SC-F2B IEC 61032 Figure 2 Test Probe B
Product overview
The IEC 61032 Figure 2 Test Probe B (Jointed Test Finger) is a precision safety tool designed to simulate human finger movement for testing access to hazardous live parts in electrical/electronic equipment—from household appliances to industrial control panels. Its dual-jointed design bends 90° (±10°) in the same plane and direction, mimicking natural finger flexibility to navigate gaps rigid probes can’t reach. A 50 mm diameter baffle plate prevents over-insertion, while the 12 mm knurled metal tip detects live components. Crafted from conductive stainless steel (for durability/conductivity) and paired with an insulated handle, it applies gentle 10 N thrust—critical for validating safety and meeting global accessibility standards.

Test procedure
- Inspect the probe for loose joints, bent tips, or cracked insulation; confirm conductivity with a test tool.
- Power on the equipment under test (EUT) and set it to normal operating mode.
- Hold the insulated handle, use the joints to guide the 12 mm tip into EUT gaps (vents, panel seams, control slots).
- Apply steady 10 N thrust—stop if the 50 mm baffle touches the EUT or resistance blocks insertion.
- Check the connected live-part detector for signals (indicating contact with hazardous parts).
- Record results: Pass if no contact; Fail if the probe reaches dangerous components.
Applications
- Testing access to live wiring in household refrigerators (per IEC 61032:2017 Figure 2) to prevent electric shock.
- Verifying control panel gaps in office printers to block finger contact with circuits.
- Safety checks for industrial control box seams to avoid exposure to high-voltage terminals.
- Quality control for electric washing machines during manufacturing, ensuring UL 60335-1:2023 compliance.
- Post-production testing of small medical devices (e.g., blood pressure monitors) to validate hazardous part accessibility.
