Accessibility Wedge Probe Set for UL 60950-1 Compliance

This Accessibility Wedge Probe Set (S5366/S5370) is designed for IT equipment testing, adhering to UL 60950-1 Figures NAF-2/NAF-3. It includes precision-machined stainless steel wedge tips—S5366 for narrow wedges and S5370 for wider ones—to simulate accidental insertion into equipment openings such as port slots and vent edges. Equipped with insulating nylon handles for safe handling, both probes apply minimal force to ensure that hazardous live parts or moving components remain inaccessible. Durable and dimensionally precise, this set is vital for manufacturers to achieve global IT equipment safety compliance.

Specifications:
Parameter S5366 (UL 60950-1 Figure NAF-2) S5370 (UL 60950-1 Figure NAF-3)
Probe Type: Narrow Wedge Accessibility Probe, Wide Wedge Accessibility Probe
Wedge Material: Stainless steel (rigid, corrosion-resistant)
Handle Material: Nylon (insulating, non-slip, heat-resistant)
Core Function: Tests narrow gaps in IT equipment for hazardous part access, Tests wider gaps in IT equipment for hazardous part access

Test Procedures:
1. Inspect both probes for damage (bent tips, cracked handles) to ensure accuracy.
2. Power on the IT equipment and let it reach normal operating mode.
3. Select S5366 (narrow gaps) or S5370 (wider gaps) based on the test area.
4. Hold the nylon handle and align the wedge tip with the target equipment opening.
5. Gently insert the wedge toward internal hazardous parts—avoid force.
6. Check if the wedge touches live components/moving parts, then record pass/fail.

Applications:
1. Safety testing of laptop port slots (USB-C, HDMI) using S5366 (UL 60950-1).
2. Compliance checks for router vent gaps with S5370 to block access to internal wiring.
3. Verification of server chassis edges (narrow seams) using S5366 per UL 60950-1.
4. Quality control for desktop monitor bezel gaps (wider slots) with S5370 during manufacturing.
5. Post-production audits of office equipment for safety compliance.
