Test Probe 13 of IEC 61032 – Short Test Pin

The Test Probe 13 of IEC 61032 (Short Test Pin) is a precision safety tool designed for small, compact electrical/electronic devices—such as wireless earbud charging cases, smartwatch ports, and mini medical sensors. Its short, rigid conductive tip (optimized for ultra-narrow openings) targets gaps too small for standard probes, testing if hazardous live parts (e.g., tiny circuit terminals, charging pins) are accessible. Paired with a lightweight insulated handle for precise control, it applies a gentle 1N thrust to mimic accidental light contact. Strictly compliant with IEC 61032, it’s durable, accurate, and essential for manufacturers to eliminate electric shock risks in miniaturized devices.

NOTE: Please note SMT-1213 is without cable. If you want to test with Low-voltage Test Supply LISUN model is SMT-529CV, you may choose SMT-1213C with cables. 

Specifications:

Core Function: Detects accessible hazardous live parts in ultra-narrow openings of small devices; ensures IEC 61032 compliance

Test Procedures:
1. Inspect the probe for damage (bent tip, cracked insulation) and confirm conductivity with a test tool.
2. Power on the small device under test (e.g., earbud charger) and set it to active mode (e.g., charging).
3. Hold the insulated handle and align the 2mm tip with ultra-narrow gaps (e.g., charger port seams, button crevices).
4. Insert the probe into the gap with a steady 1N thrust—stop at resistance or full tip insertion.
5. Check the connected live-part detector for signals (indicating contact with hazardous parts).
6. Record results: Pass if no contact; Fail if live parts are accessible.

Applications:
1. Testing ultra-narrow port gaps in wireless earbud charging cases (per IEC 61032:2017 Figure 5.13) to block circuit access.
2. Verifying button crevices in portable glucose meters (compliant with UL 60601-1:2023) for electric shock risks.
3. Checking sensor housing gaps in mini industrial temperature probes (per UL 61010-1:2023) to avoid live-part exposure.
4. Quality control for smartwatch charging pin openings during manufacturing, ensuring IEC 61032 compliance.
5. Post-production testing of small laboratory pipette controllers (narrow vent gaps) to meet global safety standards.
