CEE 7 Gauges C 7 for Distance to Point of First Contact for 10/16A 250V Two-pole Socket-outlets

CEE 7 Gauges C 7 for Distance to Point of First Contact for 10/16A 250V Two-pole Socket-outlets is specifically designed for testing and inspecting the structure and size of 10/16A 250V two-pole socket-outlets, focusing on the distance to the point of first contact. It strictly complies with the IECEE CEE-7 standard (“Specification for plugs and socket-outlets for domestic and similar purpose”) and is widely applicable in relevant industrial fields. Its dimensions, tolerances, material properties, hardness, and surface roughness all meet standard requirements, featuring small thermal expansion coefficient of the material and stable, reliable dimensional accuracy.

Specifications:
• Complies with IECEE CEE-7 standard (“Specification for plugs and socket-outlets for domestic and similar purpose”)
• Material hardness: More than 50HRC
• Material thermal expansion coefficient: Small
• Dimensions and tolerances: Stable and reliable
• Surface roughness: Meets standard requirements
• Edges: Not rounded
• Gauge dimensions (series): 5.45 mm, 5.60 mm, 5.75 mm, 5.95 mm
• Tolerance for 5.45 mm gauge: +0.02 / -0

Test Procedures:
• Select the largest gauge from the C7A to C7D series that can enter the entry hole for plug pins of the socket-outlet.
• Fully insert the selected gauge into the 10/16A 250V two-pole socket-outlet.
• Verify that the short pin of the gauge does not reach the contact tubes of the socket-outlet.
• Confirm that the long pin of the gauge touches the contact tubes of the socket-outlet when fully inserted.

Applications:
• Testing and inspecting the structure and size of 10/16A 250V two-pole socket-outlets with respect to the distance to the point of first contact.
• Quality inspection and compliance verification in the electronics industry.
• Conformity assessment in the electrical appliance manufacturing industry.
• Inspection processes in industries related to plugs and socket-outlets for domestic and similar purposes.
