IEC 62368-1 Figure V.1 UL Unjointed Finger Probe

IEC 62368-1 Figure V.1 Unjointed Finger Probe is a specialized safety tool built for testing audio/video, IT, and similar electronic devices. It features a rigid, unjointed stainless steel “finger” that mimics human finger access—critical for verifying if hazardous live or mechanical parts remain out of reach. Paired with an insulating nylon handle for safe, non-slip operation, it applies a precise 10N thrust to match real-world accidental contact. Strictly aligned with IEC 62368-1 and UL standards, it’s durable, easy to maneuver, and essential for manufacturers to ensure device compliance and prevent end-user electric shock or mechanical injuries.

Specifications:
• Probe Type: IEC 62368-1Figure V.1 Unjointed Finger Probe.
• Finger Material: Stainless steel (rigid, corrosion-resistant, maintains dimensional accuracy)
• Handle Material: Nylon (insulating, heat-resistant, non-slip for secure grip)
• Key Dimensions:
– Finger Diameter: 12 mm ± 0.1 mm
– Effective Finger Length: 80 mm ± 0.2 mm
– Total Length (Finger + Handle): 180 mm ± 0.5 mm
• Applied Thrust:10N ± 0.5N (precise force to simulate accidental human contact)
• Core Function: Verifies inaccessibility of hazardous live/mechanical parts in audio/video, IT, and similar electronic devices

Test Procedures:
• Inspect the probe for damage (e.g., bent stainless steel finger, cracked nylon handle).
• Power on the electronic device and allow it to reach normal operating mode.
• Hold the handle and align the unjointed finger with the device’s potential access points (e.g., vents, port gaps).
• Apply steady 10N thrust to the finger toward internal hazardous parts.
• Check if the finger touches any dangerous components (e.g., live wires, moving parts).
• Record whether the device meets safety requirements (pass/fail).

Applications:
• Safety testing of audio/video devices (e.g., smart TVs, wireless speakers).
• Compliance checks for IT equipment (e.g., laptops, Wi-Fi routers) to block finger access to hazards.
• Verification of office electronic devices (e.g., laser printers, desktop scanners).
• Quality control for portable electronics (e.g., tablets, e-readers) during manufacturing for global markets.
• Post-production safety audits of gaming consoles to ensure compliance with IEC/UL standards.
