IEC 61032 Figure 5 Test Probe A — 50mm Sphere with Baffle and Handle
Leave a Message
The IEC 61032 Figure 5 Test Probe A with 50mm sphere, baffle, and handle is a specialized safety verification instrument for assessing enclosure protection in electrical equipment. It incorporates a 50mm-diameter non-conductive sphere to simulate accidental contact with large objects such as body parts or debris, a rigid baffle to prevent excessive insertion into equipment openings, and an ergonomic insulating handle for secure operation. Engineered to comply with IEC 61032 requirements, this probe ensures hazardous live or mechanical components remain inaccessible, making it essential for manufacturers and testing laboratories to validate equipment safety and achieve global compliance standards including UL, GB/T, and ISO certifications.
Specifications:
• Probe Type: IEC 61032 Figure 5 Test Probe A — 50mm Sphere with Baffle and Handle
• Test Sphere
– Diameter: 50mm ± 0.5mm
– Material: Non-conductive, impact-resistant polymer (prevents electrical interference)
– Surface: Smooth, burr-free (minimizes enclosure damage)
• Baffle:
– Diameter: 100mm ± 1mm (exceeds sphere diameter to limit insertion depth)
– Material: Rigid polymer (maintains structural integrity during testing)
– Position: 20mm from sphere surface (per IEC 61032 specifications)
• Handle:
– Material: Insulating nylon (heat-resistant, non-slip surface)
– Length: 150mm ± 5mm (ergonomic design for operator comfort)
• Core Function: Verifies that electrical equipment enclosures prevent access to hazardous parts using a 50mm spherical test object, with baffle mechanism restricting over-insertion
Test Procedures:
• Inspect the probe for integrity (absence of sphere cracks, baffle deformation, or handle wear) prior to use.
• Energize the electrical equipment and allow it to reach standard operating conditions.
• Grasp the insulating handle and position the 50mm sphere adjacent to equipment openings such as vents or gaps.
• Apply gentle pressure to advance the sphere toward the opening—terminate movement upon baffle contact with the enclosure surface (prevents excessive insertion).
