DIN VDE 0620-1 Gauge 4 Insertability Gauge for Two-Pole Plugs with Lateral Protective Contacts

This DIN VDE 0620-1 Gauge 4 insertability gauge is engineered to validate the insertability of two-pole plugs with lateral protective contacts into fixed sockets, strictly conforming to DIN VDE 0620-1 Gauge 4 standard requirements. It ensures sockets meet relevant industry compliance standards, guaranteeing smooth and secure insertion of compliant plugs while upholding user safety and product reliability.

Tailored to accommodate the structural characteristics of sockets with lateral protective contacts, the gauge serves as a critical tool for pre-test verification and quality control in electrical product manufacturing and compliance testing.

Specifications:

• Complies with DIN VDE 0620-1 (2021-02) “Plugs and sockets for household and similar purposes – Part 1: General requirements for fixed sockets” Gauge 4
• Compatible with sockets adhering to DIN 49075, DIN 49440-1, DIN 49440-5, DIN 49440-6, DIN 49442, DIN 49445, DIN 49447 standards
• Key dimensional parameters: ø37.9±0.03 mm, 32.6±0.03 mm, 2.8+0.03 mm, 19±0.05 mm
• Radius specification: R2±0.05 mm
• Recommended gauge height: 20 mm (adjustable based on the design of socket lateral protective contacts)
• Pin-related dimension: ø4.85 mm (as per product drawings)
• Enables unrestricted and complete insertion of gauge pins into the tested socket

Test Procedures:

• Prepare a plug that meets the applicable standard and has maximum pin dimensions, then insert and withdraw it into/from the socket 10 times before formal testing.
• Select the gauge (in combination with specified gauges L1, L2, L3, L5, L8 if required) and follow the designated test sequence.
• Conduct the test through measurement and/or direct use of the gauge, referring to the gauge drawings for manufacturing tolerances.
• Verify that the gauge pins can be inserted into the socket freely and fully without obstruction.

Applications:

• Quality control and pre-test validation of fixed sockets with lateral protective contacts for hous… (truncated)
