BS 546 5A Withdrawal-Pull Gauge for Contact Effectiveness

BS 546 5A Withdrawal-Pull Gauge for Contact Effectiveness is a precision testing tool designed to assess the contact effectiveness, structural compliance, and dimensional accuracy of 5A plugs and sockets according to BS 546 standards, as detailed in Figure 2 of BS 546. This gauge employs a withdrawal-pull method to verify critical contact performance, strictly adhering to the standard’s requirements for dimensions, tolerances, material properties, hardness, and surface roughness. Featuring material hardness exceeding 50HRC and a low thermal expansion coefficient, it ensures exceptional dimensional stability and reliable testing results, making it indispensable for verifying the quality of 5A electrical connection components.
