DIN VDE 0620-1 Gauge 3 Two-Pole Plug Insertability Gauge

This DIN VDE 0620-1 Gauge 3 Two-Pole Plug Insertability Gauge is a precision calibration instrument engineered to validate the mechanical insertability of two-pole plugs into fixed electrical sockets, in strict accordance with DIN VDE 0620-1 (2021-02) “Plugs and sockets for household and similar purposes – Part 1: General requirements for fixed sockets” Gauge 3 specifications. The gauge ensures socket compliance with dimensional tolerances specified in relevant industry standards, guaranteeing proper mechanical engagement and secure insertion of plugs that conform to standardized pin geometries. By simulating the maximum permissible pin dimensions of compliant plugs, this gauge serves as an essential tool for pre-test validation and quality assurance procedures in socket manufacturing, thereby enhancing electrical safety and product reliability in residential and similar environments.

Technical Specifications:

• Compliance Standard: DIN VDE 0620-1 (2021-02) “Plugs and sockets for household and similar purposes – Part 1: General requirements for fixed sockets” Gauge 3
• Compatible Standards: Sockets conforming to DIN 49075, DIN 49440-1, DIN 49440-5, DIN 49440-6, DIN 49442, DIN 49445, DIN 49447
• Pin Diameter: ø4.84 +0.02 mm
• Critical Dimensional Parameters: 23.88 +0.02 mm (reference length), 14.12 -0.02 mm (reference length)
• Pin Surface Roughness: Rz 5 μm maximum
• Angular Configuration: 20° per dimensional drawings
• Functional Verification: Both pin pairs must achieve unrestricted, complete insertion into the socket under test

Standardized Test Procedures:

1. Preparation: Insert and withdraw a standard-compliant plug with maximum pin dimensions into/from the socket 10 times prior to formal gauge testing.
2. Gauge Selection: Utilize Gauge 3 in conjunction with other specified gauges (L1, L2, L4, L5, L8) as required by the test protocol, following the prescribed test sequence.
3. Measurement Execution: Conduct testing through dimensional measurement and/or direct gauge application, ensuring adherence to manufacturing tolerances as defined in gauge technical drawings.
4. Verification: Confirm that both pin pairs on the gauge insert freely and completely into the socket without mechanical obstruction or binding.

Primary Applications:

• Quality control and pre-test validation of fixed electrical sockets for household and similar applications
• Compliance testing of socket assemblies against DIN VDE 0620-1 and related standards
• Manufacturing process verification to ensure dimensional conformity and mechanical safety
• Laboratory testing and certification procedures for electrical safety standards
