Test Finger Probe with 125mm * 80mm Circular Stop Face

Test Finger Probe with 125mm * 80mm Circular Stop Face according to IEC 60335-1 Clause 20.2 is a specialized tool for safety testing of household, commercial, and industrial electrical equipment, focusing on verifying access to hazardous live or mechanical parts. It features two interchangeable circular stop faces (125mm and 80mm in diameter) to adapt to different equipment sizes and test scenarios. Made of heat-treated steel (for metal components) and high-grade insulating material (for handles/guards), it has articulated joints for flexible insertion and an ergonomic grip—ensuring durable use and accurate compliance testing against global safety standards.

Specifications:
• Circular Stop Face Sizes Two interchangeable options: 125mm diameter, 80mm diameter
• Overall Dimensions Length (probe body): 180mm; Insulating handle diameter: 25mm; Guard diameter: 15mm
• Precision Tolerances Stop face flatness: ≤0.1mm; Cylindrical radius (R3): ±0.05mm; Spherical radius (R5): ±0.05mm
• Material Composition Metal parts: Heat-treated carbon steel (wear-resistant, corrosion-resistant); Insulating parts: Flame-retardant ABS plastic (UL94 V-0 rating)
• Structural Features Interchangeable stop faces (tool-free installation); 270° articulated joints; Non-slip insulating handle

Test Procedures:
• Inspect the probe for damage (e.g., bent metal, cracked insulation) and confirm stop faces are securely attached.
• Power off the tested equipment and place it on a stable, level surface to avoid movement during testing.
• Select the appropriate stop face (125mm for large equipment, 80mm for medium-sized devices) based on the test object.
•. Hold the insulating handle, align the stop face with the equipment’s surface, and gently insert the probe into gaps or openings near potential hazardous parts.
• Check if the probe can reach hazardous components; record results to verify safety compliance.
• After testing, remove and clean stop faces, then store the probe and accessories in a dedicated case.

Applications:
• Safety testing of large household appliances (e.g., side-by-side refrigerators, industrial-grade washing machines) to prevent access to internal live parts.
• Compliance checks for commercial kitchen equipment (e.g., large ovens, food processors) to verify protection against mechanical hazards.
• Hazard access testing for industrial electrical devices (e.g., small motors, control cabinets) during production and quality audits.
• Third-party laboratory testing for appliance certification (e.g., CE, GS) per IEC 60335-1 requirements.
•Pre-shipment safety verification for batches of electrical equipment to ensure consistent adherence to safety standards.
