IEC 61010-1:2021 Clause 6.2.3 4.0mm Hazardous Live Parts Probe

The IEC 61010-1:2021 Clause 6.2.3 4.0mm Hazardous Live Parts Probe is engineered for precision safety testing, targeting accessible hazardous live components in electrical, electronic, and medical devices, including laboratory analyzers, medical monitors, and industrial control panels. Featuring a 4mm-diameter conductive stainless steel probe, it accesses narrow gaps such as terminal slots and vent seams, which are unreachable by larger tools. The insulated, heat-resistant handle safeguards testers from electric shock. It delivers a controlled 1N thrust to simulate light accidental contact, ensuring adherence to international safety standards. This durable and reliable tool is essential for manufacturers to mitigate electric shock risks and validate product safety for global markets. NOTE: SMT-4001 is provided without cable. For testing with Low-voltage Test Supply, choose LISUN model SMT-529CV or opt for SMT-4001C with cables.

Specifications:

• Tool Type: 4.0mm Hazardous Live Parts Probe (for narrow-gap live-part accessibility testing)
• Probe Material: Stainless steel
• Handle Material: Nylon
• Key Dimensions: – Rod length: 100 mm – Rod diameter: 4 mm – Handle diameter: 10 mm – Handle length: 100 mm
• Applied Thrust: 1N ± 0.1N (simulates light accidental contact; standard for live-part accessibility testing)
• Core Function: Detects accessible hazardous live parts in narrow equipment gaps; verifies compliance with electric shock protection standards

Test Procedures:

1. Inspect the probe for damage (bent tip, cracked insulation, poor conductivity) and connect to a live-part detection instrument.
2. Power on the equipment under test (EUT) and set it to normal operating mode.
3. Hold the insulated handle and align the 4.0mm probe tip with narrow EUT gaps (e.g., terminal slots, vent seams).
4. Insert the probe into the gap with a steady 1N thrust—stop when resistance is felt or fully inserted.
5. Check the detection instrument for signals (indicating contact with live parts).
6. Record results: Pass if no contact; Fail if contact is detected.
