rigid stainless steel tip with 1.0 mm ± 0.05 mm diameter to access compact spaces without component damage, paired with an insulating nylon handle for operator safety during controlled testing procedures. Engineered to simulate accidental contact with small terminals, this probe verifies that hazardous live parts remain inaccessible, ensuring strict compliance with IEC 62368-1 safety requirements.

Constructed with durable, dimensionally stable materials, this terminal test probe is essential for manufacturers, testing laboratories, and quality control departments conducting detailed AV/ICT equipment safety compliance assessments.

Technical Specifications

• Probe Type: IEC 62368-1 Figure V.5 Terminal Test Probe
• Probe Material: Stainless steel (ultra-thin, rigid, corrosion-resistant; maintains 1.0 mm diameter accuracy)
• Handle Material: Nylon (insulating, non-slip, heat-resistant; ensures secure grip during precise operation)
• Key Dimensions:
  • Probe Diameter: 1.0 mm ± 0.05 mm
  • Effective Probe Length: 20 mm ± 0.2 mm (optimized for micro-terminal testing)
  • Handle Length: 110 mm ± 0.5 mm
  • Total Length: 130 mm ± 0.5 mm
• Applied Force: No appreciable force (simulates light, accidental contact with micro-terminals/connectors)
• Core Function: Verifies inaccessibility of hazardous live parts in micro-terminals or ultra-narrow openings of AV/ICT equipment per IEC/UL 62368-1 test procedures

Test Procedures

1. Inspect the probe for damage (e.g., bent tip, cracked handle) to ensure dimensional accuracy.
2. Power on the AV/ICT equipment and allow it to reach normal operating mode.
3. Hold the nylon handle and align the 1.0 mm probe tip with the target micro-terminal or narrow opening.
4. Gently insert the probe (up to 20 mm effective length) toward potential hazardous live parts.
5. Check if the probe contacts any dangerous components (e.g., exposed terminal contacts).
6. Record whether the equipment meets safety requirements (pass/fail).
