• Available in variants including Lehre 2A, 2B, and 2C
• For Lehre 2A (DIN 49440, 2P): Dimension “a” is 3.8±0.05 mm, mass is 200 g
• For Lehre 2B (DIN 49441, 2P+; DIN 49445, 3P+N+): Dimension “a” is 4.6±0.05 mm, mass is 200 g
• For Lehre 2C (DIN 49447): Mass is 300 g
• Additional dimension specifications: 6 to 10 mm range with Ø 8.5 mm; 10 to 12 mm range with relevant matching dimensions; 7.8±0.05 mm and 2.3±0.05 mm (specific dimension references)
• Withdrawal force requirement: The gauge shall not fall out of the contact socket under its own weight within 30 seconds

Test Procedures:

1. Prepare the contact socket for testing, ensuring stable and proper inspection conditions.
2. Select the appropriate gauge variant (Lehre 2A, 2B, or 2C) based on contact socket type and specification.
3. Insert the gauge into the contact socket following standard operating procedures.
4. Measure and verify the smallest opening width of the contact socket to confirm DIN VDE 0620-1:2010 compliance.
5. Conduct withdrawal force testing by observing whether the gauge falls out under its own weight within 30 seconds.
6. Record test results accurately to determine contact socket compliance with specified standards.

Applications include quality control testing of electrical plugs and sockets for household and similar purposes, ensuring dimensional accuracy and mechanical integrity per international safety standards.
