Product No: SMT-UZ11
This IEC 62368-1 UL 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 62368-1 UL Unjointed Finger Probe (compliant with IEC 61032 Test Probe 1)
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:
1. Inspect the probe for damage (e.g., bent stainless steel finger, cracked nylon handle).
2. Power on the electronic device and allow it to reach normal operating mode.
3. Hold the handle and align the unjointed finger with the device’s potential access points (e.g., vents, port gaps).
4. Apply steady 10N thrust to the finger toward internal hazardous parts.
5. Check if the finger touches any dangerous components (e.g., live wires, moving parts).
6. Record whether the device meets safety requirements (pass/fail).
Applications:
1. Safety testing of audio/video devices (e.g., smart TVs, wireless speakers) per IEC 62368-1:2022 Figure 5.3-1.
2. Compliance checks for IT equipment (e.g., laptops, Wi-Fi routers) to block finger access to hazards (UL 62368-1:2023).
3. Verification of office electronic devices (e.g., laser printers, desktop scanners) per IEC 61032:2021 Figure 1.
4. Quality control for portable electronics (e.g., tablets, e-readers) during manufacturing for global markets.
5. Post-production safety audits of gaming consoles to ensure compliance with IEC/UL standards.
