Product Introduction:
IEC 60335 50mm Circular Stop Face Test Finger Probe which compliant with the rigorous safety standard IEC60335 20.2, this Test Finger Probe features a 50mm diameter circular stop face—replacing the non-circular design of conventional probes—to deliver precise and reliable performance for safety testing scenarios. Functionally aligned with IEC 61032 Test Probe B, it retains core operational compatibility while introducing a key design upgrade: the 50mm circular stop face, engineered to enhance accuracy in verifying access to hazardous live components or mechanical parts of household and similar electrical appliances.
Specifications:
• Stop Face Specification Circular shape, diameter: 50mm
• Key Dimensions Insulating guard: ø12mm; Handle section: ø75mm; Overall length: 160mm
• Precision Tolerances Cylindrical radius (R2): ±0.05mm; Spherical radius (R4): ±0.05mm; All edges chamfered
• Material Composition Metal components: Durable heat-treated steel (for wear resistance); Guard/handle: High-quality insulating material
• Structural Features Articulated joints (for smooth insertion into gaps); Integrated insulating guard (to limit over-insertion)
Test Procedures:
• Inspect the probe for damage (e.g., bent metal, cracked insulation) and confirm all dimensions meet specs.
• Power off the electrical appliance under test and place it on a stable, level surface.
• Identify potential access points to hazardous parts (e.g., gaps in enclosures, exposed components).
• Hold the probe by its insulating handle, align the circular stop face with the appliance surface, and gently insert the probe into target access points.
• Check if the probe can reach hazardous parts; record results to assess compliance.
• After testing, clean the probe with a dry cloth and store it in a protected case to avoid damage.
Applications:
• Safety testing of large household appliances (e.g., refrigerators, washing machines) to prevent access to hazardous live parts.
• Compliance checks for kitchen appliances (e.g., electric ovens, microwaves) to verify protection against mechanical hazards.
• Quality control during production of small electrical appliances (e.g., vacuum cleaners, electric irons).
• Third-party laboratory testing for appliance certification (e.g., CE, UL) per IEC 60335-1 requirements.
• Post-production audits to ensure consistent safety performance across appliance batches.
